Abstract

Study of the reputation scaling module

Author(s): Jiang He

The RSM (Reputation Scaling Module) was the heart of the TMS (Trust Management System). The RSM was responsible for accepting an associate’s behavior history and calculating a RI (Reputation Index). The RI was aweighted estimation of the associate’s trustworthiness and formed the basis for the TMS’s trust decision.Without the RSM, the TMS would not have had the ability to process an associate’s behavior history and, thus, have been unable to make any sort of trustworthiness decision. This paper explains the basic trust model that the RSM implemented and describes the method of how behavior observations were transformed into weighted FIs.
