中文摘要：
对数字水印模型进行研究，提出了数字水印系统是一个证明系统。指出了有效、公平的数字水印系统的出错概率应满足的条件。利用码的结构性实现了数字水印系统分析，指出该方案具有很强的健壮性，可以通过使用扩展TPM技术来增强该方案的安全性。
英文摘要：
It is point out that the digital watermarking system is a proof system through researching the watermarking system model. Define the concepts of watermark embedding point and watermark detection point and give the condition of availability and fair of the watermarking system must be met. A novel watermarking scheme based on the structure of correcting code is proposed, and analysis the scheme in theory and get the result that this scheme is robust for some attack and signal processing. Finally, it is pointed out that this scheme can be translate to secure public watermark detecting system based on the extended TPM technology.
