Abstract:
In this paper, we propose a peer-to-peer (P2P) content distribution system that allows the efficient distribution of large-sized multimedia contents while preserving the security and privacy of content providers (merchants) and end users (buyers), respectively. However, the privacy of a buyer can be revoked as soon as he/she is found guilty of copyright violation. A payment protocol is also proposed that provides a secure payment mechanism, where personal information and order information cannot be exposed to an unauthorized third party. In addition, a reputation-based system is introduced for the selection of the proxy peers required for secure delivery of the fingerprinted content from the merchant to the buyer. The paper presents a thorough security analysis of the system against several security compromising attacks.
