Abstract As vast channels for communication, such as the Internet, become more 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. In this paper we suggest a new algorithm of steganography for hiding a gray image in one another. The cover is divided into blocks of equal sizes. Each block size equals the size of the embedding image. The results drawn in this paper with the similarity equals 0.9717 are more improved and give the clear picture of the object. |
