Abstract
Due to the widespread of multiple clouds computing, the demand has increased for trust and credibility systems. In this paper, we present a SFCS-Broker (Supporting Feedback Credibility Brokering Service for Multiple Clouds Environments) to make an efficient matching between users and providers by monitoring the real-time behavior, collecting users' feedback and ensuring credibility of the provided feedback. The proposed SFCS-Broker scheme allows balancing between delay and ratio of the calculated credibility. Additionally, the experimental results show that SFCS-Broker successfully detects various models of malicious users.
