Emerging Applications of Face Biometrics and Its Deception

Biometrics has nowadays been of universal interest and has been developed and used for many purposes such as for the detection of criminals and undesirables, identification and access control. Faces are of essential importance for human social life. They provide valuable information about the identity, expression, gaze, health, and age of a person. Many security systems depend upon face recognizers to identify a person. Many of these systems are passive and are deployed at places such as airline terminals. However, face recognizers are sensitive to deception attacks. Previous studies suggest that hair regions are very crucial in face recognition and the success of a recognizer depends on the success of a pre-segmentation stage which extracts the face region from the hair and the background. Deception attacks which would change the hairstyle, apply make-up or occluding objects to the face would cause many systems to fail. The face is equipped to lie the most and leak the most, and thus can be a very confusing source of information during deception. A person can get away with and best perpetrate deception through his face. This paper presents in brief about the deception that can be identified in face and emerging applications of Face recognition technologies.
