Abstract :
Digital watermark is a newly proposed means to protect copyright of digital products, and many schemes have been proposed. A fractal-based watermark scheme is one of them. In order to improve the robustness and image quality, some aspects of the method are modified in this paper. Tests have been performed and very promising results have been obtained
