“We propose a decentralized privacy-preserving approach to spam filtering. Our solution exploits robust digests to identify messages that are a slight variation of one another and a peer-to-peer architecture between mail servers to collaboratively share knowledge about spam.”

Cornelli, Fabrizio, Damiani, Ernesto, Vimercati, Sabrina De Capitani di, Paraboschi, Stefano and Samarati, Pierangela (2002): Choosing reputable servents in a P2P network. In: Proceedings of the 2002 International Conference on the World Wide Web 2002. pp. 376-386. Available online

“Peer-to-peer information sharing environments are increasingly gaining acceptance on the Internet as they provide an infrastructure in which the desired information can be located and downloaded while preserving the anonymity of both requestors and providers. As recent experience with P2P environments such as Gnutella shows, anonymity opens the door to possible misuses and abuses by resource providers exploiting the network as a way to spread tampered with resources, including malicious programs, such as Trojan Horses and viruses. In this paper we propose an approach to P2P security where servents can keep track, and share with others, information about the reputation of their peers. Reputation sharing is based on a distributed polling algorithm by which resource requestors can assess the reliability of perspective providers before initiating the download. The approach nicely complements the existing P2P protocols and has a limited impact on current implementations. Furthermore, it keeps the current level of anonymity of requestors and providers, as well as that of the parties sharing their view on others' reputations.”

Bertino, Elisa, Jajodia, Sushil and Samarati, Pierangela (1999): A flexible authorization mechanism for relational data management systems. In ACM Transactions on Information Systems, 17 (2) pp. 101-140

“In this article, we present an authorization model that can be used to express a number of discretionary access control policies for relational data management systems. The model permits both positive and negative authorizations and supports exceptions at the same time. The model is flexible in that the users can specify, for each authorization they grant, whether the authorization can allow for exceptions or whether it must be strongly obeyed. It provides authorization management for groups with exceptions at any level of the group hierarchy, and temporary suspension of authorizations. The model supports ownership together with decentralized administration of authorizations. Administrative privileges can also be restricted so that owners retain control over their tables.”
