Abstract
A biometric authentication system has a terminal which extracts and encodes feature data for authentication from acquired biometric information, and which transmits the encoded feature data for authentication. The system has a DB for storing encrypted authentication information, a search unit which searches for encrypted authentication information included in the DB, and a decryption unit which decrypts the encrypted authentication information searched for using encoded feature data for authentication as a decryption key. Accordingly, a user is uniquely identified using the obtained authentication information. Further, a processing unit performs authentication response processing with respect to the identified user, based on authentication information obtained by decryption. Thus, authentication is implemented without limiting user and terminal combinations, without reconfiguring a service server, and without requiring a user to enter an ID or present a card at the terminal, when a user utilizes existing services from one or plural terminals.
