摘　　要：数字化技术和网络技术的发展使得人们之间的信息交流更加广泛和深入的同时,有关文本文档的数字产品的版权纠纷、非法拷贝和篡改等问题也越来越严重。文本数字水印技术作为文本文件的版权保护、完整性检测和真伪鉴定的有效方法之一,近年来有了迅速发展。重点介绍了目前现有文本水印算法:包括基于格式编码、图像、自然语言处理技术和中文汉字特征等四类文本数字水印算法,分析了其各自的优缺点,并对其今后研究发展进行总结。With development of network technology and digital technology, the exchange of information between people become more widely and deeply, at that time, copyright illegally copied and tampered of the digital products become more serious. As one of the effective methods text copyright protection, integrity detection and identification, text digital watermarking technology has gradually become a topic.Text watermarking algorithms based on the text format, image, natural language and Chinese characters are described in detail, their advantages and disadvantages is analyzed, finally the future research is discussed.
