摘要
在Word文档中嵌入秘密水印可用来进行版权保护。提出了一种新的在Word文档字符中嵌入秘密水印的算法,该算法同时利用字体RGB颜色低位及下划线RGB颜色全部可用字节来隐藏信息,能达到每1个Word字符隐藏4个字节秘密信息的效果。经VBA编程试验,结果表明该算法隐藏率高,稳定且易于实现,具有一定的应用价值。
Copyright protection is one of the key issues in Word document.It is an effective method to embed secret watermarking into characters. A kind of watermarking algorithm is proposed. The algorithm can hide 4 bytes secret information per one character of Word documents by utilizing the low level of font RGB value and total underline color. The result of Visual Basic for applications experiment indicates that this method is reliable,has high data embedding rate and easy to be implemented. It has implementation and the application value.
