MP3Stego will hide information in MP3 files during the compression process. The

data is first compressed, encrypted and then data hidden in the MP3 bit stream.

Although MP3Stego has been written with steganographic applications in mind it

might be used as a watermarking system for MP3 files. Any opponent can

uncompress the bit stream and recompress it this will delete the hidden

information -- actually this is the only attack we know yet -- but at the

expense of severe quality loss.-MP3Stego will hide information in MP3 files during the compression process. The
