More Information
Summary:Provided is a biometric authentication device that can enhance usability, suppress deterioration of authentication accuracy due to ambient noise, and increase tolerance to wiretapping. A biometric authentication device generates a signal pattern toward a living body by using a signal pattern generating means (11) and transmits the signal pattern to the living body in accordance with the signal pattern by a signal transmitting means (12). Further, the device receives a response signal transmitted through the living body by a signal receiving means (13). The device then calculates transmission characteristics in accordance with the signal pattern and the response signal by a transmission characteristic calculating means (14). Further, the device extracts and checks a characteristic amount in accordance with the transmission characteristics. L'invention porte sur un dispositif d'authentification biométrique qui peut améliorer l'aptitude à l'utilisation, supprimer la détérioration de précision d'authentification due au bruit ambiant et augmenter la résistance au branchement clandestin. Un dispositif d'authentification biométrique génère un motif de signal vers un corps vivant par utilisation d'un moyen de génération de motif de signal (11) et transmet le motif de signal au corps vivant conformément au motif de signal par un moyen de transmission de signal (12). En outre, le dispositif reçoit un signal de réponse transmis à travers le corps vivant par un moyen de réception de signal (13). Le dispositif calcule ensuite les caractéristiques de transmission conformément au motif de signal et au signal de réponse par un moyen de calcul de caractéristique de transmission (14). En outre, le dispositif extrait et vérifie une quantité caractéristique conformément aux caractéristiques de transmission.
