In this paper, iris recognition system using wavelet packet is presented. Computational complexity of Daubechies wavelet is less as compared to Gabor wavelets. As Gabor wavelet based iris recognition system is patented this limits the further development. In this paper, the authors propose a novel multi-resolution approach based on Wavelet Packet Transform (WPT) for iris texture analysis and recognition. The development of this approach is motivated by the observation that dominant frequencies of iris texture are located in the low and middle frequency channels. The features of the new iris pattern are compared against the stored pattern after computing the signature of new iris pattern and identification is performed.
