File can comprise the rule of buying or transmitting, and described rule request and this document are bought or the transmission file associated together.For example, a first song may require it only to be sold as the part of the song collection as the special edition.Another example can require trailer, advertisement or other relevant material to be accompanied by a film or distributed TV programme.
In order to support ability according to the correct Resources allocation of a layering distribution technology, solution software on the subscriber computer can provide a kind of mechanism, whereby do not resell person and distributor their sign can be increased to one the packing media file on, this media file generally allows the person of reselling and distributor's sign, makes them to be compensated for the sale that relates in distribution channel.When a sales transactions occurring for a particular media files, the identification information that just can extract user in the distribution channel from the media file of packing is authorized to share income so that whom to determine at every turn.All Activity can be for paying and analyzing to be concentrated and follow the tracks of.The paying situation that central authorities' track database can be used for the tracking person of reselling, distributor's (may comprise the user who transmits packed file) and transmits the user of the no packed file that arrives.This back one situation can occur when for example following: the user is shared when coming from the song of a standard audio CD or DVD.The user ID of consulting can be imported when buying, and makes consultant (referrer) and the relevant person of reselling and distributor to be compensated.
The licence of file can be identified by a plurality of equipment of user.Method described here and technology can be provided for the user the management of a plurality of equipment rooms, share and the process of mobile licence.
Fig. 1 is the process flow diagram of process 100 that is used for the digital right of management document, and this document is loaded into such as on the such subscriber equipment of computing machine.Subscriber equipment comprises the software interface with I/O port, makes equipment can monitor All Files I/O, and just as fire wall, fire wall has scanned all traffics that enter and go out of computing machine, and check is moved into and shifts out all files of system.File can be loaded on the equipment with arbitrary class I/O port, comprises floppy drive, Ethernet or LAN connection, dial-up connection, CD-ROM or DVD driver, USB port, infrared data port, bluetooth or other wireless connections or is used for data transmission to subscriber equipment or therefrom transmit any other mechanism and/or the agreement of data.
When file is loaded on the subscriber equipment, file detected (step 105).The file that is detected is further checked with file identification software, so that sign this document (step 110).For example, file identification software can determine whether the file that receives represents a known song or a film (for example MP3, windows media or some other form).This document sign can be carried out by the software of realizing following technology, and described technology is described in following patented claim: the publication No. that people such as Roberts show, submit on July 31st, 2002 is 20030028796 U.S. Patent application; The publication No. that people such as Roberts show, submit on October 29th, 2002 is 20030046283 U.S. Patent application; And/or people such as the Wells publication No. showing, submit on July 22nd, 2002 is 20030086341 U.S. Patent application; All these applications all are transferred to Gracenote company, and all are incorporated into this by reference.This technology is extracted a digital finger-print from a digital document, and the fingerprint that is extracted is compared with the database of known works.More particularly, this technology can use algorithm detect media file type and media file be the possibility (shielded works for example express possibility) of interested file.Generally speaking, the built-in attribute of these algorithm checks files, rather than only according to file extension and the identification document type.Be confirmed as uninterested media file can be allowed to by, and need not further analyze this document.
If finding media file may be that institute is interested, then use additional algorithm to identify the media file (for example song of appointment, film, photo, works etc.) of appointment.Can identify and specify the finger print data of media file can be stored in central server, and visit with the Internet connection.Some files may have relevant file type, but can not be identified (if for example media file is represented the recording that the user generates, perhaps infeasible to the visit of digital finger-print central database).Can not add restriction and allow the visit of this file, but file may be marked as Unidentified (for example having visited an indication of this unidentified file by storage on subscriber equipment), this can handle in the future faster, if and media file is made a catalogue subsequently or by sign (but for example becoming the time spent in the Internet connection to the central numeral fingerprint database), identify media file when solution software may be used afterwards.If file is identified subsequently or makes a catalogue and be restricted, then can use the indication of being stored of the accessed mistake of the once unidentified file of expression to come the requirement purchasing licensee, so that continue to use this document or collect the licence fee that file is used.In some implementations, can store the data of limited quantity media file (for example 2000 first most popular song files) locally and supply fast access on computers.The finger print data of local storage can be updated periodically the variation of song files popularity (for example along with) from central server.
Even someone has attempted simulated papers (for example by changing filename, extension name or other attribute), and no matter file is to receive (for example reading compressed information with standard method) with compression or unpressed form, and above-mentioned file identification technology can both allow the accurate sign of file.This technology provides extremely low error rate less than 2% (the negative mistake less than 1% and less than 1% lookup error).
Also can use other file identification technology, such as watermark and fingerprint technique, known as the field of digital rights management.In some cases, may unnecessaryly come identification document with complicated file identification technology.But can come identification document based on filename or with the file ID attribute, described attribute can be included in the file and can be designed to is jamproof.For example, if media file is packaged, file identification software can be used for detecting packing and reads file ID information embedded in the packing.Therefore, file can identify with hidden file characteristic (for example fingerprint or watermark) or explicit file attributes (for example file identifier of storing in the file header).
