The personal identification approaches using iris images are receiving increasing attention in the biometrics literature. Several methods have been presented in the literature and those based on the phase encoding of texture information are suggested to be the most promising. However, there has not been any attempt to combine these approaches to achieve(More)
The biometric identification approaches using iris images are receiving increasing attention in the literature. Several methods for the automated iris identification have been presented in the literature and those based on the phase encoding of texture information are suggested to be the most promising.

This paper introduces an efficient approach to protect the ownership by hiding iris code from iris recognition system into digital image for an authentication purpose using the reversible watermarking scheme. This scheme embeds bookkeeping data of histogram modification and iris code into the first level high frequency sub-bands of images found by Integer(More)
Iris is one of the most distinguishable features of a human body, which remains fairly stable throughout the lifetime of an individual. This makes iris recognition one of the most reliable methods for biometric based identification. This paper investigates a new technique to improve the performance of the system by using cohort information and user-quality(More)
