“…A typical approach to realize a secure content delivery in P2P environment is to use Digital Right Management (DRM) technology [8], [15], [19], [20]. DRM controls the usage and the redistribution of digital contents using several key technologies such as public-key cryptography.…”

SUMMARYRecently Peer-to-Peer Content Delivery Networks (P2P CDNs) have attracted considerable attention as a cost-effective way to disseminate digital contents to paid users in a scalable and dependable manner. However, due to its peer-to-peer nature, it faces threat from "colluders" who paid for the contents but illegally share them with unauthorized peers. This means that the detection of colluders is a crucial task for P2P CDNs to preserve the right of contents holders and paid users. In this paper, we propose two colluder detection schemes for P2P CDNs. The first scheme is based on the reputation collected from all peers participating in the network and the second scheme improves the quality of colluder identification by using a technique which is well known in the field of system level diagnosis. The performance of the schemes is evaluated by simulation. The simulation results indicate that even when 10% of authorized peers are colluders, our schemes identify all colluders without causing misidentifications.

“…Although many online resources currently being shared over a network are free or open access (e.g., YouTube and BitTorrent), there is a strong demand to distribute a given media file only to paid users in a secure and cost-effective manner. Recently, Peer-to-Peer Content Delivery Networks (P2P CDNs) have attracted considerable attention as a cost-effective way to deliver large media files to many users in a given computer network [12], [15], [16]. Content delivery in a P2P CDN is invoked by the owner of a media file by pushing a copy of the file to the P2P overlay, and once a copy is available in the overlay, it will be delivered to the authorized recipients by repeating local communication among nearby peers in the P2P overlay, where the authorized peer is a peer who paid for the content and received an authority from the distribution agent (DA) of the P2P CDN.…”

Abstract:The objective of Peer-to-Peer Content Delivery Networks is to deliver copyrighted contents to paid clients in an efficient and secure manner. To protect such contents from being distributed to unauthorized peers, Lou and Hwang proposed a proactive content poisoning scheme to restrain an illegal download conducted by unauthorized peers, and a scheme to identify colluders who illegally leak the contents to such unauthorized peers. In this paper, we propose three schemes which extend the Lou and Hwang's colluder detection scheme in two directions. The first direction is to introduce an intensive probing to check suspected peers, and the second direction is to adopt a reputation system to select reliable (non-colluder) peers as a decoy. The performance of the resulting scheme is evaluated by simulation. The result of simulations indicates that the proposed schemes detect all colluders about 30% earlier on average than the original scheme while keeping the accuracy of the colluder detection at medium collusion rate.

“…P2P suitable DRM systems [7][8][9][10][11] can be categorized into four types, i.e., server-client based architecture, distributed architecture, semi-distributed architecture and super-node based architecture. In server-client based architecture, P2P networks are used only as the channels of content distribution, while all the licenses are issued by the DRM server.…”

Service technology is slowly evolving to be a promising technology for developing applications in open, loosely coupled and distributed computing environments, e.g., in mobile commerce (m-commerce). Services technology can shield the heterogeneous platforms and is suitable for m-commerce applications. Peer-to-Peer (P2P) technology becomes more and more popular for mobile commerce applications. For secure media distribution in m-commerce applications, the security and P2P rights management become more and more urgent. New schemas and architectures for secure P2P based m-commerce applications, which are expected to function automatically or semi-automatically, are expected. In this paper, a secure media service system is presented, which can trace illegal distributors in m-commerce applications. In this scheme, the decryption operation and fingerprint embedding operation are combined together, which avoids the leakage of clear media content in mobile transfer. Additionally, these operations are implemented by the peer, which makes the scheme compliant with existing Peer-to-Peer Digital Rights Management (DRM) systems and very proper for secure media distribution in m-commerce applications. The architectures and modes of secure media distribution in m-commerce environment are presented and discussed.