In case identified file, just determined whether to permit this document on subscriber equipment, to use and/or use (step 115) by the specific user.This determines and can carry out by one or more by reference license databases that described license database can be stored in this locality (for example on subscriber equipment) and/or be stored in long-range (for example at the central server place).For guaranteeing that the license information in the license database is effective, can use one or more particular key to visit information, release license database and/or checking user, subscriber equipment and/or subscriber equipment from one's body licence, perhaps realize above-mentioned steps, following going through by communicating by letter with central server.If file is licensed, may allow user capture this document (step 120), this for example can comprise: separate the song that comprised in open file, the played file or film, storage or use the file on the subscriber equipment or by wireless or wired connection document flow is sent to subscriber equipment.Licence can be specified which kind of visit or the use of license file.
If file is not licensed, then can offer the user to a licence for buying (step 125).For example, the user may be directed to a website, buy there, perhaps a pop-up window may appear on display screen, whether wish to buy the licence of file or accept specific license terms for subscriber equipment inquiry user, and/or the user may be directed to the website of finishing purchase.Perhaps, the user has a service, and this service allows to buy in advance the letter of credit of the specific quantity that can be used for the licence purchase.As another kind of alternatives, the number of not permitting medium that uses in the specific period can be by solution software or other software at native monitoring, and this information can be used for calculating usage charges or price subsequently.License terms also can be used as a part of proposing purchasing licensee and is shown, and described clause is such as extended period, use and distribution limits and payment option.Determine then whether the user accepts licence (step 130) (having clicked the indication of accepting button or refusal button in the pop-up window by receiving the user).If the user does not accept licence, denied access this document (step 135) then.If the user accepts licence, comprise and abide by any payment terms, the user just is allowed to visit this document, and licensed license information or any other the necessary information stores (step 140) in license database of expression file.
Fig. 2 is the block diagram that is used for the representative system 200 of managing digital rights.Subscriber equipment 205 comprises a processor 210, and processor 210 can be carried out the instruction of storing in the storer 215 that links to each other with subscriber equipment 205 and/or other storage medium (not shown).Subscriber equipment can comprise some other nonvolatile memories of the essential information that BIOS (basic input/output) 220 or storage and subscriber equipment 205 are relevant.Subscriber equipment 205 can comprise one or more I/O ports 225, and described port 225 can be file and other data in the moving up and down and/or duplicating of subscriber equipment 205 (shown in 230).Processor 210 can monitor file and other data by I/O port 225 according to the instruction of storage in the storer 215, so that identify shielded (copyright is for example arranged) music, video, software or other file.
For the subscriber equipment 205 of some types,, can carry out some functions with being in the long-range assembly of subscriber equipment such as some mobile phones.For example, some mobile phones may perhaps may not expected to do like this according to using not in the storage capacity of local storage file and license information.In this case, digital document (being such as but not limited to music or video) can be spread by wireless connections and be delivered to subscriber equipment.Local data base 235 can be arranged in wireless network, determines whether subscriber equipment has the processing of the permission of access specific files also can carry out on the server in wireless network.
In many cases, local data base 235 is in subscriber equipment 205 this locality.Yet in some cases, local data base 235 (together with other storage capacity) can be positioned on network drive or other external memory storage.Mapped or link under the situation of subscriber equipment 205 at network drive or external memory storage, can use an additional information to guarantee the safety of digital document fully.Particularly, may expect to describe the data that are written to network drive or external memory storage and follow the tracks of the memory location.In addition, may expect to identify the equipment and/or the user of energy access local database 235.
When having created local data base 235 for the user and position data write BIOS, information also can be written to network drive or external memory storage.Be written to network drive or external memory storage message identification the subscriber equipment or the machine that use unique user ID and/or device id to link to each other with network drive or external memory storage.For example, under the situation of family's share service device or other shared network server, driver has a plurality of users and/or device id (or both combinations) is stored in the encrypt file on network drive or the external memory storage.When a new engine is linked driver, the identification information of new engine is added to encrypt file on network drive or the external memory storage.This identification information can be followed the tracks of (for example at central server 240 or central database 250) by the concentrated area to prevent such situation: wherein excessive user or machine are using same medium, have therefore violated the rules of permission of medium.
Fig. 3 is the process flow diagram that is used for the process 300 of install software on subscriber equipment (" solution software "), and described software control is to the visit of agent-protected file.Solution software can be carried out a plurality of different functions, comprise acquisition of information, described information is used to generate that key is communicated by letter with central server, Monitoring Files I/O system, storage and search license information, identification document (for example with Gracenote or other technology), pack the purchase of conciliating open file and being convenient to licence from local data base.Solution software can be installed on the subscriber equipment with multitude of different ways.Traditional download and software installation process are a kind of modes that solution software is installed.Installation process can begin when subscriber equipment receives packed file.Other possible installation process can comprise: use by the song of solution software packaging as beginning of current peer-to-peer network, send solution software or to link, use instant message transmission or Email and other alternatives of the server of storage solution software.Process 300 shown in Figure 3 has illustrated owing to receiving the installation that a packed file begins.
At first, create a data file (step 305).If data file is a song, then the establishment of data file may comprise the artist of recording song and create artist, label and the publisher that can supply the song of distribution together.Perhaps, independent artist can oneself produce and announce the song that is used to distribute.Song is subsequently by " move (ripped) ", comprises from the such digital source of CD or DVD or an analog source obtains song and song is encoded into mp3 file, Windows Media file, Real Player file or be used for other media formats of playback on computing machine or music/media player device.
