利用虚词结构变换实现的动态分层文本水印
Dynamic layered text watermarking based on modification of empty word
摘要
Abstract
A new layered embedding method about text watermarking based on the empty word is presented.To improve the robustness of the algorithm,this paper makes fully use of the advantage of the syntax rules of the empty word to design a kind of layered text method,which has been realized by using the secret key to arrange the roles forming several layers.The layered text method can handle the text as a solid structure,and the embedding data have preferable robustness.关键词
