LSB steganography with usage of Mojette Transform for secret image scrambling

摘要

Many steganographic algorithms have been proposed until these days. They all try to hide information by relying on some of well-known techniques. However, each of these techniques has its advantages and also its drawbacks. In this paper, we have investigated a possibility of using tool known as Mojette Transform for modifying and scrambling a binary image containing secret information. The image after these processes should resemble noisy picture. Modified image is then embedded into the least significant bit plane of cover image. The used techniques should result in better values of parameters as MSE, or PSNR in comparison with performance of the classical Least Significant Bit steganography.
