"Biometrics - Iris Recognition System" A Study of Promising Approaches for Secured Authentication

To automatically identify, and authenticate an individual person biometric systems use unique features or characteristics of an individual. Since the last decade researchers are using Iris recognition for this purpose. Iris recognition technology is in more demand due to reliability and perfection towards recognition rates. Communication networks and mobile commerce are the application areas where biometrics is used to authenticate a person. To authenticate users and transactions, Iris based applications use infrared and video cameras. For identification on large scale database applications accuracy, speed and template size are important attributes. This paper outlines research made on characteristics of Iris Recognition Technology which makes it very attractive for using as an authenticating system to identify individual. The segmentation process used to locate the iris structure affects the performance of iris recognition system. The techniques which are employed for enhancing the performance of recognition during segmenting the iris and extracting the iris features are considered here.
