Abstract :
Recently, as the fast development of the computer network communication technology, itpsilas more and more convenient for the digital information storage and transmission. Therefore, more and more attention is focused on the copyright protection of digital information. An algorithm that gray image as watermark is embedded in original color-image is introduced. This algorithm thinks over both unobtrusiveness and robustness, and the size of image is unlimited. So it has strongly practical significance.
