| 摘 要： | 介绍了动态图软件水印技术的编码方法，提出了一种结合排列图编码和PPCT的新的编码方案。该方案利用了PPCT编码纠错能力强、抗攻击性能好的特点，同时也兼顾了排列图编码方法编码率高、编码范围广的特点。其生成水印的时间也比PPCT短。

| Abstract: | This paper summarized the technique and taxonomy of software watermarking. It also described the encoding approaches of dynamic software watermarking in detail. A new scheme was proposed, which utilized permutation encoding and PPCT. The new scheme took the advantage of PPCT, which had a high resiliency, and of permutation encoding, which had high data rate. Moreover, the time to generate the watermark is shorter than that to generate PPCT. |
