A Resilient Watermarking Scheme for Compressed Images Using Iris Recognition

Watermarking is a technique to hide data and embedded inside an image to show authenticity or proof of ownership. Digital image watermarking technique has been presented and widely researched to some important issues in the Digital world such as copyright protection and content authentication. The proposed work presents a new digital color image watermarking method using Iris recognition.

In this method the color image is compressed using Discrete Cosine Transform (DCT) and protect the ownership by hiding the iris code from iris recognition system into a digital color images. The watermark is embedded into the luminance component of the color image. By applying the inverse DCT process the original image and iris code are extracted from the watermarked image. This method results robustness against various image processing operation.
