Abstract
A certificate authority for certifying the validity of the collation result from a user terminal is placed on a communication network. The user terminal identifies a user himself or herself by collation by using biometrical information of the user. In response to notification of the collation result from the user terminal across the communication network, a service providing apparatus requests across the communication network the certificate authority to certify the validity of the collation result. When a certificate which certifies the validity of the collation result is notified from the certificate authority across the communication network, the service providing apparatus provides a predetermined service to the user.
