SRBAC: A Spatial Role-Based Access Control Model for Mobile Systems
نویسندگان
چکیده
Role-based access control models are receiving increasing attention as a recent generalized approach to access control. In mobile computing environments (that offers location based services), availability of roles and permissions may depend on users location. To cope with the spatial requirements, we extend the existing RBAC model and propose a Spatial Role-based Access Control (SRBAC) model that utilize location information in security policy definitions.

The rapid growth of mobile phone technology and its combination with various technologies like GPS has added location context to social networks and has led to the formation of location-based social networks. In social networking sites, recommender systems are used to recommend points of interest (POIs) to users. Traditional recommender systems, such as film and book recommendations, have a lon...
متن کاملA semantic-aware role-based access control model for pervasive computing environments
Access control in open and dynamic Pervasive Computing Environments (PCEs) is a very complex mechanism and encompasses various new requirements. In fact, in such environments, context information should be used in access control decision process; however, it is not applicable to gather all context information completely and accurately all the time. Thus, a suitable access control model for PCEs...

متن کاملA context-sensitive dynamic role-based access control model for pervasive computing environments
Resources and services are accessible in pervasive computing environments from anywhere and at any time. Also, due to ever-changing nature of such environments, the identity of users is unknown. However, users must be able to access the required resources based on their contexts. These and other similar complexities necessitate dynamic and context-aware access control models for such environmen...
