Title (EN) FACE LIVENESS DETECTION USING BACKGROUND/FOREGROUND MOTION ANALYSIS
(FR) DÉTECTION DE VIVACITÉ DE VISAGE À L’AIDE D’UNE ANALYSE DE MOUVEMENT D’ARRIÈRE-PLAN/PREMIER PLAN
Abstract:
(EN) Face recognition systems are vulnerable to the presentation of spoofed faces, which may be presented to face recognition systems, for example, by an unauthorized user seeking to gain access to a protected resource. A face liveness detection method that addresses this vulnerability utilizes motion analysis to compare the relative movement among three regions of interest in a facial image, and based upon that comparison to make a face liveness determination.
(FR) L’invention concerne des systèmes de reconnaissance de visage qui sont vulnérables à la présentation de visages parodiés, qui peuvent être présentés à des systèmes de reconnaissance de visage, par exemple, par un utilisateur non autorisé cherchant à obtenir un accès à une ressource protégée. Un procédé de détection de vivacité de visage qui traite cette vulnérabilité utilise une analyse de mouvement pour comparer le déplacement relatif entre trois régions d’intérêt dans une image faciale, et, sur la base de cette comparaison, pour réaliser une détermination de vivacité de visage.
