Abstract: In order to develop security systems for identity authentication, face recognition (FR) technology has been applied. One of the main problems of applying FR technology is that the systems are especially vulnerable to attacks with spoo?ng faces. To defend from these attacks and to enhance the reliability of FR systems, many anti-spoo?ng approaches have been recently developed. A secure system needs Liveness Detection in order to guard against such spoofing. In this paper various face liveness detection methods are discussed which are used to avoid these attacks. This helps to create a robust and accurate system to avoid spoofing attacks. The main aim of this work is to give a simple for future generation for more secured liveness detection approach.
