A Real-Time Mp3 Copyright Protection System for Mobile Terminals:Practicalissues

With the development of the Internet and mobile terminals, more and more pirate digital music resources are easily disseminated online. To prevent the illegal copies propagating among mobile devices and protect the right of content providers. In this paper, we designed a practical real-time mp3 Copyright Protection System(MCPS) for mobile terminals which is based on Client/Server model and contains three parts: security channel, server and client. In particular, we established a secure channel based on SSL(Secure Sockets Layer) protocol, defined an identity authentication procedure between the server and the client. In the server, we designed RC4 based encryption algorithm for frame header, and chaotic based watermarking algorithms for frame body, respectively. In the client, we designed a novel mp3 streamd ecoder, where, for each frame, frame header is decrypted, and the embedded information is extracted and compared with its IMEI to decide whether to decode or not. The practical experiments show that the system can effectively protect copyright for digital_music and is of great.
