A Systematic Review

Abstract

In modern era, the internet of things (IoT) has transfigured the medical industry, empowering the unified collection and exchange of patient data. However, this increased connectivity has raised significant concerns regarding the safety and confidentiality of electronic healthcare records (EHRs). This systematic review explores the security and privacy issues surrounding IoT-based EHRs and presents an in-depth analysis of how blockchain technology can be employed as an effective countermeasure to address these challenges. The chapter provides an overview of IoT in healthcare, highlights the vulnerabilities of EHR systems, and discusses the potential threats to patient data. It then delves into the principles of blockchain technology and its applicability to enhance EHR security and privacy. Various blockchain-based solutions and implementations are reviewed, and their advantages and limitations are discussed. This systematic review investigates the incorporation of IoT with EHRs in healthcare and contributes towards better understanding of the synergy between IoT, EHRs, and blockchain in the healthcare industry and assists as a valuable supplement for academics, practitioners, and policymakers. Additionally, the survey presents case studies and real-world examples of successful blockchain integration into healthcare systems. Finally, this chapter concludes by outlining the future prospects and challenges of utilizing blockchain technology for securing IoT-based EHRs and emphasizes the importance of a holistic approach to safeguarding patient data.
