The reversible information hiding based on image encryption (eirdh), the image provider is responsible for image secure data hiding and encryption for data receiver embedded into image encryption in a reversible charge in a lossless manner and restore the original image to extract the secret information. Image based hidden encryption through differential expansion of reversible data (eirdh-de) is proposed in this paper. The algorithm solves the overflow problem of one bit embedding capacity of each gray pixel (the embedding capacity is the same as the coverage image size). Finally, experimental results show that the proposed algorithm has more efficient and high-quality images than the traditional eirdh based ones.
