PROBLEM TO BE SOLVED: To provide an authentication system that enhances security strength by combining a fingerprint identification device with an authentication device having input keys into a personal authentication system. SOLUTION: As a password is input into the authentication device having input keys, the fingerprints of the fingers that press input keys are read by the fingerprint identification device, and both are matched against a fingerprint DB and a password DB. The fingerprint image read at each input keystroke is matched against the fingerprint DB for fingerprint authentication that acquires a personal identifier and a finger identifier as authentication results. The input character and the finger identifier of each input acquired by the matching against the fingerprint DB are further matched against the password DB for finger-assigned password authentication.
