A Web-based Multilayer Access Control Model for Multimedia Applications in MPEG-7
This paper presents a Criterion-Based Role-Based Access Control model in which secure permissions (SP), secure operations (SOp), secure objects (SOb), and secure users (SU) are introduced. The security criterion expressions (SCE) embedded in SOb work as locks and the common elements of the security criterion subsets (SCSS) in SOp and SU work as keys. To support web-based applications, the remote secure user-role assignment is done based on user’s digital credential(s), and Compact-SecureRole-SCSS cookies are adopted to simplify the subsequent transactions. The multilayer access control is achieved by actuating locks with the relevant keys. The proposed model, an extension of traditional RBAC, efficiently supports both multilayer access control and non-multilayer access control on the web.
