A Survey on Face Recognition Techniques

Events, such as major attacks, exposed weakness in most sophisticated security systems. Various supervision agencies are now more motivated to improve security data based on body or behavioral uniqueness, often called biometrics. Pin or password-based authentication procedures are too easy to crack. Face recognition is non-intrusive since it is based on images recorded by a distant camera, and can be very effective even if the user is not aware of the existence of the face recognition system. The face is the most common characteristic used by humans to recognize other people. Face recognition presents a challenging problem in the field of Pattern Recognition. It has wide range of applications such as law enforcement, banking, logical access control, national identity. In this paper, an overview of some of the wellknown methods in various categories
