An Overview on Security and Privacy of Data in IoMT Devices: Performance Metrics, Merits, Demerits, and Challenges

Abstract

The Internet of Medical Things (IoMT) emerges with new trendsetter device applications, where it defines the incorporation of medical devices with the Internet of Things (IoT). The healthcare sector continues to encounter challenging obstacles that have an impact on the quality of treatment provided to patients. To get rid of this problem, IoMT is being deployed to achieve the high reliability and efficiency of the health system. The IoMT devices are superimposed with clinical information as they contain the details of patient health data, address, and other patient identifiers. By containing such amount of sensitive information, it becomes cumbersome to preserve data privacy and security. Due to inadequate security and privacy precautions, patient health data is susceptible to leakage, which has a direct impact on the patient’s life. In addition, the majority of medical devices are susceptible to cyberattacks, putting patient information at risk. Inadequate control of life-support equipment can have a devastating effect on patient outcomes. Thus, this survey intends to review the various security models of IoMT devices using standard techniques to support health care systems. It provides a wide range of literature reviews regarding IoMT systems and compares them with traditional methodologies. This review work exhibits the motivation for current technologies to maintain the security and privacy of patients’ data with IoMT devices. The systematic review entails background on security in IoMT devices, techniques for security, usage of diverse validation measures, and also discusses the problems and motivation for future research work.

Patient-Generated Health Data (PGHD): Understanding, Requirements, Challenges, and Existing Techniques for Data Security and Privacy

“…This article is a completely revised and strongly extended version of our contribution to the pHealth 2022 Conference in Oslo [ 1 ]. In the predigital era, patient health data was mostly gathered during face-to-face consultation and manually recorded on paper.…”

A blockchain-based computerized network infrastructure for the transparent, immutable calculation and dissemination of quantitative, measurable parameters of academic and medical research publications

“…They have blockchains’ immutability, cybersecurity, and interoperability characteristics as those which would facilitate adequate data privacy, storage, and management at minimal cost and risk. Khatiwada and Yang 3 describe IoMT (Internet of medical things) as promising but potentially susceptible to leakage of patient data and having inadequate security and privacy precautions. Blockchain technology would further transform the realm of IoMT, eliminating most of the above-mentioned concerns.…”

“…One study found that in the United States, an average patient sees 18.7 different physicians and has 19 medical records during their lifetime. 3 In terms of data privacy, a method to encrypt patient data before sending it to the blockchain was already proposed. 8 …”
