A Trust Evaluating Model Based on Reputation with Multifactor for P2P E-Commerce

Trust plays an important role in the development and implementation of P2P e-commerce systems. This paper proposes a novel Trust Evaluating Model Based on Reputation with Multifactor. By introducing many comprehensive trust factors in computing trust level and improving the computing methods of the local reputation and global reputation, this model can not only accurately reflect the node's trust level, but also reduce the time complexity in computing trust level. Experimental results show that the trust model can improve the rate of successful trading compared with the existing trust models, and can be effectively applied to the P2P e-commerce system.
