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)

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)
