Advanced Steganographic Approach for Hiding Encrypted Secret Message in LSB, LSB+1, LSB+2 and LSB+3 Bits in Non Standard Cover Files
In digital steganography normally image, audio or video files are the standard cover files or the host files for embedding secret message such as text, image, audio or video. Nath et al. explored the standard method for hiding secret message inside standard cover files such as image, audio or video files. In this paper, the authors have shown how they can hide secret message in encrypted form in some non standard cover files such as .exe, .com, .pdf, .doc, .xls, .mdb, .ppt files. However, the size of the secret message must be very small in comparison to cover file.
