Abstract:
A biometric authentication device includes a fake body judgment unit that judges whether a subject is a fake body by verifying whether a biometric information value that is input from the subject is within a biometric information value range that has been registered in advance; and a biometric information value range updating unit that, when the fake body judgment unit has judged that the subject is a living body, updates the biometric information value range such that a difference between the biometric information value that is input from the subject and an end of the biometric information value range becomes larger.