Can be applied to media file (step 310) to a digital packaging then.Other people in content everyone (for example record label, publisher or independent artist) or the distribution chain can or strengthen digital packaging to media file application, adjusting.Digital packaging can comprise such as title, author/artist and volume/collection such attribute and appointment entitlement, the right to use, royalty right expense and transmission pays the business rules of rank (promptly can pay individual's commission along distribution chain).The information of this combination is endowed one " unique file ID " (UFID), and can be stored in the central database (see figure 2).UFID is included in the packing between arbitrary and whole transmission period, and be used as a kind of identification medium file and trigger the mechanism of appointed function, described appointed function is paid the tip of incident, file usage database update and consumer's transduction activity with (micro-payment) expense allocation such as the copyright owner.Solution software can comprise the process of integrality to prevent that UFID and packing from altering that is used for authenticating documents and UFID thereof.For example, the file identification technology of discussing about the file that do not comprise unique embedded ID above can be used for " identification " file by generating an ID who derives.Check the ID that is derived with respect to the corresponding ID that has stored then, to guarantee that file and unique embedded identifier thereof are altered as yet.
Except the information relevant with media file, packing prevents the unwarranted visit of media file.In other words, packing prevents media file, unless the user has bought licence.In fact, packing places encrypted form to file, and it requires a key can visit basic media file.When the software application electronic distribution, generally be used for protecting the conventional digital packaging of software application can be used as the packing of media file.For example, packing can be same type with the commercial packing of Digital River, and the latter can be used for distributing such software, such as the Norton Antivirus (Norton Auntivirus) of Symantec company and the franchise system of Aladdin software.In case the user for him own or for equipment purchase a licence, just use a key to untie media file.This key can receive from central server.
Generally speaking, the whole communications between subscriber equipment and the central server are all encrypted with two-stage and are occurred.At first, transmission is encrypted by SSL/TLS (security socket layer/Transport Layer Security is also referred to as secure HTTP).Secondly, the key that is sent by PKI and private key to and a symmetrical key encrypted.Can be when mounted to the certificate of subscriber equipment distribution, to guarantee to trust the communication of computing machine to central server for user equipment specific.Certificate is pointed out the sender.Central server sends to the computing machine that is sending with its PKI then.The information that the computing machine that is sending is wanted to send to it with a symmetrical key is encrypted, and encrypts this symmetric key with the PKI of central server then.Central server uses its private key symmetric key of decoding, the information of using symmetric key to decode and receive then.The example of symmetric key algorithm comprises DES (digital enciphering system), 3DES (triple des) and simple password copy algorithm.Key is PGP (Pretty Good Privacy, a Pretty good privacy) to a common examples of cryptographic algorithm.Described method can be used for information is sent to subscriber equipment from central server conversely.
Usually, each media file all has a corresponding unique key, perhaps can share a specific key between two or more media files.In order to improve security, employed special encryption method can be unique for each file.Therefore, can use a plurality of encryption technologies, packing can comprise an encryption technology identifier notifies solution software is relevant to use for separating open file for which decryption technology.But packing also can comprise an executive module, and this assembly moves when the user attempts to open packaged file.In addition, but executive module determines whether to exist effective installation of solution software on subscriber equipment.
Notice and to encrypt the license database of equipment this locality.The above-mentioned symmetric key algorithm of the general use of this encryption.In order to improve security, can add a plurality of safe floors (also as mentioned above), and when communicating by letter, change encipherment scheme at any time with central server.Described technology has used the combination of data and encryption seed (seed) value to generate symmetric key.The element of these encryption seed comprises the information for local user and/or device-specific, comprises the information of the hardware and the nonvolatile memory of the equipment of being bound to.This has improved system and has made ability to the encryption of local machine-specific.Like this, be that encryption and the tagged keys that a system generates can not use in another system.
The file of packing is generally encrypted with above-mentioned symmetric key.The content of encrypting is stored in and can carries out in the packing.Thereby; key can be used for multiple different security function, comprise between the packaged file of protection (i.e. locking) and release, the locking and unlocking local data base, protection subscriber equipment and central server and/or the central database communicate by letter, verify the user, to the central server verifying user equipment and to the user equipment authentication central server.
Subscriber equipment can receive packaged file (step 315) by the distribution of media technology of physics or electricity subsequently.For example, the user can receive packaged file on its computing machine, and described file is from such as Morpheus, KaZaA, the so reciprocity platform of Napster, Grokster; The Email that receives from another people; By from the website, the file access and the downloading process of phone or satellite network, no matter whether this website is the legal distributor of digital content; In the file of individual that sends by instant message transmission or other direct method of attachment to the individual; Or by other media, such as network linking, CD-ROM or CDR, DVD-R, Zip dish or the like.
