Image Hiding

In this paper,the technology about still image copyright protection are analyzed and discussed.We will do the iterative blending calculation of the image using the discrete cosine transform to achieve the hiding of the digital image. In this paper, we show the main idea of the discrete cos transform and the digital image blending at first, then through using the methods of the iterative blending of single image to realize the propose of image hiding. At the same time ,we get the results analysis through the calculation of the pictures ’s PSNR.
