A new Algorithm for Grayscale Image Steganography

As vast channels for communication such as the Internet are becoming popular, the security of digital media becomes a greater concern. Steganography is one of the techniques used to make detecting the transmitted data over channels more difficult, as hiding a message will reduce the probability of detecting this message. It is the science of embedding information into the cover media without causing statistically significant perturbations to the cover media. The goal of this paper is to provide an overview of Steganography methods and to propose a new algorithm for hiding gray scale images.
