Authentication in E-Health Services

Abstract

E-health services are a modern technology that stores the health records of patients and allows medical practitioners to retrieve them remotely. E-health services have provided high-level availability and good support for medical services, but a secured authentication mechanism is vital for the protection of this sensitive information. The main concern for e-health services is that the information is transmitted through a public transmission medium and the existing authentication mechanism fails to secure the user identity and is vulnerable to different network attacks. The main aim of this paper is to provide a review of different types of authentication mechanisms used in e-health services along with their implemented technologies and provide an overall framework for future research. This report will compare and contrast the currently available authentication mechanisms of e-health services along with their data input, processing, outcome, and the recent technologies implemented in the system. Through this report, the reader will be able to gain an overview of all the existing authentication protocols based on their techniques, methods, and algorithms for improving the security of e-health services and to secure the patient data.
