軟體浮水印被應用在軟體的擁有權上,是軟體保護上的重要工具,本篇討論軟體浮水印的發展,主要研究在動態圖形軟體浮水印CT演算法上,在CT演算法應用在Java技術上時,因為Java語言上的特性所遇到的問題,結合軟體工程中物件導向的分析與設計的方法,使CT演算法在Java的應用上加以改良,我們使用物件導向技術去分析物件間的關係,選擇有強關係間的物件把浮水印嵌入,使用行動結合改善物件間的弱關係,由實驗結果證明,新的方法能解決CT演算法應用在Java技術上時,因為Java語言上的特性所遇到的問題,而且新的方法能改善軟體浮水印為程式所帶來的效能及記憶體使用的問題。
Software watermarking is an important technique that enables the protection of programs and intellectual property rights. In this thesis, we discuss the development of software watermarks and the problems involved in dynamic graph-based software watermarking when applying CT algorithm is applied to Java technology. Because Java differs from traditional programming languages, we use the object-oriented analysis and design approach to solve these problems. By embedding watermarks into the input sequences on objects with strong relation, we can prevent watermark tempering. Our experimental results demonstrate that our approach not only effectively increases the difficulty and time required to tamper watermarks but also reduces memory usage and the resources required for loading these watermarks.
