A new kind of steganography schemes for image

an article by Zhihai Zhuo (Beijing Information Science and Technology University, China) and Ning Zhong (China Youth University of Political Studies, Beijing, China) published in International Journal of Electronic Security and Digital Forensics Voume 9 Number 1 (2017)


Message security is more and more important in our modern life. As encryption arousing suspicion easily, steganography which aims at hiding secret message in a cover and has little influence on the cover becomes popular. There are many steganography algorithms having been proposed.

Most of them are based on binary, but binary sequence is longer than ternary sequence of a same decimal sequence. In this paper, to have a shorter sequence to represent secret message and protect it, we propose a new method to deal with secret message and get a binary sequence, a ternary sequence and a quaternary sequence.

For the ternary sequence and quaternary sequence, we propose a ternary JSteg method and a quaternary JSteg method; this method can keep the histogram characters. So for same secret message, our method will have less influence on the cover.
