RESUMO

Audio steganalysis method based on "negative resonance phenomenon" is proposed. Differences between the first and higher order statistics before and after "control stego transformation" for the test signal and its linear prediction error are used to distinguish empty and stego signals. The method includes the SVM binary classifier. Test results show the effectiveness of the method of detecting Hide4PGP stego signals when their payloads are more than 20 %.
