While providing services to stakeholders, service software can be exploited by potentially untrustworthy users. Given that, it is necessary to monitor the trust relationships between service providers and requestors for potential vulnerabilities they may invite to the total system. In this paper, we propose an Automatic Trust Monitoring algorithm called ATM based on the specification of trust relationships in trust scenarios and the quantification of the relationships through trust calculation schemes. Trust rules are generated from the trust scenarios ready to be deployed at run-time. A service requestor is penalized for the violation of a trust rule and rewarded for no such violation. This analysis facilitates the quantification of the trustworthiness of service requestors and the accuracy of the recommendations from other service providers that can be used to make dynamic decisions on the corresponding requestors. The monitor is implemented in a prototype file sharing grid and evaluated using file sharing applications.
