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

摘要

The present invention relates to a fingerprint authentication apparatus and a fingerprint template management method using the fingerprint template management method and the fingerprint template management method. The fingerprint authentication apparatus determines the number of fingerprint templates of the user by calculating the quality degree and the degree of distortion of the fingerprint image for registration input from the user, Register. The registered fingerprint template is compared with the authentication fingerprint image input from the user to authenticate the authentication fingerprint image and generate authentication result data for authentication authentication. The authentication result data is collected for a certain period of time, and the fingerprint authentication performance can be guaranteed by increasing or decreasing the number of the fingerprint templates or updating the fingerprint templates according to the collection result of the authentication result data. In addition, the amount of data necessary for fingerprint authentication can be reduced according to the fingerprint characteristic of the user, thereby reducing the space required for data storage.
