| description.abstract | Steganography is used to hide the occurrence of communication. Discovering
and rendering useless such covert message is an art of steganalysis. The
importance of techniques that can reliably detect the presence of secret messages in
images is increasing as images can hide a large amount of malicious code that could
be activated by a small Trojan horse type of virus and also for tracking criminal activities
over Internet. This paper presents an improved blind steganalysis technique.
The proposed algorithm reduces the initial-bias, and estimates the LSB embedding
message ratios by constructing equations with the statistics of difference image histogram.
Experimental results show that this algorithm is more accurate and reliable
than the conventional difference image histogram method. It outperforms other powerful
steganalysis approaches for embedded ratio greater than 40% and comparable
with RS steganalysis technique for shorter hidden message length. | en |