When packaged media file is opened or visited in user's attempt (for example by double-clicking file), but the executive module of digital packaging determines whether to have existed on the subscriber equipment effective installation (step 320) of solution software.Between the installation period of solution software, central server is created a unique key, this unique key can comprise with user-dependent " unique consumer ID " (UCID) and/or a Device keys.Unique key is by generating according to pre-defined algorithm combination numerous types of data, the data that described data type comprises device-specific information, collect from user's input, the data and local data base visit and the positional information that are generated by solution software or central server.At least some parts of data or data generally are sent to central server from subscriber equipment, and central server uses the data that receive to generate unique key.Central server is encrypted this information then and information is beamed back subscriber equipment, there in the non-volatile area of information stores safety on subscriber equipment, such as BIOS.In addition, unique key makes central server can discern the consumer, makes the user can use licensed data file and receive to pay so that file " sales promotion " (transmission) is arrived other consumer.Therefore the existence of unique key and executable solution software and support file show the effective installation that has solution software on subscriber equipment on the subscriber equipment.On the other hand, if having unique key but the user has removed all or part of software and supported file, it is necessary then reinstalling solution software.
Thereby, when the user attempts to visit packaged media file, solution software reads by the internal memory of implementing the BIOS tables of data, check BIOS whether one effective unique key is arranged, described BIOS tables of data is written to SMBIOS (being called DMI) standard, as defined in " system management BIOS is with reference to standard 2.3 editions (SystemManagement BIOS Reference Specification version 2.3 (the 2.1st joint-form standard)) ", wherein unique key is written into when solution software is installed.If do not find unique key, but then the executive module of packing determines whether also not install solution software.If find unique key in BIOS, then reading unique key and reading this key with central database is effective with unique key of guaranteeing to find.Central database decipher unique key and calculating and verify a verification and.As use verification and alternative, can use other verification method, such as comprising an additional keys or the token of shaking hands in the exchange between client devices and central server.In many situations or implementation, the checking of unique key validity can be carried out by the solution software on the subscriber equipment.If unique key and verification and do not match, but then the executive module of packing determines not install at present effective solution software.If unique key and verification and coupling are then determined to exist effectively to install.In some implementations, when having limited processing resource at local system (for example in mobile phone), the process that check is effectively installed can be carried out at the central server place.
In addition, if unique key represents to have the installation of effect, the solution software that then is positioned on the subscriber equipment can be verified the solution software that is positioned on the subscriber equipment with respect to the unique identification information of solution software, and described unique identification information is included in unique key of storing among the BIOS.For example, unique key of being stored among the BIOS can comprise solution software verification and and version, may not be stored with encrypted form, and and be positioned at the solution software on the subscriber equipment verification and and version compare.If this information does not match, but then the executive module of packing determines not install at present effective solution software.Otherwise, identify effective installation.
Although it is not shown in Fig. 3, has such situation: wherein packaged file licensed (licence that is access file has been stored in this locality or the central license database), the file that does not perhaps have a packing Already on the subscriber equipment (for example, before solution software was installed on the subscriber equipment, file was moved (rip) to subscriber equipment from CD).Under one situation of back, can suppose that the user is awarded the licence of access file.In order to determine whether file has been present on the subscriber equipment, generally the memory device that needs scanning to link to each other with subscriber equipment is present on the subscriber equipment to find which file.Below further discuss permit on the subscriber equipment or the file processing on the subscriber equipment Already in.
, then on subscriber equipment, provide the proposal (step 330) of solution software is installed if but the executive module of packing is determined effective solution software is not installed at present.This proposal can for example provide in the pop-up window.Determine then whether the user accepts this proposal so that solution software (step 335) (for example having clicked the indication of accepting button or refusal button in the pop-up window by receiving the user) to be installed.If the user does not accept this proposal, just solution software is not installed, and the media file (step 340) of denied access packing.If the user accepts this proposal, then the code that comprises from the central server of storage solution software code or in pack is installed solution software (step 345).
But in case if the executive module that solution software or packing be installed in step 345 determines to have existed effective installation (and the media file of supposition packing is not as yet by user and/or licensed on subscriber equipment) of solution software in step 320, but then on subscriber equipment, provide the perhaps proposal (step 325) of packaged media file of purchase.Perhaps, the user may be directed to the purchase that can finish file and the website of permission.Determine then whether the user accepts purchase and perhaps can propose (step 350).If not, then refuse visit (step 340) to the packaged media file.
In some implementations, the installation of solution software may not occur, but up to provided the proposal of buying packaged media file perhaps in step 325 after, or even the user step 350 accept to buy perhaps can propose after.Thereby, no matter in step 320 in effective installation of whether finding solution software on the subscriber equipment and in step 345, install before the copy of solution software, on subscriber equipment, provide the proposal that purchase perhaps can (step 325) packaged media file.In this case, solution software can be mounted, and need not require to determine in step 350 whether the user accepts to buy perhaps suggestible while or afterwards, for solution software a proposal that separates and acceptance are arranged.Thereby step 345 can be made peace step 350 greatly simultaneously or execution step 350 after, and step 330 and 335 can be omitted.As another kind of alternate ways, some other execution in step 330 and 335 that can be during process 300.
If the user has accepted to buy and perhaps can propose, just obtain paying information and send it to central server (step 355) from the user.Central server can comprise a little charging system, and the sale of this system keeps track media file licence and all will be sold the each side that pays, following further discussion for each is special-purpose.If this purchase is user's initial purchase media file, then import bill information, described bill information comprises payment methods and relevant information and address and telephone contact information.Otherwise the user can select to login and use former payment methods or import new payment methods.
Payment methods are processed.If pay failure, the user just can import different payment methods and retry.If the user selects no longer retry, if or be verified without any the payment methods that provide, transaction just is cancelled, and the denied access media file.Yet, suppose and pay successfully that media file is just untied (step 360), and can suitably be stored in license information in one local data base and/or the central database.
