Blockchain-Enabled Security and Trust Models for the Internet of Medical Things (IoMT) in Modern Healthcare

Abstract

Sensors, wearables, implanted devices, and cloud platforms provide real-time monitoring, diagnosis, and clinical decision-making with the Internet of Medical Things (IoMT). Growth of IoMT infrastructure affects data privacy, cybersecurity, interoperability, and trust. IoMT systems, non-standard communication protocols, device capabilities, and medical network incursions are covered. We suggest data fusion, encryption, and decentralised trust enforcers for patient data. A decentralised, unchangeable, and secure blockchain. Blockchain-based solutions protect IoMT data flow, eliminate single-point-of-failure, and secure distributed medical device trust evaluation. Distributed ledger data integrity, authentication, and trust score storage improve active blockchain trust models. AI, data fusion, cloud/fog computing, smart hospitals, and blockchain secure IoMT. This chapter covers IoMT system design, cybersecurity, MULC frameworks, and blockchain-based health innovations. We discuss open research, regulation, and resilient, scalable, and dependable IoMT ecosystems.
