Iris Recognition System – A Review

Abstract

Abstract — The iris recognition is a kind of biometrics technologies based on physiological characteristics of human body as compared with the feature based recognition of fingerprint, palm print, face and sound etc, the iris has some advantages such as uniqueness, stability, high recognition rate, and non-infringing etc. The iris recognition systems have made tremendous progress over the past decade, but further work remains to improve their accuracy in environments characterized by unfavorable lighting, large stand-off distances, and moving subjects. For the purpose of research and development of Iris recognition technology there are few public and freely available databases to have sample images. These iris databases contributes rich amount of iris images which were taken in different environments. In this paper we will discuss about the iris anatomy, history, general process, various implemente
