The attacks on digital watermarking increasingly become serious, with the application of digital watermarking on digital copyright protection. The attacks focus on the robustness of watermarking algorithm early, but in the recent year, the attacks focus on the protocol about the process of digital copyright protection. Through the description, definition and analysis on the protocol attacks, digital signature is applied to digital copyright protection schemes. A digital copyright protection security scheme based on PKI is presented with the analysis of security.
