A novel secure channel selection rule for spatial image steganography

This paper introduces a novel secure channel selection rule for spatial image steganography. In this scheme, there are two factors considered to identify a pixel, which causes less distortion to cover image, to be modified in data hiding. The first one is an average difference between considered pixel and its neighbors. The value of the considered pixel is the second employed factor. Obtained experimental results reported on 10,000 natural images indicate the higher visual quality and security of our new channel selection rule for spatial image steganography when compared with the previous approaches.
