A New Scheme for Information Hiding Based on Digital Images

Digital steganography is a kind of data security technique. In this paper, a new information hiding scheme was proposed. In this scheme, we embed secret message into still digital images based on (7,4) Hamming Code and Wet Paper Codes. It embeds seven secret bits into a pixel-group of seven cover pixels at a time at first, if that is unsuccessful, it embeds the first three secret bits into that pixel-group once again. The simulation experiments show that the proposed scheme can achieve high embedding efficiency and large embedding payload.
