基于不完整语义理解的文本数字水印(英文)
Text Digital Watermarking Based on Incomplete Understanding of the Text
【摘要】 首先分析了现有文本数字水印存在的问题,随后给出一个基于不完整语义的文本数字水印方案.基于该方案,可以在不完整理解文本语义的情况下,将水印直接插入到文本内容中去.然后具体给出一个基于助词“的”的水印方案,并讨论了水印容量增加的问题以及水印方案的鲁棒性.实验结果表明该方案是容易实现的,且具有一定的鲁棒性.
【Abstract】 After analyzing the shortcomings of the existing text watermarking technologies,this paper presents a new incomplete semantically-based scheme.The watermark can be inserted into the content of the text without understanding the text completely.A feasible algorithm is given based on the auxiliary word “DE”.Furthermore,discussion on how to improve the capacity and the robustness of the algorithm are introduced.Experiments show that the embedding and the extraction of the watermark are easy to be realized and the algorithm itself is robust.
