In this paper, the authors are proposing a new steganography method to hide any encrypted secret message in multiple steps. The secret message is encrypted using TTJSA algorithm. The authors embed this encrypted message inside one known image or audio file using 4-th bit from LSB substitution method. They again encrypt the embedded cover file using TTJSA algorithm. Finally embed this encrypted cover file in final known cover file which may be some image or audio file. In the present method the authors used data hiding and encryption in two steps to make the entire steganography method almost unbreakable.
