FINGERPRINT TEMPLATE MANAGEMENT METHOD AND AUTHENTICATION APPARATUS USING FINGERPRINT TEMPLATE MANAGEMENT METHOD THEREOF

摘要

The present invention relates to a fingerprint authentication device using a fingerprint template management method and a fingerprint template management method. The quality and distortion of a registration fingerprint image input from a user are calculated to determine the number of fingerprint templates of the user, Register. The registered fingerprint template authenticates the fingerprint image for authentication by comparing with the fingerprint image for authentication input from the user, and generates authentication result data for performing authentication. The authentication result data is collected for a certain period of time, and the fingerprint authentication performance may be secured by increasing or decreasing the number of fingerprint templates or updating the fingerprint template according to the collection result of the authentication result data. In addition, the amount of data required for fingerprint authentication may be reduced according to the fingerprint characteristics of the user, thereby reducing the space required for data storage.
