A Survey Study on Reputation-based Trust Mechanisms in Service-Oriented Computing

ABSTRACT – The Reputation-Based Trust mechanism (RBT) helps a service assess the trustworthiness of offered services, based on the feedback obtained from their users. A key challenge to apply the RBT is to prevent the cheating behavior of users when they provide recommendations-- they might give unfair ratings to benefit themselves. This survey describes the research communities that are making efforts to solve the problems of the RBT in Service-Oriented Computing (SOC) domain. A summary of findings is then discussed to position the trends and directions of future studies. The survey can be used as a reference guide in a hope to make trust-based service systems more reliable and scalable
