PROBLEM TO BE SOLVED: To automatically update an approved token without requiring approval operation to a user again when an authentication server on which service is dependent is changed into another system.SOLUTION: In S1206, the approved token automatic renewal determination section of an application server checks whether an approved token issued by an old authentication system exists or not. In S1207, the approved token automatic renewal determination section determines whether an authenticated customer user is the same as an issuer who issued an old approved token or not. In S1208, the approved token automatic renewal determination section determines whether right of an approved token issued by a new authentication system is after the old approved token has issued or not. When determinations are affirmative at the above steps and it is determined that a service provider to which an approved token issued by the new authentication system is the same as the provider when old approved token has issued, an approval token issuance request section issues an approved token in the new authentication system in S1210 using right of a user subjected to user authentication.SELECTED DRAWING: Figure 12 |
