Abstract: An in-vehicle complex biometric authentication system includes: a sensor to sense a driver's boarding of a vehicle; a controller to perform driver authentication based on biometric information sensed by multiple biometric sensors when driver's boarding in a vehicle is detected by the sensor, and to collect driver's identification information and driving habit information during operation of a vehicle when the driver authentication is succeeded; and a memory to store the identification information and driving habit information as implicit authentication information, wherein the controller further detects situation recognition information related to the implicit authentication information, after the driver authentication is succeeded, and determines whether to perform additional authentications based on the matching result of the detected situation recognition information with the implicit authentication information. According the present invention, the system can provide a biometric authentication system to which the IOT is applied.

Abstract: Provided are an electronic device performing complex biometric authentication and a control method thereof. The electronic device includes: a sensor unit including at least one sensor configured to detect biometric information, a security module to extract a genuine score from the detected biometric information and generate a biometric authentication model for determining an authentication threshold score based on the extracted genuine score at the time of user registration, and perform user authentication based on feature points acquired from the detected biometric information and the biometric authentication model at the time of the user authentication, and a controller to control an operation of the electronic device based on a result of the user authentication, wherein the security module determines whether or not the biometric information used for the user authentication is biometric information acquired from a genuine user when the user authentication fails, and updates the biometric authentication model based on the genuine score extracted from the acquired biometric information when the biometric information used for the user authentication is biometric information acquired from the genuine user. The present invention may provide an electronic device performing complex biometric authentication by using IOT (Internet of Things).
