基于Word文档缩放字符比例的信息隐藏算法研究

On Information Hiding Algorithm Based on Changing Character Scaling in Word Document

根据Word文档的特点,提出了通过改变Word文档字符缩放比例,在文档中嵌入秘密文本的信息隐藏算法,实验表明:算法简单,很好地实现了秘密文本的嵌入,信息隐藏量大于传统算法,隐藏效果较好,可以满足文件隐秘传输需要,具有广阔的应用前景.

According to the characteristics of word document,this paper presents information hiding algorithm embedding secret message to word document by changing character scaling.It is showed that it is a simple algbrithm to achieve the goal of embedding secret text with larger information hidden capacity than traditional algorithm.It has a promising prospect of wide use in the fields of file transmitting in a secret way.
