The Neural Computation of Trust and Reputation
Humans learn to trust new partners by evaluating the outcomes of repeated interpersonal interactions. However, available prior information concerning the reputation of these partners may alter the way in which outcomes affect learning. This thesis combines for the first time behavioral, …

Adaptive trust and reputation system as a security service in group communications
… to multiple receivers. Owing to the multicasting and broadcasting nature, group communications are susceptible to various kinds of attacks. Though a number of proposals have been reported to secure group communications, provisioning security in group communications remains a critical and …

Trust and reputation in multi-modal sensor networks for marine environmental monitoring
Greater temporal and spatial sampling allows environmental processes and the well- being of our waterways to be monitored and characterised from previously unobtainable perspectives. It allows us to create models, make predictions and better manage our environments. New technologies are emerging in …

Computational models of trust and reputation : agents, evolutionary games, and social networks
Many recent studies of trust and reputation are made in the context of commercial reputation or rating systems for online communities. Most of these systems have been constructed without a formal rating model or much regard for our sociological understanding of these concepts. We first provide a …

Quantifying Trust and Reputation for Defense against Adversaries in Multi-Channel Dynamic Spectrum Access Networks
… from multiple cognitive radios are fused as stand-alone observations are prone to errors due to wireless channel characteristics. Such dependence on cooperative spectrum sensing is vulnerable to attacks such as Secondary Spectrum Data Falsification (SSDF) attacks when multiple malicious or …

Reputation in Multi Agent Systems and the Incentives to Provide Feedback
… transactions are likely to be subject to fraud and cheating. If such systems use computerized rational agents to negotiate and execute transactions, mechanisms that lead to favorable outcomes for all parties instead of giving rise to defective behavior are necessary to make the system work: …

A synergistic reputation-policy based trust model for Grid resource selection
In the context of Grid computing, reputation-based trust management systems are playing an increasingly important role for supporting coordinated resource sharing and ensuring provision of quality of service. However, the existing Grid reputation-based trust management systems are considered …

Probabilistic trust models in network security
… motivation of using the notion of probabilistic trust as an approach to security sensitive decision making in modern open and global computing systems. In such systems any principal A uses the outcomes of past interactions with another principal B to construct a probabilistic model approximating …

Water development programs in India
… cooperation (DC) led by conventional bi- and multilateral donors has been joined by a large number of small, private or public-private donors. This pluralism of actors raises questions as to whether or not these new donors are able to implement projects more or less effectively than their …

The role of attention-deficit/hyperactivity disorder and parental misperceptions in risk for child physical abuse
… There may be unwanted calls from legitimate and known people too. In this case, the unwantedness depends on social proximity of the communicating parties. For detecting these unwanted calls, I propose a framework that analyzes incoming calls for unwanted behavior. The framework includes a …
