Abstract
A biometrics authentication device uses biometrics information to perform individual authentication. Primary and secondary verification of biometrics characteristic data from an image capture device are performed by a control unit and IC card. The biometrics character data is scrambled and transmitted between devices. The second registration data which is more important to authentication is stored within the IC card, and first registration data is registered in the IC card in a scrambled state. Security is improved, and moreover the load on the CPU of the IC chip in the IC card is reduced.
