Human Being’s eyes are recognized as the most efficient biometric trait. Because of its great accuracy, reliability as well as originality iris recognition is included in numerous fields associated with access control as well as security. For efficient working of the iris recognition system the researchers have to face many challenges in designing an effective system. In this paper the author discusses the new way of individual identification depending upon the iris recognition developed by many researchers. It includes various techniques used by them and their effectiveness in iris recognition process.
