Abstract

PURPOSE:To guard the update of a password by permitting the password update means of a service processor to refer that the using password is a prescribed word and to update it to a new password. CONSTITUTION:For updating the password, data of eight digits which includes a check word as shown in a graphic is inputted from an input device 110. When the input device 110 inputs data, a comparison update part 120 compares whether leading four digits of inputted data are the same as those of the password held in a password holding part 130 at present or not. When the result of comparison is not coincident, an update request is an unjust one and inputted data is ignored. When the result of comparison is coincident, it is the just update request. The latter four digits of input data are saved in the password holding part 130 as the new password.
