为了有效地保护各种数字化产品的版权，防止产品被篡改、假冒和盗用，作为一种新的数字产品版权保护技术，数字水印应运而生。目前，数字水印技术的研究内容主要有图像、视频、音频和文本等，分析了当前几种常用的文本数字水印技术，设计并实现了一种基于XML的文本数字水印系统，即利用XML的标记节点和文本内容中逗号的替换完成数字水印的嵌入。通过对一篇实际文章的测试，分析并证明了该算法的可行性。

In order to effectively protect copyright of a variety of digital products, prevent tampering, counterfeiting and theft, digital watermarking emerged as a new technology of copyright protection. With regard to the fact that digital watermarking research mainly focuses on image, video and audio, this paper studies several technologies of text digital watermarking. The paper designs and implements a text digital watermarking algorithm based on the XML document. It realizes the watermark embedding by modifying the marks and replacing commas of XML document. Finally, it analyzes and proves the feasibility of this algorithm through the test of a concrete article.
