Abstract

The false decision ratio in MMOGs is quite high because of the fixed parameter thresholds deployed in the cheating detection mechanism. This paper introduces the trust management into the cheating detection mechanism, and proposes a FuzzyTD algorithm. The algorithm updates player's reputation vector calculated from his history data of the game, and then adjusts the game parameter thresholds further. Therefore, the false decision ratio reduces. The simulation results show that the false decision ratio is much lower, and the performance is much better by introducing the FuzzyTD algorithm.
