Digital audio , video , and pictures are increasingly furnished with distinguishing but imperceptible marks , which may contain a hidden copyright notice or serial number or even help to prevent unauthorized copying directly 越来越多的数字音频、视频和图像开始使用独特的、不可见的标记来隐藏版权信息或序列号，以帮助发行商直接保护其产品的版权不受侵犯。

Digital watermarking is the technology which embeds copyright information including product id , text content or image logo into multimedia for copyright protection , secret communication and discrimination of the data files 所谓数字水印技术就是将数字信息如产品序列号、文本内容、图像标志等版权信息嵌入到多媒体数据中,以起到版权保护、秘密通信、数据文件的真伪鉴别等作用。
When there are several copyrights in a document , the real copyrights are hard to define . some papers present many protocols to decide which copyright is true . but these protocols are either too complex or do n ' t work well 另外,一篇文档里含有多个作者版权水印信息的时候,真正的版权信息难以确定,一些论文针对这种攻击提出了很多协议,但是这些协议过于复杂,或者在有效性上执行的不是很好。

In chapter 2 , a general digital watermarking frame is presented , including the generation , embedding and detection of watermark . in chapter 3 , the concept of watermarking channel is presented , the modes of watermarking channel and image dct coefficients is proposed , the capacity of watermarking channel is evaluated by embedding watermarks to selected still image dct coefficients in direct spread spectrum . in chapter 4 , a watermarking algorithms based wavelet multi - resolution is presented , by conjunction with human visual model , it keeps invisibility of watermark in host image and need not original image during detection 数字水印是一种新的数字媒体保护技术，它是将特定的信息(如版权信息、秘密消息等)嵌入到图象、语音、视频等各种数字媒体中，以达到版权保护等目的，同时，这种信息对宿主媒体的影响不足以引起人们的注意且有特定的恢复方法，此信息对非法接收者应该是不可见的，本文主要对数字水印的一般框架，静止图象dct系数的理论容量，图象水印的嵌入和检测，数字媒体防篡改以及数字水印的攻击等问题进行了研究，提出了两个新的水印算算法。
