| 摘 要： | 本文从传统密码学方法不能满足版权保护的现实需要出发，运用数字水印的基本理论，提出了一种基于置乱技术的数字图像水印嵌入方法，该方法利用离散傅立叶变换，对水印图像进行置乱加密和随机产生嵌入位置来保证水印的安全性，提取水印时不需要原始图像．用MATLAB实验证明该算法有较好的不可见性，能够抵挡各种几何攻击，具有较好的鲁棒性．

| Abstract: | Starting from the traditional cryptography method can not satisfy the reality needs of copyright protection, and using the basic theory of the Digital Watermark. This paper proposes a watermarking algorithm for digital image based on Scrambling. Using the DFT, this algorithm encrypts the watermark image and chooses embed position randomly to promise the safety of watermark.. The watermark can be detected without the primitive image. The experiments based the MATLAB prove the algorithm is imperceptibility and robust to some common geometrical attacks. |
