Context-aware Access Control in Pervasive Healthcare
نویسندگان
چکیده
Progress in mobile devices, wireless networks and context-aware technologies are bringing pervasive healthcare into reality. With the help of wireless PDAs and portable computers, people may enjoy high quality care from a well-orchestrated team of healthcare professionals in the comfort of their own homes. The main technical challenges include mobility, adaptability, privacy, access authorization, and resource awareness. This paper presents a rule-based approach to context-aware access control in pervasive healthcare. The system is designed to work on resource-limited mobile devices over a peer-to-peer wireless network. Dynamic access authorization is achieved in real time by actively collecting context information, integrating the appropriate access control rules, and performing logical inference on the mobile device. Performance evaluations of the prototype implementation show the efficiency of the proposed mechanism.

A 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...

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...