In case solution software has been installed on subscriber equipment, solution software all medium (step 365) on just can inspection user equipment are to determine whether arbitrary media file represents shielded content.This verification can be by the scanning user device memory content and identify known media file with a file identification technology and carry out.Then the media file of being discerned is packed so that make the user can sales promotion or sell he self catalogue storehouse, following further discussion.In special implementation, media file can be based on identification and packaged, perhaps may be not packaged, attempt till I/O system by subscriber equipment sends file up to the user.In addition, may require the user is its arbitrary institute content identified purchasing licensee that does not still have licence.Yet, in some implementations, when being installed, solution software may not wish to require for residing in the file purchasing licensee on the subscriber equipment, whether have this document (if for example installing on the subscriber equipment before the solution software, the user has paid for this document and gone to undue expense) legally because can not determine the user.Yet already present file can be based on to another equipment and/or another user's transmission and packaged on the subscriber equipment.
Fig. 4 is the process flow diagram of process 400 that the content that arrives without any digital packaging on the subscriber equipment is packed, and described subscriber equipment comprises solution software.At first, create a media file (step 405), as described in conjunction with Fig. 3.Media file receives (step 410) by the distribution of media technology of physics or electricity subsequently on the subscriber equipment that comprises solution software.Therefore solution software monitors file I/O system identifies the reception of media file.By using the file identification technology, solution software is by for example extracting a digital finger-print and the fingerprint of this fingerprint and known media type is compared from media file, thereby attempts identification medium file (step 415).Determine whether media file is identified (step 420).If not, suppose that then file is not protected by copyright, perhaps can allow visit (step 425) to media file.
If file is identified, determine then that media file is whether licensed on subscriber equipment, to use and/or use (step 430) by specific user.Usually, when file was identified, the file identification technology can identify the existing UFID that is associated with media file.Use on subscriber equipment in order to determine that media file is whether licensed, solution software can determine whether UFID is stored in the local data base, and described local data base comprises the UFID that permits media file.In some cases, the user has the licence to media file, but license information may not be stored on the subscriber equipment.For example, the user may use different equipment purchases one licence.The business rules of supposing media file not restricting media file is perhaps got rid of the use of media file on current user equipment for the use (being the equipment of initial permission media file on it) of a particular device, then can permit the visit to media file.Thereby, if in local data base, do not find UFID, then can check central database to determine whether the user has the licence of media file.
If determine that media file is licensed, then may allow visit (step 425) to media file.In some cases, may determine to exist an effective licence, and may allow media file, even file is not included in user's the license database.For example, if file is loaded on the subscriber equipment from a compact disk (CD), whether solution software just may identify CD is plant-manufactured, if can be programmed that to attempt xcopy be legal or allow with hypothesis.Thereby solution software may allow from an original CD xcopy, and can be the file storage license information (seeing the step 140 of Fig. 1) that duplicates from original CD.Yet solution software also can be programmed preventing the file that receives from CD is further duplicated.Particularly, solution software can be packed the file that duplicates from CD, perhaps when identifying file, perhaps when to detect file be I/O system transmissions by subscriber equipment.
If media file is not licensed, just provide the chance (step 435) of buying the licence that uses media file to the user.If the user selects not purchasing licensee, then can refuse visit (step 440) to media file.If the user determines to buy a licence, then obtain paying information and send it to central server (step 445) from the user.Suppose and pay successfully, then can suitably be stored in the license information of media file in local data base and/or the central database (step 450).Media file also can packagedly be used for further distribution (step 455), and this has guaranteed that media file is licensed, and can make suitable expense allocation before the media file at other people.As mentioned above, media file can be packed immediately.Perhaps, media file can be left unpacked form on subscriber equipment, and it is just packaged when sending media file only to attempt I/O system by subscriber equipment the user.
Fig. 5 be used to generate the user UCID and/or to the signaling and the process flow diagram of the process 500 of the key of user equipment specific.Usually, each user has a single UCID, and each subscriber equipment has the specialized equipment key of himself.UCID can be used for identifying user with the user license information of visit central server place storage, trace file source with sign pay (promptly when the user his/her UCID has been added to the file packing and with file distributing during to other buyer) and to be used for specific customer equipment identification be to belong to a specific user.The specialized equipment key can be used for release and/or visits local license database and allow the central server marks specialized equipment.By adding one by one simply or passing through according to a certain class encryption algorithm mixing key, UCID and special-purpose subscriber equipment key also can be merged into a combination key.UCID and proprietary user equipment combination of keys are used in the proprietary user equipment that belongs to a specific user distinguishes (for example making central server can follow the tracks of licensed file resident on which equipment).
The solution software that is loaded on the subscriber equipment 505 comprises the necessary executable code of user related information (step 530) that collection is specific.Some information can be collected automatically, and out of Memory may require user's manual input.For example, can point out the user to input unique user name or " handle (handle) ", password, e-mail address and other user's input information.This information can be used for the out of Memory stored in the licence of calling party and the central database, and/or be used on the subscriber equipment 505 that a plurality of users share visit to the local data base of user's special use.Automatically the information of collecting can comprise the visit and the positional information of device-specific information (for example system's common user ID, CPU ID, MAC Address, BIOS bootstrap block) and local data base.
