The present invention relates to authentication information using bio information such as fingerprints. Identification accuracy whether a living body or a forgery (non living body) is improved to prevent an authentication error. The present invention particularly relates to an authentication apparatus (a fingerprint authentication apparatus), an authentication method, an authentication program and a recording medium. By detecting characteristics not shown in a living body that a forgery (non-living body) has, the characteristic such as uniform reducing feature by the passage of time of a gummy finger (a false finger) made like a bio finger, whether a living body or a forgery is determined, a determination error of a living body by a forgery is prevented, and authentication accuracy of a living body is enhanced.
