| 摘要: | When an image is created by multiple authors, it is reasonable that no single author monopolize the ownership. The ownership should be shared among these authors, and the ownership should be proved by a group of authors. In this paper, we propose a joint ownership protection scheme for co-authored images. Some of the authors or all of the authors can verify ownership. This scheme integrates discrete cosine transforms and visual cryptography to meet robustness and security requirements. The experimental results show this scheme successfully resists some common attacks. |
