摘要
本文提出了一种基于动态二叉树的水印基数编码方案,并对水印中的常量进行编码以达到水印防篡改的目的。同时,不仅形式化地定义了水印系统的常用算法,而且给出了该方案较为详细的实现步骤,最后进行了简单的性能分析。
In this paper a novel radix encoding scheme based on dynamic binary-tree is presented, and the constants existed in the watermark is encoded to tamper-proof the watermark itself. We not only define formally the common algorithms in the watermark system,but also introduce the steps of the scheme in detail,and finally analyze the performance briefly.
