Summary:With the rapid development of computer network, digital watermarking, which is an effective digital products copyright protection technology, was widely applied in the security forensic. Those were analyzed that are the defects of existing time stamp scheme of digital watermarking and the characteristics of the pseudo-random sequence. The new scheme based on time stamp and pseudo-random sequence was proposed. Indistinguishability and scalability of watermark were analyzed from the experimental results. And other two aspects were obviously improved in the new scheme, which were in improving protocol’s security and reducing the quantity of data embedded in digital works.
