In this paper, a framework named SMARXO is proposed to address the security issues in multimedia applications by adopting RBAC (Role-Based Access Control), XML, and Object-Relational Databases. Compared with the other existing security models or projects, SMARXO can deal with more intricate situations. First, the image object-level security and video scene/shot-level security can be easily achieved. Second, the temporal constrains and IP address restrictions are modeled for the access control purpose. Finally, XML queries can be performed such that the administrators can proficiently retrieve useful information from the security roles and policies.
