A trust evaluation model and algorithm based on network behavior detection

Evaluation of trustworthiness of participating entities is an important method to stimulate collaboration in open networks. This paper presents a network behavior based trust evaluation model (NBTEM), which calculate trust value based on not only transaction feedback but also network behavior detection. The paper describes the framework and workflow of NBTEM, introduces an trust value evaluation algorithms, discusses the method of trust measurement and trust value comprehensive calculation. The example analysis and experimental results show that the NBTEM makes trust evaluation more reliably and effectively than the traditional reputation systems based on only transaction feedback.
