Abstract
(EN)
Disclosed are a device and a method for user authentication using a security card. The device for user authentication comprises: a card reader which, when a card is recognized, acquires a face image stored in the card; an infrared light source which emits infrared rays toward a user; an infrared camera which acquires an infrared image including the facial region of the user; a color camera which acquires a color image including the facial region of the user; and a control unit which determines a result of user authentication on the basis of at least one of the infrared image, the color image, and the face image, and generates a control signal according to the result of user authentication. The control unit performs a liveness test on the basis of the infrared image, and when it is determined that the result of the liveness test is successful, determines a result of face authentication on the basis of information about the facial region shown in at least one of the color image and the infrared image and on the basis of the face image acquired from the card.

La présente invention concerne un dispositif et à un procédé d'authentification d'utilisateur au moyen d'une carte de sécurité. Le dispositif d'authentification d'utilisateur comprend : un lecteur de carte qui, lorsqu'une carte est reconnue, acquiert une image faciale stockée dans la carte ; une source de lumière infrarouge qui émet des rayons infrarouges vers un utilisateur ; une caméra infrarouge qui acquiert une image infrarouge comprenant la région faciale de l'utilisateur ; une caméra couleur qui acquiert une image couleur comprenant la région faciale de l'utilisateur ; et une unité de commande qui détermine un résultat d'authentification d'utilisateur sur la base de l'image infrarouge et/ou de l'image couleur et/ou de l'image faciale, et génère un signal de commande en fonction du résultat de l'authentification d'utilisateur. L'unité de commande effectue un test de vivacité sur la base de l'image infrarouge, et lorsqu'il est déterminé que le résultat du test de vivacité est réussi, détermine un résultat d'authentification faciale sur la base d'informations concernant la région faciale représentée dans l'image couleur et/ou l'image infrarouge et sur la base de l'image faciale acquise à partir de la carte.
