A New Watermarking Scheme for Quantum RGB Digital Images

In the present paper, a new watermarking scheme for quantum RGB digital images is proposed. Using the proposed scheme, the color channel of interest of each pixel is chosen according to the corresponding qubit pair of the generated randomized binary image. The security of our proposed scheme is insured through the randomization of the key image. Results of Simulations of real images show that not only the final watermarked images can't be recognized visually from the original ones, but also the histogram diagrams of these images are approximately similar. In addition, the average PSNR ratio calculated from the simulations is significantly higher than the PSNR ratios of previous proposed quantum image's watermarking methods.
