Fingerprint authentification apparatus and method using a plurality of sensor

The fingerprint authentication apparatus and method that improves the security and performance is started by the processing of fingerprint data inputted through the plurality of fingerprint sensors used in the authentication judgment. The fingerprint authentication device according to an embodiment of the present invention the second sensor, and the obtained first fingerprint to obtain as a first sensor and the second is different from the first fingerprint data and a first fingerprint of acquiring fingerprint data from a user and the data having the degree of similarity by comparing the two registered fingerprint data with fingerprint data, respectively, and a controller that determines whether the user authentication. Thus, by the authentication by using a combination of fingerprint data inputted through the plurality of fingerprint sensors, lowering both the false rejection rate and other acceptance rate stable, it is possible to obtain accurate user authentication result.
