PROBLEM TO BE SOLVED: To smoothly migrate authentication means without troubling a user.;SOLUTION: An authentication migration system determines whether or not agreement of a user for migration of authentication means is obtained, by referring to a migration completion flag of a database 2 when the user accesses an authentication server 1, and transmits a screen prompting the user to confirm and approve the authentication migration which includes a list of service names etc. which the user has registered to use, to display it on a user terminal 4. Then the system receives a response to confirmation and approval from the user terminal 4, updates data in the database 2 and turns on the migration completion flag. By this way, not only the authentication migration can be notified beforehand, but also the authentication means can be migrated after obtaining the confirmation and the approval of the user. The system does not trouble the user who does not use the service almost at all, because the confirmation and the approval are required when the user accesses the service which the user desires to use.;COPYRIGHT: (C)2012,JPO&INPIT
