An algorithm based on shift conversion is proposed combining with the characteristic of Chinese grammar.A method based on chinese mathematical expression is presented by converting Chinese text into bit string.Then,shift conversion rules are selected by utilizing transform grammar based on case grammar that Chinese philologist proposed.The secret information is embedded by modifying the order of words in the sentence according to the shift conversion rules.The experimental results show that the method can achieve a degree of information-carrying capacity and a better result with the imperceptibility.
