Document Type and Number:
WIPO Patent Application WO/2019/151368
Kind Code:
A1
Abstract:
In order to enable the reliability of biometric authentication to be improved with a method in which a processing load is lower, the present invention outputs, to a display device, display information on a symbol which is to be moved and displayed on the display device; 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, the position of the line of sight which is a position on the display device that is present at the end of the line of sight of the subject; 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 matches a display position of the symbol at the image-capturing timing are all satisfied; performs biometric authentication on the basis of the face image; and outputs an authentication result for 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 for indicating failure of the authentication when the subject is determined not to be a living body or when the biometric authentication fails.
