These facts, combined with faster personal computers and powerful data processing software, required a reliable copyright protection system of multimedia data (e.g. audio, images, video) against unauthorized copy, illegal distribution and forgery. Of the many approaches existent to protect digital data, especially multimedia data, digital watermarking is probably the one that has received the most interest. In this project we describe a transparency and a robust MDWT digital image watermarking algorithm. In the proposed algorithm, a multiple watermark images are embedded into segmented the RGB host image using a Discrete Multiwavelet Transform (DMWT).This algorithm greatly improves the watermarking efficiency, because its realization only requires taking DMWT or inverse DMWT (IDMWT) to the R, G, B elements of the color host image and watermarked image respectively. Our method yields fine image quality. Simulation results show that the watermarking system has good transparency
