AUTHENTICATION APPARATUS, AUTHENTICATION PROGRAM, AND METHOD OF AUTHENTICATION

摘要

An authentication apparatus verifies biometric information acquired from a person to be authenticated against registered information registered in advance. A biometric information acquisition unit acquires biometric information from the person to be authenticated. A determination unit determines whether or not the person to be authenticated has uncertainty of verification. An information generation unit generates first generated information from the biometric information, and generates second generated information from the biometric information, which is used for verification in addition to the first generated information when the determination unit determines that the person to be authenticated has uncertainty of verification. A verification target selection unit selects whether to set first registration information as a verification target or second registration information as a verification target in addition to the first registration information. A verification unit verifies the registration information selected as the verification target against corresponding generated information.
