摘　　要：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,提出一种新的数字产品版权保护技术即数字水印。针对目前数字水印技术的研究主要集中在图像、视频和音频等方面的现象,分析了几种常用的文本数字水印技术,并按各自不同的嵌入方法对它们进行归类,设计并实现了一种基于文本内容的文本数字水印算法,利用中英文逗号的替换完成水印的嵌入与提取。测试结果表明了该算法的可行性,并分析了算法的鲁棒性、隐蔽性及水印容量。In order to protect copyright of digital products and prevent piracy, a technology-digital watermarking is proposed. With regard to the fact that digital watermarking research mainly focuses on image, video and audio, several technologies of text digital watermarking are studied, and they are categorized according to different embedding modes. A text digital watermarking algorithm is designed and implemented, and the watermark embedding and retrieval are realized by inter-converting Chinese-comma and English-comma. It proves the feasibility of the algorithm through the test of an article, and robusticity, concealment and watermark＇s capacity are analyzed.
