Abstract
An authentication processing device receives biometric data to be checked from a biometric measuring device; transforms the biometric data that is input from the biometric measuring device by using a checking transformation parameter that is different from a registration transformation parameter; and creates checking biometric data. Then, the authentication processing device 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 checks the transformed checking biometric data against the registration biometric data stored in a transformation registration data DB and performs authentication.
