Steganography Using Reversible Texture Synthesis

Abstract:

        Steganography is the method of hiding a secret information in a specified medium like image, video, Audio. It can be used to carry out hidden exchanges of information and to provide privacy for the user. This can be achieved by taking any multimedia as a carrier. The secret information should be embedded in the carrier medium in such a way that the attackers could not be able to find the existence of it. The security of the secret data and stego image quality should be maintained in both the embedding and recovering process.  The main purpose of steganography is to send secret or confidential message under the cover of a carrier signal. Two main properties of any steganographic technique are good imperceptibility and sufficient data capacity. Good imperceptibility ensures that the embedded message is difficult to detect. Steganography and cryptography are mainly used for security, but both are different.  The steganography techniques are used to hide the presence of the message and make it difficult for attackers to find the occurrence ofthe message. Most image steganographic algorithms adopt an existing image as a cover medium. The expense of embedding secret messages into this cover image is the image distortion encountered in the stego image. In this project the system proposed a novel approach for steganography using a reversible texture synthesis. The proposed algorithm can provide various numbers of embedding capacities, produce visually plausible texture images, and recover the source texture.
