Designation of iris is one of biometric recognition methods .That use modal recognition technique and is base on pictures whit high equality of eye iris .Iris modals in comparison whit other properties in biometrics system are more resistance and credit . In this paper we use from fractals technique for iris recognition. Fractals are important in these aspects that can express complicated pictures with applying several simple codes. Until, we use fractals for picture compressing and face recognition. For iris recognition use fractal dimension .But in this paper we present new method for adopting iris modals base on fractal codes .That cause to iris tissue change from depart coordination to polar coordination and adjust for light rates. While performing other pre-process, fault rates will be less than EER, and lead to decreasing recognition time, account table cost and grouping precise improvement.
