Abstract: In order to solve the problem that some expensive images not only have the needs of protecting their copyrights but also have the needs of assuring their integrity, a new scheme is proposed. The experiments have demonstrated that this scheme has good performance; sounds robustness and can achieve the good protection of copyrights and image content authentication for the expensive color images.
