Abstract: This study presents an iris identification system composed of an automatic segmentation mechanism which is based on Hough transform to locate the circular area of iris and the pupil. The area extracted from iris is then standardized in a rectangular block with constant dimensions. The instantaneous phase and the emergent frequency were used for the extraction and the coding of the single model of the iris in a biometric gauge to display it in the form of code bars. The Hamming distance was used to compare the binary code already recorded to decide on the dissension or the agreement between these code compared code .
