Abstract
An authentication apparatus includes a time-information storage unit configured to store a reference time used for authentication; a biometric-information storage unit configured to store biometric information used for authentication; a biometric-information obtaining unit configured to obtain biometric information of a person; a matching-score calculating unit configured to calculate a matching score representing a degree of similarity between the biometric information stored in the biometric-information storage unit and the obtained biometric information; a current-time obtaining unit configured to obtain a current time; a threshold setting unit configured to set a threshold used for authentication, on the basis of the obtained current time and the reference time stored in the time-information storage unit; and an authentication-result determining unit configured to determine success or failure of authentication regarding the obtained biometric information, on the basis of the calculated matching score and the set threshold.
