Abstract

Steganography is a method of information hiding. In this paper, introduce a novel approach for enhancing the security of an image by steganography using reversible texture synthesis. The texture synthesis process produces an arbitrary large and similar looking new texture from a small texture image. This algorithm conceals the source texture and embeds the secret image through the process of texture synthesis. So we can extract the secret image and the source texture from a stego synthetic texture. This method offers four distinct advantages. First, the embedding capacity is proportional to the size of the stego synthetic texture image. Second, it is very difficult for a steganalytic algorithm to defeat this steganography method. Third, recovery of the source texture from the stego image is done. Fourth, prevent loss of information due to the mirroring operation. The proposed algorithm is secure and robust against an RS steganalysis attack.
