Abstract
An effective color image steganography method based on the module substitutions is proposed. In accordance with the base-value of the blocks, a variety of secret bits is embedded to a RGB trichromatic system by three types of module substitutions. More specifically, to alleviate further color distortion and obtain a larger hidden capacity, the R-, G-, and B-component is encoded by Mod u, Mod u-v, and Mod u-v-w substitution, respectively. Experiments show that both PSNR and hiding rate generated by the proposed method are better than those generated by the reported schemes. In addition, the resulting perceptual quality is good.
