In this paper, efficient biometric security
technique for Integer Wavelet Transform based Human
Recognition System (IWTHRS) using Iris images
verification is described. Human Recognition using Iris
images is one of the most secure and authentic among the
other biometrics. The Iris and Pupil boundaries of an Eye
are identified by Integro-Differential Operator. The features
of the normalized Iris are extracted using Integer Wavelet
Transform and Discrete Wavelet Transform. The Hamming
Distance is used for matching of two Iris feature vectors. It
is observed that the values of FAR, FRR, EER and
computation time required are improved in the case of
Integer Wavelet Transform based Human Recognition
System as compared to Discrete Wavelet Transform based
Human Recognition System (DWTHRS).
