Abstract :
In multimedia content protection, encryption is often used to limit the access to authorized users. The authors concentrate on audio content protection. The encryption can be integrated with source encoding to generate the encrypted bitstream or directly scramble the compressed bitstream. We investigate the MP3 format music protection. Several scrambling algorithms in raw data domain and MP3 compression domain are presented for various application scenarios
