PATROL: a comprehensive reputation-based trust model
TLDR

In this paper, we present PATROL, a general and comprehensive reputation-based trust model for distributed computing. The proposed model is an enhancement over our previous model, TRUMMAR, and aims at achieving a truly unique model that incorporates most concepts that are essential to determining trust-based decisions. Among the concepts upon which the trust model is based are reputation values, direct experiences, trust in the credibility of a host to give recommendations, decay of information with time based on a dynamic decay factor, first impressions, similarity, popularity, activity, cooperation between hosts, in addition to a hierarchy of host systems. The simulations performed on this model confirm its correctness and its adaptability to different environments and situations.read more

A reputation system for e-marketplaces based on pairwise comparison
TL;DR: This paper aims to solve four problems that are common to reputation systems in e-marketplaces, namely the subjectivity of ratings, inequality of transactions, multi-context reputation and dynamic behavior of users, by starting with the pairwise comparison and extending it to contests between users.

PeerTrust: supporting reputation-based trust for peer-to-peer electronic communities
TL;DR: PeerTrust is presented - a reputation-based trust supporting framework, which includes a coherent adaptive trust model for quantifying and comparing the trustworthiness of peers based on a transaction-based feedback system, and a decentralized implementation of such a model over a structured P2P network.

An evidential model of distributed reputation management
Bin Yu,Munindar P. Singh +1 more
TL;DR: This approach adapts the mathematical theory of evidence to represent and propagate the ratings that agents give to their correspondents and establishes that some important properties of trust are captured by it.

Trust and reputation model in peer-to-peer networks
Yao Wang,Julita Vassileva +1 more
TL;DR: A Bayesian network-based trust model and a method for building reputation based on recommendations in peer-to-peer networks are proposed and shown to outperforms the system where peers do not share recommendations with each other and that a differentiated trust adds to the performance in terms of percentage of successful interactions.

A Reputation-based trust management system for P2P networks
TL;DR: A reputation-based trust management protocol for P2P networks where users rate the reliability of parties they deal with, and share this information with their peers to establish trust among good peers as well as identifying the malicious ones.
