Lossless data-compression ratios are computed from the testing signals and their reference versions and used as features for the classifier design. Additionally, we propose to extract additional features from different energy parts of each tested audio signal to retrieve more informative data and enhance the classifier capability. Support Vector Machine (SVM) is employed to discriminate between the cover- and the stego-audio signals. Experimental results show that our method performs very well and achieves very good detection rates of stego-audio signals produced by S-tools4, Steghide and Hide4PGP. © 2012 Springer-Verlag.enLicense to reuse abstract has been provided by Springer Nature and Copyright Clearance Center.Active speech levelAudio signalAudio steganalysisBlind steganalysisClassifier designDetection ratesLosslessTesting signalAudio signal processingSteganographySupport vector machinesData compressionConference PaperCopyright : © 2012 Springer-Verlag
