Abstract :
A novel scheme of histogram-preserving steganography is proposed in this article. In this new scheme, the problem of statistical restoration is interpreted as a Linear programming problem and solved using maximum flow algorithms. The experimental results show that our scheme can effectively diminish the relative entropy between the cover and stego images even when the information is embedded at the maximum rate.