The solution software that is loaded on the subscriber equipment 505 also is included in the 532 necessary executable codes that connect between subscriber equipment 505 and the central server 515.Generally speaking, the connection of the Internet between subscriber equipment 505 and the central server 515 is made automatically.If it is infeasible to be dynamically connected certainly, the manual process that then begins points out the user to begin a connection (using modulator-demodular unit, network etc.).If do not make any Internet connection, then installation is withdrawed from, and wherein the information of collecting in step 530 can be stored, and uses at the Internet connection time spent trial installation UCID and specialized equipment key but be provided with the back.The installation of solution software is withdrawed from step 522,524 and 526 similarly, if solution software is to install from central server 515.Internet connection is made by the safe lane as the Secure Sockets Layer(SSL).
The information that is sent to central server 515 can be sent out on this safe lane, and information has the additional encryption (for example also using PGP except the encryption that is provided is provided SSL) to its application.The message that is sent to central server 515 can respond with a success or failure code.Can be assumed to be the transmitted message that in a definite reasonable time frame able to programme, does not receive response and fail.By using the connection of being set up, the user profile of collecting in step 530 is sent out 534 to central server 515.
If the user is not known, central server 515 just generates a UCID and/or a Device keys (step 538).UCID and Device keys can produce by making up selected quantity data item, described data item can be selected from various data available items, the visit of the user profile that receives that comprises the device-specific information that receives, collects from user's input, the local data base that receives and positional information, the data that generate by central server 515 and with the date and time or the relevant information of out of Memory of transaction.As mentioned above, UCID can with the specialized equipment cipher key combinations to create a combination key.Which data item is used and how data item is combined can be defined by the algorithm of storage in the central server 515.By generate UCID, Device keys and/or combination key at central server 515 places, then can generate at central server 515 places UCID, Device keys and/algorithm of combination key keeps safety, this can help prevent the user can generate UCID, Device keys and the combination key of personation.In addition, by using the information lacked than the whole user profile that receive from subscriber equipment 505 and/or selecting some data item to be used to generate UCID randomly, and, can further stop the reverse-engineering of UCIS, Device keys and combination key and/or the algorithm of generation UCID, Device keys and combination key by before UCID is sent to subscriber equipment 505, UCID being encrypted.
UCID, Device keys, combination key and/or additional machine specific information and other user profile become storage 540 in central database 520.UCID, Device keys and/or combination key also encrypted (step 542), UCID, Device keys and/or the combination key of encrypting is sent out 544 to subscriber equipment 505, and subscriber equipment 505 stores 546 to the UCID that encrypts, Device keys and/or combination key in BIOS 510.Key can be divided into a plurality of parts, and different keys partly can be stored in the position that separates among the BIOS.UCID, Device keys and/or combination key can be represented a PKI, and this PKI is used for the message between client computer and the central server is encrypted subsequently.Local license database is created (step 548) on subscriber equipment 505.For example, move a part of solution software code so that on subscriber equipment 505, create an encrypted license database.By the database and/or the information of storing in the database are encrypted, may prevent that the information that comprises in the database is readable, unless used suitable key.Generally speaking, license database is created on the hard disk driver of subscriber equipment 505, and a position indicator pointer is stored among the BIOS 510, but license database also can be created in BIOS 510.UCID that encrypts and Device keys and/or combination key (it comprises one or more position indicator pointers) use an industrial standard process to be written into BIOS, and described process is such as the Desktop Management Interface that is used to store extended data structure (DMI).
The consumer has a plurality of equipment and hope can use the file of having permitted on each equipment usually.Therefore in some cases, process 500 can begin on a new equipment, but is begun by the user who has UCID.Based on UCID, username and password and/or other identification information, central server 515 can determine that during search 536 user is known.The user still can install solution software on miscellaneous equipment, and logins with his/her username and password.Central server 515 can generate new UCID and generate a new equipment key (in step 538), and with new equipment information updating combination key.Like this, combination key can comprise the UCID and the device-specific information (for example specialized equipment key) of the armamentarium that the user has or uses.
When combination key was received by central database, combination key can be the known equipment of new equipment or user (using the device-specific information that comprises in the combination key) with identifying user (using the UCID part of combination key) and definite subscriber equipment by the central server deciphering.If equipment is a new equipment, new equipment just can be added to registered user's known device tabulation, and this equipment is permitted based on the licence of respective files then and used data file (for example can use the distinct device number of a media file under the situation of not buying additional license thereon).Combination key (and new equipment key) after UCID and/or the renewal also can be added to the BIOS of new equipment, and the equipment that makes can be associated with special user.When user's miscellaneous equipment was linked central server next time, the combination key after UCID and/or the renewal also can be added to the BIOS of user's miscellaneous equipment.Specialized equipment also can be associated with a plurality of users, and wherein each user has a license database that separates, and the license database that separates can be distinguished with a username and password.In addition, for the equipment that does not have solution software but be authorized to communicate by letter, can allow this equipment to use file through permitting based on the license information that is arranged in the licence storehouse with the licence storehouse in local data base or the central database 520.
