A SURVEY ON THE IDENTIFICATION SYSTEM OF IRIS

Abstract

Iris recognition is an imperative biometrics technique used for security purposes. It works on the principle of extracting the important features of iris and have been proved to be efficient at individual recognition level with high accuracy and nearly perfect matching. These are easy to guess and crack because users prefer passwords that are easy to remember. Cards can be lost and they can be used by anyone else to gain access to a restricted area or restricted computer. Biometrics on the other hand provide a certain and easy way of authenticating persons, biometrics can be combined with some other method like password in order to form very strong authentication method It is popular because of the unique nature of human iris. The process of iris recognition is real-time, highly accurate and reliable. Iris recognition has many practical uses, like it can be used to authenticate a person’s identity or to identify a certain person from a large set of databasesThe iris recognition system consists of image acquisition, segmentation, normalization, encoding and comparison. The Iris feature of two eyes of same person are not similar making it more secured way of authentication compared to other Biometric recognition systems. This paper provides a review of various methods and algorithms used for Iris recognition system.
