Research And Application On Spatial Access Control Model Based On UCON

Securing access to data in location-based services and mobile applications pose interesting security requirements against spatially aware access control systems.And also has a special request:The permit of user's right is decided by the user's geographical location. Therefore,the spatial information in the access control model is a key parameter of the context.However,traditional access control models,are typical of non-context-sensitive,such as Mandatory Access Control,Discretionary Access Control,Role-Based Access Control,and they need complex and required certification static infrastructure.Therefore,do not be able to meet the requirements of spatial database.In order to meet the above requirements,An access control model is nedd.User location in the process of change in real-time required for the system,the object of ongoing property updates.And the continued authorize of the property is the main features of the UCON model,so for the use of the access control model is the most suitable choice.In the space environment,the user's access request,as well as access to resources by users of the space region where the current constraints.Only when the user's current location in their space domain in order to be granted permission to operate on the object or the resources to continue his visit.Authorized access control system in decision-making must be based on the object and the location of the user's space to grant/cancellation of user privileges or the termination of the ongoing visit. However,the existing UCON model applied to spatial data access control must be improved,increased security features of spatial data support.In order to adapt to the spatial database in which user rights and their spatial relationship between the mapping.In this paper,spatial database management system as a platform to study the spatial characteristics of support for access control model used in GEO-UCON features to enhance the properties of space UCON model description of the ability to enrich and improve the safety of the theory of spatial database for the military, banking,securities and other information-sensitive industry set up a more rigorous system of information security protection to lay a theoretical basis.
