Abstract
A biometric authentication device, which uses biometrics characteristic information to perform individual authentication, prevents declines in verification speed even when numerous biometrics information sets have been registered. A control unit registers broad characteristic quantities for blood vessel image data from an image capture device, together with characteristic data for verification. And at the time of authentication the control unit uses degrees of similarity of characteristic quantities to determine an order of verification, and performs verification of blood vessel image characteristic data in the verification order thus determined. The order of verification is determined based on captured blood vessel images, so that even when numerous characteristic data sets have been registered, verification can be performed in an order of verification based on a blood vessel image of the user, and the speed of verification can be improved.
