In this paper, a novel reversible data hiding scheme is proposed to embed the color information of a palette image into its corresponding grayscale image by using the palette color replacement. Using the proposed scheme, two different qualities of images can be provided, they are the grayscale image and the color image, one for free access, and another for limited access, respectively. The proposed...
An iterative method for designing efficient, simple and high-capacity lossless embedding method for BMP images with a 256-color grayscale palette is presented. The proposed method is based on a palette modification scheme, which can iteratively embed message bits into pixels with the most occurrence gray value in a BMP image. In each iteration, both the overhead of removing an entry color in the palette...
