The development of information technology has eased the medical services and provided the electronic health service in a way that a doctor can keep the records of patients in an information system and be informed of changes of status of patients, and make decisions promptly. However, there are increasing challenges over the privacy of patients due to the exposition of clinic information patients to ubiquitous networks. This paper introduces a framework for authentication and authorization in e-health services. It aims to build the architecture for authentication and authorisation within an e-health service system. The architecture will help to build a secure and privacy-protection e-health service system. The authors hope that understanding the underlying framework will not only inform researchers of a better design for e-health service, but also assist e-health systems developers in the understanding of intricate constructions within authentication and authorisation. Further, our paper highlights the importance of protecting the privacy of medical records of patients in terms of information privacy.
