A new hybrid fuzzy-decomposed full capacity Stego-system

The aim of this paper is to introduce a new hybrid fuzzy-decomposed Stego-system for embedding secret messages into gray scale image. Experiments and evaluation metric parameters show that the Mean Square Error (MSE), Peak Signal to Noise Ratio (PSNR), Correlation (COR) and Entropy computed by the proposed system are better than those generated by the previous existing system. Thus, a high level of imperceptibility and high level of overall security had been attained.
