Dual-key Text Watermarking Scheme Based on the Feature Vocabulary and Permuting Sentence
Cui-jian Zhao · Journal of Shijiazhuang University · 2011
On the basis of analyzing the proposed text watermarking method,this paper presents a new scheme.The document is viewed as a set of sentences in the scheme.Using the secret key of K1 and K2 and the return value of feature function,the feature vocabulary subset and sequence variable sentences subset are selected.The watermarking is embedded by permuting the sentences in the subset.To enhance the scheme capability of resisting the attack,the same watermarking is embedded in multi sentences.The paper expounds the scheme model and the algorithm of the permuting sentences.By analyzing the primary sentence level attack,it proposes the advantages of the scheme.
