FACE AUTHENTICATION DEVICE, FACE AUTHENTICATION METHOD, AND PROGRAM

摘要

The present invention provides a technique for preventing an unauthorized user from using a terminal and ensuring secure use of the terminal. A presentation pattern display unit 5 that is provided at a different position from a key input unit displays an instruction for a user to input a key pattern during face authentication, and a built-in camera 1 captures a face of the user and/or a movement of a portion of the face of the user during a portion of or the entire time from when the presentation pattern display unit 5 displays the instruction to when the key input through the key input unit 10 is completed, so that it is determined whether the captured face image is of a living body.
