摘要： 针对Java3D应用程序固有的场景图数据结构，提出一种新的用于保护Java3D应用程序的动态数据结构软件水印算法。该算法将一个对场景图节点遍历的初始顺序作为嵌入密钥，利用循环左移及基于阶乘的进制数制方法将水印嵌入软件。阐述水印的嵌入及提取算法步骤。该算法具有不增加场景图节点个数和不影响程序性能的优势，比其他水印算法更加健壮。

Abstract: In this work, a software watermarking algorithm through hiding watermarks in scene graph data structures using in Java3D applications is presented. According to a secret initial order of scene graph traversal, a secret message is embedded through circular-left shift operation and a numbering system. The embedding and extracting technology are discussed. The method does not change the size of scene graph, and the embedded watermarks are more robust than other watermark algorithms.
