Zusammenfassung:	An authentication processing device (10) receives biometric data to be checked from a biometric measuring device (20); transform the biometric data that is input from the biometric measuring device (20) by using a checking transformation parameter that is different from a registration transformation parameter; and creates checking biometric data. Then, the authentication processing device (10) performs a differential transformation process on the created checking biometric data by using a differential parameter by which a transformation state transformed by the checking transformation parameter and a transformation state transformed by the registration transformation parameter have the same state. Thereafter, the authentication processing device (10) checks the transformed checking biometric data against the registration biometric data stored in a transformation registration data DB (50) and performs authentication.
