A novel trust model based on D-S evidence reasoning and Fuzzy Cognitive time Map

This paper presented an approach for trust computing using Fuzzy Cognitive Map and D-S evidence reasoning theory. As fuzzy inference can deal with variable dependencies in the system by decoupling dependable variables, FCM provides an efficient way to trust deducing, and also the difficulty and complexity of trust computing. The approach of DS evidence overcomes the problem of over-precision.
