Abstract
The present invention captures user's biometric data during enrollment and converts it by a given conversion parameter to create a template. It creates verification information for the conversion parameter, and enrolls it in an authentication server together with the template. The conversion parameter is stored in an IC card or the like for issuance to the user. During authentication, the authentication server verifies that the authentication terminal knows the conversion parameter, using conversion parameter verification information. Next, the authentication terminal converts user's biometric data newly captured by a conversion parameter to create matching information, and transmits it to the authentication server. The authentication server matches the matching information with the template to determine whether the user is a principal.