In some cases, the equipment temporary visit that may allow the user to use for example to use is through the file of permission.For example, the user may wish to listen to a music file when friend's family.In this case, can be added to an optional equipment (for example having due date/time) to this equipment, file can licensed temporary permit to equipment temporarily, and perhaps file can be provided for this equipment with stream format.Yet, allow other people to visit their licence in order to prevent the user, the user may be limited to have can the licensed one limited time of the login of a while and/or this temporary permit at every turn or once only licensedly give an equipment.
Fig. 6 is signaling and the process flow diagram that has been used to visit the process 600 of this media file when the user has had the licence of media file.Process 600 comprises operation on BIOS 610, local data base 615, central server 620 and the central database 625 of subscriber equipment 605, subscriber equipment 605 and communication therebetween.Subscriber equipment 605 receives the file of a packing in the step 315 of Fig. 3.When the user attempts to open the file of this packing, can carry out packaging code and on subscriber equipment 605, move (step 630).Executable code may make subscriber equipment 605 effective installation (step 635) of check solution software earlier.Suppose and find effective installation, executable code may make effective UCID, Device keys and/or combination key (step 640) among the subscriber equipment 605 check BIOS 610, this step is included in when solution software is installed and writes under the situation of key, and the storer that the DMI form is carried out reads.
If find effective UCID, Device keys and/or combination key, the solution software on the subscriber equipment 605 just can be checked licence to packed file in the local data base 615 by sending a file license request 642.This search can be implemented (described UFID is included in the digital packaging) by the UFID of identification medium file and is attempted locating UFID and implement in local data base 615.Local data base 615 can be by comparing release to the unique machine information in one or more keys of storing among the BIOS and actual unique machine information.If information matches, solution software just can be deciphered local data base to read license information.If information does not match, then can design key, make to the trial of deciphering local data base can be not successfully unwarranted the duplicating of opposition license database to a distinct device (for example with), wherein have necessary contact central server 620 to obtain the authorization or registered user's equipment 605 (see figure 5)s.Deciphering to the license information that comprises in local data base 625 and/or the local data base 625 can be carried out with the digital cipher of storing among the BIOS, so that release local data base 625 or its content.
Suppose that local data base 625 is successfully deciphered, just response 644 that comprises necessary license information or the present indication of not permitting of expression file are turned back to subscriber equipment 605 on subscriber equipment 605.If returned license information, just allow visit (step 685) to file.Otherwise, have necessary visit central database 625 to determine that whether subscriber equipment 605 is an equipment of authorizing and/or determine whether to exist effective licence.When each visit central server 620 and/or central database, all be necessary the key stored on test subscriber's equipment the subscriber equipment 605 of relate to guarantee to communicate by letter effectively, authorizing with respect to canned data in the central database 625.Following steps have been described the test of a combination key.Although can use a combination key, other implementation also can be used UCID, Device keys and/or out of Memory.If in BIOS 610, find a combination key, then key that finds and additional machine specific information (being information or some information that original usefulness generates combination key) are sent 645 together and arrive central server 620 for checking.The combination key deciphering that 620 pairs of central servers receive is to search UCID (step 650) and embedded facility information.Central server calculates a verification and (step 655) for the unencrypted combination key in addition.Then, central server is with respect to the combination key (step 660) of canned data checking not encrypted in the central database.The checking combination key can comprise to verification and calculating.If canned data is complementary in unencrypted combination key, UCID and machine information and the central database, then the mandate 665 that continues is sent to subscriber equipment 605, the good authentication of expression combination key.If combination key be personation or from another device replication, then the machine specific information that sends together with combination key can not be complementary with canned data in the information that comprises in the unencryption key and the central server.
In response to authorizing 665, described mandate can be used once when linking central database 625 in each session, executable code makes the UFID of subscriber equipment 605 by trial positioning media file in local data base 615, thereby whether the licence (step 675) of media file is arranged in the search local data base 615.In some cases, if for example but the key information of local storage is destroyed by authorizing 665 to be updated, even so original search (642) is unsuccessful, this search also may success.If in local data base 615, do not find UFID, can search for then whether UFID is arranged in the central database 625.If in central database 625, find UFID, then upgrade 680 local data bases with license information.Suppose and located a licence, then allow to use media file (step 685).For example, solution software allows a media player application program to visit the music file of being asked.In some implementations, in case allow to use a media file on a specific subscriber equipment 605, this media file just is stored on the subscriber equipment 605 with unpacked form.Only software detection to media file when subscriber equipment 605 is replicated or moves on another equipment or the storage medium, just by solution software repeated application packing, can determine by Monitoring Files I/O system as mentioned above.In other implementation, media file can be stored on the subscriber equipment 605 with the form of packing, and can be when opening media file at every turn, unties with the license information of storing in the local data base 615 and packs.
