A Survey on Steganography Algorithm Using Reversible Texture Synthesis

Shijina P A, Rekha Lakshmanan

Abstract: Steganography is used to hide the confidential information within the cover image. Stego indicates covered and graph indicate writing. In texture synthesis process a source texture image is used and hide the secret message in synthesized image. Steganography using texture synthesis process is used to cover the secret message that permits removing secret data and source texture from the stego synthetic texture. Image data hiding is a method used for rising embedding capacity effectively. In the existing method confident information is hidden in a cover image. Here, this technique is utilized to resample the small texture image and which generates a new texture image with a similar local appearance and arbitrary size. Our method gives three different advantages. First, the embedding capacity and the size of stego images are proportional. Second, steganographic method win over steganalytic method. Third, recovery of source texture. However, it still relics a challenging obstruction to produce high quality synthesis results. We suggest reversible texture synthesis for implanting the data which boost the data embedding without any distortion.
