摘要
应用程序设计技术实现软件水印,比较了两种当前主流的软件水印实现方式,研究了一种与软件开发过程同步的软件水印技术,从软件水印的嵌入和提取两个方面对这种新的软件水印技术进行描述和形式化证明,开发出一个同步嵌入软件水印的示例程序来演示软件开发商信息的嵌入和提取过程。结果表明采用程序设计实现的软件水印技术可以很好地完成软件版权信息的隐藏和提取工作,是一种用于版权保护工作的有效方法。
This paper studied software watermark implemented by programming. After comparing the two main ways to implement software watermark,a new kind of software watermark developed together with software itself was researched in this paper. The processes of embedding and extracting and the formal proof of the new software watermark were described. A demonstration of synchronous embedding software watermark showed how to embed and extract the declaration of the ownership. The result indicate that software watermark based on programming could well complete the mission of hiding and extracting the software copyright information and could be an effective method of copyright protection.
