摘要
根据Word文档的特点,基于颜色特征编码的思想,改进了修改字符颜色在Word文本文档中隐藏信息的算法。通过分别置换字符RGB颜色低4位的值,使信息隐藏量提高到每个字符隐藏12位信息。
According to the characteristics of Word document, by applying the thoughts of color feature coding, the information hiding algorithm based on modifying the value of character gray is improved by replacing the low bit of RGB value of character. This algorithm can get more information hiding capacity. About 12 bit data can be embedded into every character of source document.
