| 摘 要： | 提出了一种基于连词替换的文本水印嵌入方法。首先,要让水印信息通过混沌系统得到加密信息,再把加密信息与密钥进行异或运算得到待嵌入信息,然后对再对载体文本进行分词等预处理,找到所有符合替换规则的连词,根据待嵌入信息和连词替换表确定文本中的嵌入位置,修改后生成含水印文本。其特点是水印嵌入灵活,隐蔽性好,对于各种水印攻击有较强...

| Abstract: | This article presents a new embedding method of text watermarking based on conjunction replacement.The watermarking message is encrypted through a chaos system,information to be embedded is got by XOR operation on encrypted information and private key,then the carrier text is pretreated by participating words to find out all conjunctions,the embedded position of text is determined by encrypted information and conjunction replacement table and watermarking text is generated after modification.This method has... |
