Fusion of multiple clues for photo-attack detection in face recognition systems

Description
Summary:We faced the problem of detecting 2-D face spoofing at- tacks performed by placing a printed photo of a real user in front of the camera. For this type of attack it is not possi- ble to relay just on the face movements as a clue of vitality because the attacker can easily simulate such a case, and also because real users often show a "low vitality" during the authentication session. In this paper, we perform both video and static analysis in order to employ complementary information about motion, texture and liveness and consequently to obtain a more robust classification.
