摘要
软件水印是一种新型的软件保护方式,与传统的软件保护方法不同,它不仅仅依赖于加密技术,而是通过在软件代码中嵌入某些特定的秘密信息,在必要的时候,可以通过从软件中提取出这些特定的秘密信息以证明对软件的版权。介绍软件水印的基本原理,并对典型的软件水印算法进行阐述。分析指出多功能水印技术的研究现状与发展前景。
Software watermarking is a new method used to protect the copyright of software.Unlike tradi- tional software-protecting methods dependent only on encryption techniques, software water- marking embeds certain secret information into host software codes and the embedded secret information can be extracted from the software when needed. Makes an introduction of the the- ory of software watermarking, makes discussion and analysis of typical algorithm.Finally gives the recent research circs and the prospect of the software watermarking.
