Abstract :
In this paper a novel data hiding scheme for MPEG compressed audio is proposed. It exploits wet paper codes as the communication channel and hides data directly in the MPEG audio bit stream by modifying the MPEG audio quantization process. It is applicable to all three layers of MPEG audio. Experimental results show that the proposed method is sustainable against transcoding and re-encoding without degrading the audio quality or increasing the file size
