摘要：

在版权保护应用中，针对敌手编辑一个水印放在作品中并声称他拥有版权或者他将合法水印嵌入到自己的作品中（拷贝攻击）这两个有关安全性攻击的问题，提出一种能够对视频片段和嵌入的水印进行双重验证的安全视频水印方案。提出的方案首先生成视频哈希值，然后由生成的哈希值、版权信息以及私钥构建水印。当产生版权争议时，可以通过含水印的视频哈希值、版权信息和私钥对视频片段和嵌入的水印分别进行验证，从而实现作品的所有权验证。理论分析和实验结果表明，提出的视频水印算法针对版权保护应用具有很好的安全性和健壮性。

Abstract:

In the application of copyright protection，two problems need to be attention. One is that an adversary edits a watermark to embed the work and claims that he is owner of the work. The other is that he finds a legal watermark and embeds it to his work，namely copy attack. In order to solve the two problems，a secure video watermarking scheme，which could verify the video clips and the embedded watermark，was proposed. First of all，the video hash was computed. After that，the embedding watermark was built by the video hash，copyright information and the private key. When disputes of the copyright arose，we could verify the video clips and the embedded watermark respectively with the hash value，copyright information and the private key，thereby realizing the verification of ownership of the work. Some analyses and experimental results show that he proposed video watermarking has good security and robustness for copyright protection.
