MP3; audio compression; watermarking; multimedia encryption

The impetus for the work presented in this paper arose from the need to enable Internet-based secure audio delivery and protection of digitized music against illegal distribution. Approach described here, provides protection for widely accepted, MPEG-1 Layer-3 audio encoding format, although it can easily be applied to any other Perceptual Audio Coding (PAC) standard. During the process of MP3 encoding, selective, content-based security features are added to the stream in order to decouple and protect individual layers of audio quality while introducing minimal processing overhead and maintaining audio format.
In addition to quality-layered protection, we propose simultaneous use of our audio watermarking technology for a complete solution in network-based secure audio delivery and copyright protection.
