  Article: Natural Language Information Hiding Based on Chinese Mathematical Expression

  [show abstract] [hide abstract]
  ABSTRACT: A novel method of natural language information hiding is presented based on Chinese mathematical expression. The method can convert Chinese text into bit string by using the thought of Chinese mathematical expression, and then embed the secret message into the text by utilizing the replacement of synonyms, variant forms of the same word, the adding or deleting of the empty words, and the shift conversion of the sentence. Experimental results show that the method can achieve a faster conversion of the text into the binary string, a better degree of information-carrying capacity and a better result with the imperceptibility.

  Article: Natural Language Watermarking Using Chinese Syntactic Transformations

  Wang Hong, Sun Xingming, Liu Yuling, Liu Yongping
  [show abstract] [hide abstract]
  ABSTRACT: In this study, a novel natural language watermarking scheme of Chinese texts based on syntactic transformations is proposed. In the proposed scheme, the so-called sentence weight defined in the study is used to carry the watermark bit. During the embedding process, the transformable sentences are first grouped and then their sequence is permuted to enhance the imperceptibility of watermark bit hiding positions. To improve watermarking reliability and capacity, error correcting coding is also applied.

• Conference Proceeding: An Efficient Linguistic Steganography for Chinese Text

  ABSTRACT: 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.
