Abstract: This paper proposes a new approach of digital watermarking, i.e. SRIW (self-recovery image immune digital watermarking). Its formulization description is given. SRIW is immune against ordinary watermarking attacks and SWIR can recovery the carrier image from itself. Its security analysis shows that the security of SRIW algorithms is equivalent to the security of its encryption algorithms when the SRIW algorithms were public. We give the implementation of SRIW in Wavelet Domain for exemplifying it and propose the special evaluation of SRIW. The simulation experiments on Matlab7.0 show that SRIW can protect the copyright of digital works more directly and effectively.

摘要: 本文提出一种数字水印实现的新思路,即免疫数字水印SRIW(self-recovery image immune digital watermarking)技术。对SRIW进行了形式化描述。SRIW具有对常见水印攻击的免疫性和对载体图像的自恢复性,安全性分析表明公开算法时SRIW安全性等价于加密算法安全性。以小波域为例给出了SRIW实现方法,提出了SRIW特有的评价标准。在Matlab7.0下进行了仿真分析,实验表明SRIW能更直接有效地保护数字产品版权。
