PROBLEM TO BE SOLVED: To reduce a theft risk caused on the analogy of a password. SOLUTION: A subject authentication device 101 holds the password in an authentication recording part 107 for confirming the subject, and holds a personal data such as the date of subject's birth and a phone number of the subject, in an analogizing side data recording part 109. An analogous pattern generation part 111 cuts out a character sequence from the personal data of the analogizing side data recording part 109, with a length condition corresponding to the password, to be developed in an analogous pattern recording part 113. An authentication/business selection part compares the password input from an input part 103 by a collating person, with a data sequence developed in the analogous pattern recording part 113, and service for the user by a business executing part 203 in a host device 201 is tentatively stopped when consistent in the comparison, to be communicated with the user through a mail processing part 209.
