Abstract:

Audio compression history detection is an important part of audio forensics,which is important to detect whether audio has been tampered or forged.An algorithm of AAC audio compression history detection was presented by using the transition probability differences of scale factors as the discriminative feature.Experimental results demonstrate that the proposed method can distinguish the single,double and triple compressed AAC audios effectively,and from the low-bite-rate to high-bit-rate,the average classification accuracy achieves 99.75%,the same-bit-rate detection accuracy achieves 97.28%.In addition,the results of comparison experiments show that the proposed algorithm outperforms the state-of-the-art algorithm.

Key words: AAC audio, compression history, scale factor, transfer probability
