Study of Different IRIS Recognition Methods

Iris is an internally protected organ whose texture is stable from birth to death. So it is very reliable as IRIS texture is unique in each individual, and its probability of two iris images to be same is 1/1051 proved by Dr. J. Doughman. By this we can say that it is one of most secure mechanism when security is concerned. The iris recognition technique consists of iris localization, normalization, encoding and comparison .In this paper various IRIS recognition algorithms are analyzed and it is concluded that the Doughman’s approach given highest efficiency of 99.9% and Kaushik Rai’s approach using SVM given 99.56% of overall efficiency.
