A Secure Data Access Mechanism for Cloud Tenants

Abstract—As the future big data storage center for tenants, cloud computing has been a hot issue recently, it consists of many large datacenters which are usually geographically distributed and heterogeneous, secure data access from cloud computing platform is a big challenge for cloud tenants. In this paper, we present a secure data access mechanism based on identity-based encryption and biometric authentication for cloud tenants. We review briefly about identity-based encryption and biometric authentication firstly and then we proposed a data access mechanism for cloud tenants, the mechanism set double protection for confidential data of cloud tenants, encryption will make the tenants data secure against the peekers and biometric authentication will eliminate the maloperations over tenants data by root administrator in cloud service. We compared the proposed mechanism with other technology and schemes through comprehensive analysis and experiment data; the results show that the proposed data access mechanism is feasible and suitable for cloud tenants.
