Bayesian network-based trust model

We propose a Bayesian network-based trust model. Since trust is multifaceted, 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 a combination of multiple aspects. Bayesian networks provide a flexible method to present differentiated trust and combine different aspects of trust. A Bayesian network-based trust model is presented for a file sharing peer-to-peer application.
