Description: 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. Platform: |

Description: 人们借助于计算机、数字扫描仪、打印机等电子设备可以方便、迅速地将数字信息传输到所期望的地方。随之而来的副作用是这些数字形式的数据文件或作品使有恶意的个人和团体有可能在没有得到作品所有者的许可下拷贝和传播有版权的内容。由于传统的密码技术无法完全解决版权保护的问题，近年来国际上提出了一种新型的版权保护技术——数字水印技术。(With the aid of computers, digital scanners, printers and other electronic devices, digital information can be easily and quickly transmitted to the desired place. The consequent side effect is that these digital forms of data, documents, or works make malicious individuals and groups likely to copy and disseminate copyrighted content without permission from the works owner. Because the traditional cryptography can not completely solve the copyright protection problem, in recent years, a new type of copyright protection technology - digital watermarking technology has been put forward internationally.)
