In this paper, we analyze existing text-based steganography techniques, and propose an efficient information hiding algorithm for text based on substituted conception. In this algorithm, candidate units are replaced by similar conception, including synonym, homonym or special character. An improved encoding algorithm is also proposed which is not only enhances the robustness, but also enlarges the capacity of secret message. It is proved by the experiments that the proposed algorithm has good performances both in security and capacity.
In REF , text-based steganography is proposed in which applicant data are substituted by similar outset, including alternative word (synonym), homonym or exceptional character.
