Abstract:
Steganalysis is the art and science of
detecting messages hidden using steganography.
This paper proposes steganalysis of audio signal
using Independent Component Analysis. A
detection method is used for detecting hidden
message in compressed audio files produced by
MP3Stego. Steganography can be successfully
detected during the Principle Component
Analysis (PCA) whitening stage. A nonlinear
robust batch ICA algorithm, which is able to
efficiently extract various temporally correlated
sources from their observed linear mixture are
used for blind steganography extraction.
