1.1 INTRODUCTION

A biometrics is, “Automated methods of recognizing an individual based on their unique physical or behavioral characteristics.” For example face, fingerprint, signature, voice etc. Face recognition is a task humans perform remarkably easily and successfully.
In face recognition Features extracted from a face are processed and compared with similarly processed faces present in the database. If a face is recognized it is known or the system may show a similar face existing in database else it is unknown.

Face recognition has been a topic of active research since the 80’s, proposing solutions to several practical problems. It has been a challenging job for the researchers to develop a facial recognition system with 100% accuracy because of all the difficulties and limitations. As we know that the human face changes after a short period of time so no facial recognition system can work perfectly after a few years. It has to be updated with the latest database images of the person in order to verify the person. Also wearing spectacles, mask, mustaches may also affect the output of the face recognition system. Face recognition is a biometric which is much easier to understand, because we recognize or identify different people mostly by their faces. However the recognition process used by the human brain for identifying faces has not a concrete explanation. It has now become essential to have reliable security systems in
