A Compression Resistant Steganography Based on Differential Manchester Code

In the field of image steganography research, more and attention is paid to importance stego robustness. order make accessible from laboratory practical applications, it becomes critical that images can resist JPEG compression transmission channel. this paper, an algorithm with strong robustness proposed. First, robust cover elements are selected using sign DCT coefficients which kept constant before after compression. Additionally, a distortion function weighted cost adjustment method designed assign appropriate each candidate coefficient. Finally, message embedded in has minimal embedding by flipping signs coefficients, while differential Manchester code applied element positions obtain location feature. Compared prior art, our better undetectability stronger robustness, attacks social network platforms such as Facebook, Twitter, WeChat.
