Biometrics is an automated system that measure physical and behavioral uniqueness to identify an individual. Instead of requiring personal identification cards, keys or passwords, biometrics can identify fingerprints, face, iris, signature, or retinas of an individual for easy and convenient verification. Iris recognition is an automated method of biometric identification that uses mathematical pattern recognition techniques. It is one of the most reliable technique used for personal identification. In this paper, the authors give a brief overview of different approaches used in iris recognition system.
