语言隐写术作为文本隐写术的一种方法，正在成为一个热点。为了研究中文文本的语言隐写术，利用现有的中文信息处理技术，提出了一种中文语言隐写算法。该算法基于同一单词的同义词和变体形式的替换。此外，为了减少周围词与替换词之间的相互作用，利用汉语词法分析的消歧功能考虑句子的上下文窗口。实验结果表明，该算法取得了良好的效果，具有不可感知性、一定的信息承载能力和抗隐写分析的性能。
Linguistic steganography, as a method of text steganography, is becoming a hot spot. To investigate the linguistic steganography for Chinese text, a Chinese linguistic steganography algorithm is presented by utilizing the existing Chinese information processing techniques. The algorithm is based on the substitution of synonyms and variant forms of the same word. Furthermore, in order to decrease the interaction between the surrounding words and the substituted word, the contextual window of sentence is taken into account by using the disambiguation function of Chinese lexical analysis. Experimental results show that the algorithm can achieve a good result with the imperceptibility, a degree of information-carrying capacity and the performance of resistant to steganalysis.
