Cloud computing presents new security and privacy challenges to control access to multi-tenant applications in the cloud. However, this solution has more challenges once the number of access control list (ACL) increases in the cloud, such as efficiency of policy resolution, multi-tenancy and data isolation. To address these limitations, this paper describes a fine-grained data-level access control model (FDACM) suitable for multi-tenant applications where role-based and data-based access control are both supported. Lightweight expressions are proposed to present complicated policy rules in our solution. Moreover, we discuss the most important part of FDACM in detail: query privilege model and decision privilege model. Furthermore, we also propose the architecture and authorization procedure which implements these two models. Some technical implementation details together with the performance results from the prototype are provided. Finally, a case study of FDACM is illustrated to evaluate the effect of the application in practice.
