Advances on networked ehealth information access and sharing: Status, challenges and prospects

Abstract

Internet of Medical Things (IoMT) is no longer a futuristic technology and has become a day-to-day reality with the increasing ease of availing modern internet services. IoMT services interconnect numerous healthcare ecosystem stakeholders, such as doctors, patients, pharmacists, etc., seamlessly under the light of Advanced Internet Communication Tools (AICT). Wireless Body Area Network (WBAN) is a primary constituent of any IoMT device, offering a data acquisition environment through various bio-sensors deployed in edge devices. The data generated through such edge devices should be stored securely in Electronic Health Server (EHS) for further analysis and knowledge inference by medical professionals. Thus designing access control techniques that prevent unauthorised access at the cloud and device level is crucial. Interoperability concern in the IoMT development cycle is becoming a focus of interest for many researchers because most devices and underlying protocols are highly heterogeneous. Lack of worldwide acceptable protocol standards is another major issue in dealing with platform interoperability. In this study, the authors describe the various existing device and data access control strategies such as RBAC (Role Based Access Controlling), CaPBAC (Capability-Based Access Controlling), and ABAC (Attribute-Based Access Controlling), etc. This article majorly surveys the literature from 2000 to 2020 on various access controlling and Interoperability aspects as they are potential players of modern IoT applications. The study also comprehensively discusses the state-of-the-art strategies that provide platform interoperability followed by crucial implementation challenges.
