The iris recognition is a kind of the biometrics technologies based on the physiological characteristics of human body, compared with the feature recognition based on the 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 consists of iris localization, normalization, encoding and comparison. In this paper two different methods of iris recognition mechanism are analyzed. One is support vector machine and other is the Phase based method. Experimental results and data sets of both methods are also discussed. This paper also showed the table for the performance result iris methodologies.
