Abstract
The device outputs, to a display device, display information on a symbol which is to be moved and displayed; acquires a face image of a subject which has been captured by an image capturing device at a capturing timing while the display device displays the symbol; detects, from the face image, a line-of-sight position; determines that the subject of the face image is a living body when one or more prescribed conditions including a case in which the line-of-sight position matches a display position of the symbol at the image-capturing timing are all satisfied; and outputs an authentication result indicating success of the authentication when the subject is determined to be a living body and the biometric authentication is successful, and outputs an authentication result indicating failure of the authentication when the subject is determined not to be a living body or when the biometric authentication fails.
