Cloud computing is presently operating under its expected capacity, mainly because of the scarcity of trust between data owners and storage service providers. Therefore, establishing trust for cloud customers and providers has become an important issue in cloud computing environment. In the paper we present a novel trust management method (TrustSocieties), our attempt at addressing this trust issue through the use of information visualization. TrustSocieties is a visual method for graphical representation of entity trust relationships in cloud computing. The proposed method can assist cloud computing entities to make good trust decisions. The main contribution of this paper is to provide a visualization trust modeling method to user and improve his or her security situational awareness in the cloud computing environments. The experimental analysis shows that the proposed method gives a better understanding of the trust making process, and facilitates accurate and fair assessment of the service reputations. Our analysis shows a significant improvement in trust assignment accuracy for our technique in comparison to manual trust assignment. Our work appears to be the first attempt to research the visualization method of trust management for cloud computing.
