| 摘 要： | 已有的数字水印方法为了嵌入水印信息，都对原图像数据采用了各种方法或多或少地进行了修改，这样做使其鲁棒性和安全性受到限制。本文利用了DCT系数提取图像的特征来构造水印，实验证明这种方法构造的零水印具有很好的性能。

| Abstract: | In the existing methods of digital watermark, for embedding watermark information, researchers modify more or less original image data through various methods, which limit their robustness and security. In this paper, zero-watermark via DCT (discrete cosine transform) is constructed. The result of experiment shows that the zero-watermark constructed by this method has good performance. |
