基于零水印和认证水印的双水印方案

A Double Watermark Scheme for Image Based on Zero-watermark and Authentication Watermark

为解决高值图像同时具有版权保护和内容认证需求的问题,提出了基于零水印和认证水印的双水印方案。实验表明,该方案具有篡改敏感度高和水印鲁棒性强的特性,性能可靠,可以同时实现对高值图像的版权保护和内容安全认证。

in order to solve the problem that some expensive images not only have the needs of protecting their copyrights but also have the needs of assuring their integrity, a new scheme is proposed. The experiments have demonstrated that this scheme has good performance; sounds robustness and can achieve the good protection of copyrights and image content authentication for the expensive color images.
