摘要：At present, the proposed authentication schemes can be classified into three categories. The first category is the watermarking authentication schemes in which the watermark is independent of the multimedia content. The second category is the signature-based authentication schemes in which the signature is generated by the multimedia content and is not embedded into the multimedia content. The third category is the content-based watermarking authentication schemes in which the watermark is generated by the multimedia content. However, there exists the security question in the above-mentioned three categories of the authentication schemes. In this paper, a novel concept that is called "authentication set" is used to analyze the security of the authentication schemes in detail. Several novel concepts on the authentication set are defined, which are called "Cover Authentication Set
