This paper presented an iris recognition system in order to verify both the uniqueness of the human iris and also its performance as a biometric identification. A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual.. The iris recognition system consists of an automatic segmentation system that is based on the Hough transform, and is able to localize the circular iris and pupil region, occluding eyelids and eyelashes, and reflections,. Stegnography technique is used to hide the crypted code with the unknown encryption key like pattern, logo or an image, so only intended receiver can decrypt the iris code. Superresolution techniques have been employed to enhance the resolution of iris images and improve the recognition performance.
