摘要
根据Word文档的特点,利用字符下划线颜色的冗余信息,设计了通过改变字符下划线RGB颜色值在Word文本文档中隐藏信息的算法,该算法不仅可以使用盲检的方法实现,而且隐蔽性更强,信息隐藏量可提高到每个字符隐藏24位信息。
According to the characteristics of Word document, the information hiding algorithm on modifying the RGB value of the character underline in the Word text document is designed by using redundant information of the character underline gray. This algorithm can not only be realized by blind detection, but also get more efficient imperceptibility and information hiding capacity. About 20 bit data can be embedded into every character of source document.
