Enabling Trustworthy Service Evaluation in Service-Oriented Mobile Social Networks
In this paper, the authors propose a Trustworthy Service Evaluation (TSE) system to enable users to share service reviews in Service-oriented Mobile Social Networks (S-MSNs). Each service provider independently maintains a TSE for itself, which collects and stores users' reviews about its services without requiring any third trusted authority. The service reviews can then be made available to interested users in making wise service selection decisions. They identify three unique service review attacks, i.e., link ability, rejection, and modification attacks, and develop sophisticated security mechanisms for the TSE to deal with these attacks.
