The security of information and physical property is very important and difficult in today’s world. The credit card frauds and other miscellaneous activities by hacker’s and security breakings in government and other organizations has been one of the problems of modern days.
In the year 1998, sophisticated cyber crooks caused well over US $ 100 Million in loses (Reuters,
1999 [7]. our typical access control system will grant access through passwords, pin-codes etc.
while this strategy does not verify who we are,which off course does not guarantee our
security.
Biometrics technology is solution to such problems because it ensures the authentication
based on true identity of an individual.
Biometrics techniques are divided into two categories: Physiological and Psychological
.Physiological methods are more stable e.g.Face, DNA, Fingerprints. They usually sustain
for whole life except in case of injuries.
The psychological biometrics is based on functional aspects such as voice, signature and handwriting
etc. These functional aspects (behavioral) may vary due to stress, illness. However people are
easier with behavioral ID’s.
So biometrics system is essentially pattern recognition system which makes a personal
identification by determining the authenticity of specific physiologic and psychological
characteristics of an individual.
Face recognition is one of the methods of biometrics which ensures our security and
people are comfortable with it. Numerous algorithms have been proposed for face
recognition. One of those algorithms for fast recognition is eigenfaces.
Despite the intense research in this field these are the problems that still remain open for
research.
