BIOMETRIC AUTHENTICATION USING BIOLOGIC TEMPLATES

摘要

Tools and techniques for biometric authentication obtain a biologic information input such as a fingerprint image, which is to be accepted or rejected as being input from an authentic user. Calculated matching scores show respective degrees of similarity between the biologic information input and several templates. The templates include a fixed registration biologic information template, as well as non-fixed learning biologic information templates which are subject to replacement.
