提出了一种鲁棒的多水印嵌入与检测算法,该算法基于小波域,且提取水印时不需要原始图像,保护了原始图像的安 全。在该多水印算法中,提出并使用了一种将密码学和常规的数字水印制作方法- - - 叠加法和量化调制法,有机结合起 来的新的方法,在水印嵌入时,不同的水印,生成与该水印相关的不同的密钥,在进行水印的提取时,用不同的密钥和待测的 图像提取出相应的水印。通过将密钥向第三方注册,可以获得对原始图像的所有权。(A robust multi-watermark embedding and detection algorithm, the algorithm based on wavelet domain, and extract the watermark without the original image, protect the safety of the original image. In the multi-watermarking algorithm, will be presented and used a conventional cryptography and digital watermarking production method--- superposition method and quantify the modulation method, combine the new method, the watermark embedding different watermark, associated with the watermark generating different keys, making extraction of the watermark when tested with a different image key and the corresponding extracted watermark. By the key to a third party registration, can be obtained ownership of the original image.)

说明：  场区由两个PEC板组成，它们在y和z维度上延伸到无穷大，彼此平行。PEC板之间的空间充满了空气.在问题空间的中心放了一个电流源。(The field area consists of two PEC plates, which extend to infinity in the y and z dimensions, parallel to each other. The space between the PEC boards is filled with air. A current source is placed in the center of the problem space.)
