Pixel Swap Method to Shroud Information

Reena M. Patel; D. J. Shah

Steganography is an art of secret communications. Its main purpose is to hide the occurrence of communication over a public channel. Steganalysis is the art and science of detecting a secret communication. Data hiding methods, there have been a number of steganography embedding techniques proposed over the past few years. In turn the developments of these techniques have led to an increased interest in steganalysis techniques. Steganalysis techniques have become more attractive since they work independently of the embedding technique. In my paper I go to discuss about pixel sweep method based on DCT in transform domain which use in stegnography. In this paper, authors’ goal is to compare result with of available algorithm with modified algorithm and discuss about their capacity, delectability (perceptibility), robustness to attacks, PSNR and their Histogram.
