RT Journal Article ID 090a7c9b77f0efdf A1 Koshkina, Natalya V. T1 Detection of Hidden Messages Embedded in Audio Signals by Hide4PGP JF Journal of Automation and Information Sciences JO JAI(S) YR 2013 FD 2013-07-23 VO 45 IS 5 SP 75 OP 81 AB 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 %.
