In the existing method of digital watermark, for embedding watermark information, authors modify more or less original image data through various methods to limit its robustness and security.
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。
Because the watermark is embedded redundantly in the whole band of the model, the approach is robust against various attacks.
由于水印被冗余地嵌入在模型的整个频带上，该算法可有效地抵抗多种攻击。
The original image is not needed during the watermark detecting process. The experimental results show that the algorithm has a better transparency and can resist various attacks. Especially the...
根据本算法的实验结果，该算法具有较好的透明性，对各种攻击有较强的顽健性，尤其是增强了小波域水印在面临裁剪攻击和联合攻击时的顽健性。