Fig. 7 is under the user does not have the situation of licence of media file, is used for the signaling and the process flow diagram of the process 700 of media file.Process 700 comprises the operation and communicating by letter therebetween on subscriber equipment 705, local data base 715, central server 720 and the central database 725.Process 700 is to determine that the user does not have the licence of media file to begin (step 730).This determines to make in the step 675 of Fig. 6 the result to the failed searches of licence.Determine that in response to this subscriber equipment 705 notifies 735 central servers 720 to need a licence.Central server 720 responds with a payment request 740, and this request 740 is presented on the subscriber equipment 705 or the user is directed to the website that can obtain the information of paying.Subscriber equipment 705 receives paying information (step 745) from the user, and paying information is sent to central server 720.Paying information processed (step 755), comprise define how many licence fees be assigned to content everyone and/or be assigned to one or more users with disributed media file.Central database 725 usefulness represent that the information of the existing media file licence of user upgrades 760.Central database 725 also can upgrade with the paying assignment information.In addition, local data base 715 usefulness represent that the information of the existing media file licence of user upgrades 765.Based on the license information after upgrading, may allow the user to use media file (step 770) on the subscriber equipment 705.
If for example equipment can not be linked the Internet easily, then some equipment perhaps can not with the central server direct communication.The mode that media file can stop media file further not to be transferred to miscellaneous equipment with packing is transferred to this equipment.In these cases, the computer code part can be installed in the firmware, and small-sized local license database can be installed in the writable memory of equipment.Fig. 8 is signaling and the process flow diagram that is used for media file is duplicated or moves to from subscriber equipment 805 process 800 of secondary device 810.Process 800 comprises the operation and communicating by letter therebetween on subscriber equipment 805, secondary device 810, local data base 815, secondary device database 820 and the central server 825.Secondary device 810 for example can be: automobile audio system, cell phone, MP3 player or other portable set that satellite connects, and can link subscriber equipment with a cable, described cable includes but not limited to: IEEE 1394 firewire or USB cable perhaps can connect by wireless connections.A solution software version can be installed (for example when dispatching from the factory) on secondary device 810 in advance.
The request of transmission medium file is received (step 830) by subscriber equipment 805.In response to this, subscriber equipment 805 is to secondary device 810 requests one device id.Secondary device responds 840 with its device id.Subscriber equipment 805 confirms that the business rules that comprises allows the transmission (step 845) of being asked in the packing of media file.For example, business rules can be made restriction to the number of devices that media file copied to.Suppose that transmission is allowed to, then Bao Zhuan media file and corresponding license information can be transmitted 850 to secondary device 810.Secondary device 810 can be stored in license information in the secondary device database 820 (step 855).Collaborative preassembled solution software, license information can allow the media file of secondary device 810 visit packings.In addition, subscriber equipment 805 can upgrade the local license information (step 860) in the local data base 815.This renewal can be stored such information, and a copy of described information representation media file has been transferred to secondary device 810.
Subsequently, can set up 865 between subscriber equipment 805 and central server 825 connects.This connection can be set up in response to following attempt or requirement: the attempt of visit new media file, the attempt of location license information or the licence of subscriber equipment 805 periodically being verified storage in the local data base 815 are to continue the requirement of occupancy permit.By using this connection, the licence of storage upgrades and can be uploaded 870 to central server 825 (and being stored in the central database) in the local data base 815, makes central server can keep following the tracks of on it and has located the equipment of media file copy and prevented that media file is copied on the equipment more equipment that allows than business rules.Central server 825 also can be verified the existing licence of storage in 875 local data bases 815.
Also can provide technology, with the distribution of supporting media file between the user and make the user can benefit from the income that its media file produces to the result of other people distribution.The user can electronics mode send other the relevant consumer information of media file that has or appreciate with him.If make sale owing to transmitting the result, the user may earn the certain percentage of the income that follow-up sale generated of media file sale and media file.Media file comprises such information, and described information receives under the situation of media file from a person of reselling who identifies and distributor the user, the information that identifies original person of reselling and distributor and identify the user of further distribution media file.Based on the business rules that is associated with file, this information makes the person of reselling and user can receive the compensation of the purchase of making when transmitting media file.In addition, when file was sent out or receives with unpackaged form, the user of indication, the person of reselling and distributor still can be compensated, as long as their unique identification is included in the transaction data.For example, the buyer may identify the user of an indication, and central server can determine how the user of indication receives file and reconstruct distribution chain under this situation, comprises that those people of sign should share income.
Business rules can determine not have the user of media file licence whether still can benefit from the distribution again of media file.For example, the user can be stored at file on the server, as point of departure again and again, and can receive the transmission participating fee, even the user does not have the licence of the file that he is distributing.
Begin when friend sends the process of file as the people, the up-to-date packing version of solution software creation media file is prepared media file is used for transmittance process.This new packing comprise media file UFID, be applied to the business rules of media file and the UCID of originating user, the user is compensated when the song that sales promotion is bought by the user that receiving.The person of reselling and distributor's id information also can be included in the packing.When using subscriber equipment to move (rip) CD or DVD, solution software is carried out same process.For example, when the song on the CD was moved on the computing machine, the licence of song was installed in the license database.Subsequently, if the I/O system transmissions song by computing machine, then a packaging applications in song.Packing can comprise permission and paying information, and described information can be based on the song identity information that comprises in institute's move or based on the song identity information with file identification technology discussed above acquisition, and searched from central database.If song is burnt on the CD, the file of packing just can be written into CD.Perhaps, solution software can be created a pair of session id in the PC of CD readable region, and this pair session id comprises the media information file, such as the UFID and the UCID that have the person of reselling and distributor's information.In two session CD forms, the traditional audio file of audio portion branch permission at CD allows CD to play on the CD Player of routine.Yet if file is loaded in the equipment that solution software is installed on it, file can require permission.
