IRIS CODE GENERATION AND RECOGNITION.

Iris is one of the important biometrics techniques. The pupil may vary in from 10% to 80% of the iris diameter, butfundamental rods & cons structure for an individual remains unique till the life time. The important thing is its feature whichhas a unique pattern and not related to genetic feature. In our work we have localized, normalized and enhanced the imageby using Daugman’s Integro-differential Operator, Cartesian to polar coordinates, Histogram equalization, reflectivelyGaussian filter was applied and then iris code were generated. Hamming distance was used for pattern matching. Theoverall success rate achieved 80%.
