SFCS-broker: Supporting feedback credibility brokering service for multiple clouds environments

Abstract

Due to the widespread of multiple clouds computing, the demand has increased for trust and credibility systems. In this paper, we present a SFCSBroker (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.
