Abstract :
We present a new, principled steganalytic approach to estimate the length of messages, if any, hidden in the least significant bits of digitized continuous signals such as images and audio. Our estimates of LSB-embedded messages are based on some intrinsic statistical properties of sample pairs drawn from the signal. We also give bounds on the estimation errors. Furthermore, possible attacks on our new steganalytic approach and our countermeasures are also discussed.
