A Review of Iris Recognition System used for feature recognition and different techniques

The biometric person authentication technique based on the pattern of the human iris is well suited to be applied to any access control system requiring a high level of security. Iris recognition is a proven, accurate means to identify people. Iris recognition system includes the preprocessing system, segmentation, features extraction and recognition. Especially we focus on image segmentation and statistical feature extraction for iris recognition process. The iris recognition system is highly depending on segmentation. A good number of identification systems based on behavioral characteristics (such as voice, handwriting, signature, speech, and keystroke) and physical characteristics (such as face, finger print iris etc) are being employed for identification of an individual. A compare has been made between these two techniques using FAR analysis, FRR analysis, memory requirement and algorithmic complexity.
