An iris recognition algorithm based on lifting integer wavelet is presented.Compared with the traditional wavelet transform which is based on convolution,the operation speed is improved and the transform from integer to integer can be realized,which is beneficial to quantify the iris information.The lifting integer wavelet transform is used to decompose the iris image and the features are extracted after the sub-image coefficients were quantified and encoded.The Hamming distance which shields noise is employed to carry on iris recognition.The experiment results show that the algorithm based on integer wavelet transform is superior on recognition rate and equal error rate,especially on the feature extraction speed.
