A-COLD: Access Control of Web OLAP over Multi-data Warehouse

This paper proposes the design and development framework of collaborative access control for OLAP queries spanning over multi-data warehouse (DW). The approach is based on PKI Authentication and Privilege Management Infrastructure (PMI); it presents a binding model of DW user identification and privilege of fact and dimensional access. To integrate several security policies from DWs, we employ the XACML policy integration to serve interoperation and authorization management. In our approach, we apply the multi-agent system to automate flexible and effective management of user authentication, role delegation as well as system accountability. Finally, the implementation details of the prototype A-Cold (Access Control of web-OLAP over multiple DWs) is presented to demonstrate our research idea.
