A multi-factor trust management system based on confidence in M-commerce environment

Trust plays an important role in the development and profitability of users in mobile commerce systems. In order to estimate the amount of trust, the variety of trust management systems have been proposed and implemented. One of the main challenges facing these systems is the types of attacks that threaten them and their impact on trust evaluation. In this paper, we studied four important attacks including new comer, Sybil, on-off and reputation squeeze and also propose a multi-factor trust management system based on confidence. The proposed model is simulated and results show that mean absolute error (MAE) is decreased.
