A Study of Liveness Detection in Face Biometric Systems
نویسنده
چکیده
“Biometrics” refers to the technologies that measure and analyze human body characteristics for security purposes. The need of privacy and security in our daily life leads to this new area. Biometric systems have more accuracy when compared to traditional methods (password, key etc). It identifies and verifies the identity of a person based on one or more physiological and behavioral characteristics. That is Human body as password. The most common physical biometric traits includes fingerprint, face, ear, iris, retina, hand geometry, palmprint, DNA etc. Behavioral biometric traits include signature, gait, key strokes, speech patterns etc. Each biometric has its own strength and limitations and accordingly each biometric is used in identification (authentication) application. This paper concentrates on spoof attack against face recognition system, i.e. in this type of attack a fake biometric can be presented to sensor. This paper discusses about Introduction to The Face biometric system, Spoofing attack in Face recognition system, Liveness detection in face recognition system, Literature survey on Face Liveness detection and conclusion.

Survey on Application of Face liveness detection in attendance system
Face recognition systems are user friendly and easy to use compared to other biometric methods. These systems are susceptible to spoof attacks. It is easy to spoof face recognition systems by using photographs. It is important to incorporate face liveness detection algorithms into these systems to make it more secure. There are various techniques for face liveness detection. Deciding on a speci...
متن کاملDetecting Liveness in Multimodal Biometric Security Systems
In this paper a novel liveness checking technique is proposed for multimodal biometric authentication systems based on face and voice biometrics. Liveness detection ensures that biometric cues are acquired from a live person who is actually present at the time of capture for authenticating the identity. The proposed liveness checking technique based on corellation modelling that involves fusion...

In this paper we propose liveness checking technique for multimodal biometric authentication systems based on audiovisual mutual dependency models. Liveness checking ensures that biometric cues are acquired from a live person who is actually present at the time of capture for authenticating the identity. The liveness check based on mutual dependency models is performed by fusion of acoustic and...

Biometric authentication technologies, such as fingerprint, face, iris, and vein, have been widespread in many applications from individual portable devices to national ID management systems. Furthermore, relatively newer biometric authentication modalities including eye movement, lip-motion, etc., have been also researched and developed in order to improve an authentication accuracy and an usa...
متن کاملFace Recognition and Face Liveness
Spoofing attack is a threat for biometric authentication systems. Liveness detection aims at recognition of human physiological activities as the liveness indicator to prevent spoofing attack. Facial photograph of valid user is the most common way to spoof face recognition systems as photo attack is the cheapest and easiest spoofing approach. Antispoof problem is a challenging task before face ...
