Trust is widely recognized as an essential factor for the continual development of business to customer electronic commerce (B2C EC). Many trust models have been developed, however, most are subjective and do not take into account the vagueness and ambiguity of EC trust and the customers’ intuitions and experience when conducting online transactions. In this article, we develop a fuzzy trust mo...

Trust management is one of the drawbacks in Peer-toPeer (P2P) system. Lack of centralized control makes it difficult to control the behavior of the peers. Reputation system is one approach to provide trust assessment in P2P system. In this paper, we use fuzzy logic to model trust in a P2P environment. Our trust model combines first-hand (direct experience) and second-hand (reputation) informati...

Trust is situation-specific and the trust judgment problem with which the truster is confronted might be, in some ways, similar but not identical to some problems the truster has previously encountered. The truster then may draw information from these past experiences useful for the current situation. We present a knowledgeintensive and model-based case-based reasoning framework that supports t...

the aim of this study was to identify the model of the effect of brand communities based on social media on value creation practices, brand trust and brand loyalty. the statistical population consisted of all members of sport brand communities of social media in mazandaran province and 115 subjects were selected as the sample. for data collection, brand communities (laroche et al., 2012) questi...

In this paper, we propose a Bayesian network-based trust model. Since trust is multi-faceted, even in the same context, agents still need to develop differentiated trust in different aspects of other agents’ behaviors. The agent’s needs are different in different situations. Depending on the situation, an agent may need to consider its trust in a specific aspect of another agent’s capability or...

In this dissertation we study the security and survivability of wireless mobile network systems in two distinct threat models: the Byzantine threat model and the selfish node threat model. Wireless mobile networks are collections of self-organizing mobile nodes with dynamic topologies and have no fixed infrastructure. Because of their dynamic ad hoc nature, these networks are particularly vulne...

In this study, we drew from the existing online trust model to develop a specific model of online lending platform trust from the perspectives of cognition-based trust and affect-based trust. Trust between lenders and borrowers have been discussed a lot but there are no empirical studies focusing on trust toward lending platforms. The dearth of the relevant studies on this aspect indicates the ...

An evaluating mechanism-based cloud computing trust model is raised to aim at the issue of how the cloud service user selects credible cloud service supplier. The trust model constitutes an evaluating system about service behavior between cloud service supplier and cloud service user. After formalized evaluation about entity achieved, certain algorithm would be used to get the trust and trust v...

In this paper, we continue our line of research for defining an integrated framework for the specification and analysis of security and trust, aimed at providing the basis for the modeling and analysis of security and trust aspects of emergent dynamic coalitions (e.g., mobile ad hoc networks, peer to peer systems, web services). In particular, we consider two well-known languages: 1) the Role-b...
