摘要： 提出了一种利用多常量编码伪水印来对动态图水印进行保护的方法，设计了针对IPPCT结构动态图水印的保护算法。该算法通过创建多个IPPCT结构的伪水印对宿主程序功能性的依赖关系，对真实水印起到了防篡改的作用，增加了攻击者的攻击难度，从而可对该类水印进行有效的保护。

Abstract: A novel approach of dynamic graph software watermark protection with multiple constant encoding is proposed, and an algorithm to protect the watermark based on improved PPCT structure is designed and implemented. Through creating multiple dependencies of fake watermarks with the protected program, the algorithm presents many significant features, such as, tamper proofing, anti-attack, and effectiveness in watermark protection.
