Abstract: Traditional steganography scheme based on text is achieved by embedding blanks and tabs at the back of every row. These schemes have many disadvantages in security and efficiency, ex. they can easily be detected and attacked. This paper analyzes the structure and syntax of the text files and proposes a new and more secure steganography method. It achieves the aim of hiding secret information in text files by replacing thesaurus. Experiments and analysis prove that it is a method with high efficiency and security.
