Personal Data Access Based on Trust Assessment in Mobile Social Networking
Zheng Yan, Xueyun Li, Raimo Kantola · 2014
Trustworthy personal data access control at a semi-trusted or distrusted Cloud Service Provider (CSP) is a practical issue although cloud computing has widely developed. Many existing solutions suffer from high computation and communication costs, and are impractical to deploy in reality due to usability issue. With the rapid growth and popularity of mobile social networking, trust relationships in different contexts can be assessed based on mobile social networking activities, behaviors and experiences. Obviously, such trust cues extracted from social networking are helpful in automatically managing personal data access at the cloud with sound usability. In this paper, we propose a scheme to secure personal data access at CSP according to trust assessed in mobile social networking. Security and performance evaluations show the efficiency and effectiveness of our scheme for practical adoption.
