基于汉字数学表达式的无载体文本隐写方法

A Method of Text Steganography Without Carrier Based on Mathematical Expressions of Chinese Characters

针对现有的以文本为载体的隐写术在隐蔽性、鲁棒性、隐写容量等方面存在的问题,提出了一种基于汉字数学表达式的无载体文本隐藏方法,首先应用汉字笔顺分类或者载体文本中不重复的汉字对载体文本进行编码,然后使用汉字数学表达式对含有编码信息的汉字的位置进行描述,从而使得接收方可以进行完整的秘密信息的提取。这种方法中的文本载体没有经过任何的改动,所以其隐蔽性和鲁棒性方面较以前的方法有很大改进,并且在隐藏容量方面也有较高的优势。

Because of concealment,robustness,and steganographic capacity existing in the text-based steganography.An unsupported text hiding method based on Chinese character mathematical expression is proposed.Firstly,the Chinese character is encoded by the Chinese character stroke classification or the non-repeating Chinese characters in the carrier text,and then the position of the Chinese character containing the coding information is performed using the Chinese character mathematical expression.Description,the receiver can extract the complete secret information.The text carrier in this method has not been changed,so its concealment and robustness are greatly improved compared with the previous methods,and it also has a higher advantage in hiding capacity.
