Abstract: The biometric recognition system is today’s essential need. Among the biometrics, iris has highly accurate and reliable characteristics. Iris recognition technique is used in many applications such as Aadhar card system, airport security, access control in factories, identification for Automatic Teller Machines and restricted access to police evidence rooms. The algorithms used in iris recognition are categorized into three stages: Image Preprocessing, Feature Extraction and Template Matching. We have studied the various Iris Recognition algorithms. This paper provides a review of major feature extraction methods of iris recognition. The Image preprocessing and Feature Extraction are the essential steps for accurate accuracy. Cumulative Sums Change Analysis Method of feature extraction is the more reliable than other methods. Hamming distance method is the most useful method for template matching. Various databases of iris are available that will be useful for researchers to implement the application for identification or verification
