Steganography using indexed texture synthesis with indexed color synthesis

A novel approach for digital steganography using a indexed texture synthesis with indexed color synthesis is proposed in this paper. A texture is a small image, and is arranged arbitrarily or synthesized to obtain a large image with same appearance. A small piece of texture weaved one another with secret message. Compared to other steganographic algorithm which make use of cover image to embed the secret data, our proposed algorithm make use of indexed texture sysnthesis and indexed color synthesis to embed secret data. This method has advantages over other steganography methods. The size of the embedded data is proportional to the size of the image, it is very highly difficult to reveal the secret data by hackers since we are using double indexed approach, it is easy to get back the original texture image. Experimental results have showed that our proposed approach can provide various number of embedding capacities which produce visually plausible texture images.
