Tele-care medical information systems security techniques: A critical review of the state of the art techniques

The advancement in information communication technologies has seen the rise in the deployment of various information exchange devices in the healthcare sector. Among these technologies is the Tele-care Medical Information Systems (TMIS) in which remote users can establish a connection with the hospital medical server and share the necessary information between them. This can potentially offer doctors and patients more reasonable treatment plan, as well as helping address the huge medical expenses and excessive medical treatment duration. There is therefore need to store patient data in the end devices, as well as transmit this data over public channels to facilitate decision making. This paper sought to review the security schemes that have been developed over the recent past to protect the patient data stored or transmitted in TMIS.
