Anti-Spoofing Method: A Survey on Biometric Face Recognition

In recent decades, the evolution of biometric technology from the first revolutionary works in faces and voice recognition to the current state of development such as fingerprint, face, or iris, signature or hand. This path of technological growth has naturally led to a dangerous issue that has started emerging in recent years. The conflict of this rapidly emerging technology to external attacks and, in specific, to spoofing. Spoofing, referred by the term attack in modern standards. It refers that it has ability to fool a biometric system by means of giving forged version of original biometric system into the sensor where illegitimate user acts as an genuine user. The entire biometric community, including researchers and developers has put themselves into the challenging task of proposing and developing efficient protection methods. The main objective of this paper is to provide a broad overview on anti-spoofing, with special attention to face modality
