Yang Yi-xianand · Acta Scientiarum Naturalium Universitatis Sunyatseni · 2004
This paper presents an audio hiding algorithm on GSM mobile communication system. The hiding capacity of the algorithm is 50 bit per second. After a lot of experiments, it was proved that this algorithm has strong robustness to many attacks such as GSM,ADPCM compression and filter. The average SNR of the middle speech is close to 35 db, therefore the imperceptibility will be ensured. Moreover the algorithm is based on blind_detection,it is simple and effective.
