The invention discloses an identity
authentication method and a device, belonging to the communication and computer technical field. The method comprises the following steps: reading the card information of an
integrated circuit (IC) card, and authenticating the IC card according to the card information; when IC card
authentication is successful, reading facial
feature data from the IC card; and authenticating the identity of a cardholder according to the facial
feature data of the cardholder and the facial
feature data read from the IC card. The invention also discloses an identity
authentication device. The security of user identity authentication can be improved by using the method and the device of the invention. In the invention, an embedded CPU is used to carry out double authentication of the IC card and the facial feature data. Compared with the prior art using a bulky PC application
system, the invention has simple structure, easy installation and use and easy popularization, can be widely applied to an
access control system, an attendance
system and other intelligent application systems, and can carry out
intelligent control on different authorities in the systems, thus meeting the demands of different users.
