A mobile location-based with time-constraint RBAC associated database management model

摘要

Securing access to data in location-based and temporal services and mobile applications requires the definition of temporal and spatial access-control systems. One of the access- control techniques is Role-based Access Control (RBAC). To cope with the requirements of both location-based and temporal constraint in wireless associated database computing environment, we propose a Mobile Location-based with Time-constraint RBAC (MLT-RBAC) associated database management model. In the this model, temporal-period and spatial-location-based entities will be allowed to access wireless associated database (WAD) system after passing the authentication phase via serving WAD server. In this paper, all definitions, such as the permissions of objects, user positions, and geographically bounded roles have re-proposed for the new applications in WAD system. Therefore, we present the relations of associated RH, location-based and temporal SSD as well as DSD constraints in the MLT-RBAC model.
