基于二重加密的数字水印算法

An Digital Watermarking Algorithm based on double encryption

  • 摘要: 为了保护两人或者多人共有的版权利益不因单个人的泄密受到影响,本文提出了用Arnold置乱和采样置乱对水印图像进行了二重加密的方法,达到了共有图像版权保护的目的。论文还通过对二重加密与单次加密作比较,表明二重加密比单次加密的鲁棒性更好,但不可见性略差。

     

    Abstract: In order to guarantee the copyright of two or more people and protect it from single leak, this paper introduces the Arnold scrambling and the sample scrambling for watermark double encryption. The invisibility and robustness are observed and compared with single scrambling. The experimental results proved that the robustness of the double encryption is better than that of single encryption with a slightly worse invisibility. It can achieve better confidentiality requirements of copyright protection.
