Abstract
(EN)
Disclosed are a fingerprint authentication apparatus and method, which process fingerprint data inputted through a plurality of fingerprint sensors, in order to use the processed data in authentication, to thereby improve security and performance. The fingerprint authentication apparatus according to one embodiment of the present invention comprises: a first sensor which acquires first fingerprint data from a user; a second sensor which acquires second fingerprint data that is different from the first fingerprint data; and a control unit which determines whether or not to authenticate the user on the basis of the similarity resulting from the comparison of the first and second fingerprint data acquired by the first and second sensors with registered fingerprint data. The present invention uses a combination of fingerprint data inputted through the plurality of fingerprint sensors in authentication, to lower both the false-rejection rate and the false-acceptance rate, thereby obtaining a stable and accurate result of user authentication.

L'invention concerne un appareil et un procédé d'authentification d'empreintes digitales, qui permettent de traiter des données d'empreintes digitales entrées au moyen d'une pluralité de capteurs d'empreintes digitales, et d'utiliser les données traitées aux fins d'authentification pour améliorer la sécurité et la performance. L'appareil d'authentification d'empreintes digitales, selon un mode de réalisation de l'invention, comprend: un premier capteur qui acquiert de premières données d'empreintes digitales d'un usager; un second capteur qui acquiert de secondes données d'empreintes digitales différentes des premières données d'empreintes digitales; et une unité de contrôle qui détermine s'il y a lieu d'authentifier ou non l'usager sur la base des similitudes résultant de la comparaison des premières et secondes données d'empreintes digitales acquises par le premier et le second capteur avec des données d'empreintes digitales enregistrées. Une combinaison de données d'empreintes digitales entrées au moyen de la pluralité de capteurs d'empreintes digitales est utilisée pour cette authentification, afin de réduire tant le taux de rejet erroné que le taux d'acceptation erronée, ce qui permet d'obtenir un résultat d'authentification d'usager stable et exact.
