ENHANCING LSB STEGANOGRAPHY AGAINST STEGANALYSIS ATTACKS USING COMBINATIONAL LSBS

摘要

This paper describes an enhanced approach for hiding secret messages in the spatial domain of digital cover images such that the resulting stego-images are robust to steganalysis attacks. Firstly, different methods of hiding in the Least Significant Bits (LSBs) are comparatively discussed including the Sequential and the Random algorithms. Then our approach is illustrated which uses a combination of LSBs to store large amounts of secret information while maintaining robustness against detection by steganalysis attacks. The results achieved are commensurate to those obtained using widely available stego tools.
