Steganography using reversible texture synthesis

Our approach for steganography uses reversible texture synthesis to conceal secret messages. A smaller source texture is resampled to synthesize a new texture image of arbitrary size, embedding messages during this process. This allows extraction of both the secret messages and original source texture from the synthesized stego texture. Our scheme offers variable embedding capacity proportional to the stego texture size, resistance to steganalysis, and reversible recovery of the source texture.
Steganography using reversible texture synthesis
- 1. STEGANOGRAPHY USING REVERSIBLE TEXTURE SYNTHESIS ABSTRACT We propose a novel approach for Steganography using a reversible texture synthesis. A texture synthesis process resample’s a smaller texture image, which synthesizes a new texture image with a similar local appearance and an arbitrary size. We weave the texture synthesis process into Steganography to conceal secret messages. In contrast to using an existing cover image to hide messages, our algorithm conceals the source texture image and embeds secret messages through the process of texture synthesis. This allows us to extract the secret messages and source texture from a steno synthetic texture. Our approach offers three distinct advantages. First, our scheme offers the embedding capacity that is proportional to the size of the stego texture image. Second, a steganalytic algorithm is not likely to defeat our Steganography approach. Third, the reversible capability inherited from our scheme provides functionality, which allows recovery of the source texture. Experimental results have verified that our proposed algorithm can provide various numbers of embedding capacities, produce a visually plausible texture images, and recover the source texture.
