Semantic steganograhpy is a method using texts to hiding secret information, which embeds message into texts at the level of linguistic understanding. This paper studies the semantic steganography method, and analyzes the statistical features to search the differences between stego-texts and natural texts by modeling the latter. And a steganalysis method is designed based on the distribution of characters according to the differences. The method is easy to achieve, and experiments prove the efficiency and reliability of the method
