Security of Medical Internet of Things (MIoT)- A Bibliometric Analysis

Abstract

The integration of the Internet and communication technologies has improved our lives in numerous ways. To date, the Internet of Things has evolved the healthcare industry from healthcare 1.0 to 4.0 which is known as the MIoT. In Healthcare 4.0, data is shared among multiple stakeholders through the use of cloud computing, fog computing, and telehealth. MIoT devices and technology's interconnected, heterogeneous nature raises new concerns about access to confidential patient data, which is often done without patients' or medical staff's knowledge. This is because security and privacy concerns for MIoT devices and technology are frequently ignored or undermined by relevant stakeholders. Medical IoT security and privacy are becoming increasingly important as a result of the increasing number of security breaches targeting the MIoT in healthcare.To impartially reveal the research scenario of Security of MIoT biblioshiny and VOS viewer software are used to conduct a quantitative assessment of research papers belonging to this field for the period 2012–2021 in the Web of Science (WoS) and Scopus databases. From the results, it is seen that for the past 10 years, the sum of articles on Security of MIoT has increased. This research domain covers 35 territories. MIoT, Security, Privacy, authentication, access control are the most often used keywords in this field of research in recent years. The research flashpoints in the field primarily emphasize research directions such as the, the security and privacy concerns related to MIoT sensor data and how to get rid of them. The top five nations considering research volume are the China, India, Saudi Arabia, USA, and Korea, but a lack of collaborative work amongst these countries is seen. Finally, the paper provides future research directions on security of MIoT, such as Privacy of patient information, Lightweight Protocols for MIoT Devices, Trust management, patient data sharing and insecure networks.
