| 摘 要： | 在分析现有文本水印方法的基础上,提出一种新方案.该方案中文档看成是句子的集合.利用密钥K1,K2和特征函数返回值选择特征词汇子集和可变序的句子子集合,改变该子集合中的句子顺序来嵌入水印信息.为提高方案对水印攻击的抵御性,在多个句子中嵌入相同的水印信息.阐述了该方案的模型和句子变序算法,通过对主要句子层次上的攻击方法的分析,给出了本方案的优势. |
| 关 键 词： | 双密钥 文本水印 特征词 句子变序 特征函数 |

| Abstract: | 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 ... |
