“…Velastin and Lian [Velastin and Lian, 2010] assert that the content distribution based on watermarking would foster security in P2P content distribution systems. Tsolis et al [Tsolis et al, 2011] have proposed a P2P sharing system which not only allows digital content exchange but also supports copyright protection and management through watermarking technologies.…”

In this paper, we study several important issues that can be used to prevent pirated content propagation in BitTorrent (BT) Distributed Hash-Tables (DHT) networks. We design a system called PPBD to stop pirated content propagation by utilizing several attacking methods. First, the system can efficiently deal with massive concurrent connections to reduce bandwidth consumption, schedule peers to cooperate and optimize the protection methods according to clients. Second, we construct two mathematical models for BT DHT attacks, and we theoretically analyze the system performance. Third, we take into account some countermeasures of different BT clients and make corresponding optimizations of our PPBD system. Our realworld experiments show that: (1) our system can extend the download duration at least three times by the fake-block attacking method and it is more effective in a small swarm; (2) DHT index poison and routing pollution methods can limit the sharing swarm to a small swarm.

SummaryIllegal sharing of copyrighted materials in peer‐to‐peer (P2P) networks has become a serious threat to the content industries. Despite many copyright‐protected P2P systems that have been designed to prevent piracy, the user authentication–based approaches face the challenge of collusion attacks and the encryption‐based approaches may be vulnerable to poisoning attacks. Observing these, in this paper, we present a novel copyright‐protected content delivery scheme (CPP) for P2P file‐sharing networks based on piece‐level stochastic encryption. In CPP, peers must pay for decryption key sequences before accessing to the plaintext content. For each peer, the sequence of the decryption keys is different from others, so the unauthorized peers could not access the content even if some colluders share their keys. Modified piece with hash enable peers to check the correctness of each piece after downloading, preventing the propagation of poisoned pieces. There is neither massive state maintenance nor frequent user authentication during the download process. Peers purchase after downloading, protecting their benefits when quitting the system before paying. Analysis and experiments show that CPP is suitable for delivering large files, and it is resilience to collusion attacks and poisoning attacks.
