pFusion: A P2P Architecture for Internet-Scale Content-Based Search and Retrieval

Abstract”The emerging Peer-to-Peer (P2P) model has become a very powerful and attractive paradigm for developing Internet-scale systems for sharing resources, including files and documents. The distributed nature of these systems, where nodes are typically located across different networks and domains, inherently hinders the efficient retrieval of information. In this paper, we consider the effects of topologically aware overlay construction techniques o ....etc

Networked computer systems are rapidly growing in importance as the medium of choice for the storage and exchange of information. However, current systems afford little privacy to their users, and typically store any given data item in only one or a few fixed places, creating a central point of failure. Because of a continued desire among individuals to protect the privacy of their authorship or readership of various types of sensitive information, and the undesirability of central points of failure which can be attacked by opponents wishing t ....etc

Collusive piracy is the main source of intellectual property violations within the boundary of a P2P network. Paid clients (colluders) may illegally share copyrighted content files with unpaid clients (pirates). Such online piracy has hindered the use of open P2P networks for commercial content delivery. We propose a proactive content poisoning scheme to stop colluders and pirates from alleged copyright infringements in P2P file sharing. The basic idea is to detect pirates timely with identity-based signatures and time stamped tokens. The schem ....etc

Security Issues of P2P Networks

Abstract
P2P applications introduce a whole new series of security issues, security within the virtual P2P networks themselves and security with respect to the environments they ride on. P2P technology can undermine network security and can leave computing devices open to threats ranging from violations of intellectual property laws, virus ....etc
