摘要
由于文本中可容纳水印的冗余较少,文本数字水印技术极富挑战性.首先简述了文本的分类;然后介绍了文本数字水印技术领域的主要研究成果和最新进展,包括基于文档结构、自然语言处理技术和传统图像水印技术三类方法;从容量,鲁棒性,技术基础等方面比较了现有成果,分析了各类方法的主要优缺点;最后在总结现有成果的基础上展望了文本数字水印技术的前景,指出了该技术未来可能的研究重点以及待改进和研究的方向.
Because of the lack of redundancy to contain watermark in the text, it is very challenging to embed watermarks in it. In this paper text classification is summarized, and several existing research resuits and latest progress are reviewed ,which includes three main methods： based on document structure, natural language processing and conventional image watermarking. These results are compared from capacity, robustness and technological foundation aspects, and then an analysis is given concerning their main technical advantages and disadvantages. Finally the prospects of text watermarking are discussed on the basis of current study, and possible future research priorities and directions are pointed out.
