ABSTRACT
Increased digital security and privacy is needed in today’s healthcare systems to protect doctor and patient details, information concerning medical equipment, drugs and their manufacturers, and medical insurance. A large volume of fragmented data, both clinical and non-clinical, can be accessed for various medical purposes. Ethical data sharing can be achieved using blockchain technology, which allows access to the data without third-party interference. Longitudinal views of transactions, interactions and data interventions should be verified and shared using blockchain technology in a more secure and systemic manner. Combining blockchain technology with the internet of things (IoT) can resolve many issues in the healthcare field, such as mis-identification of patients, drug supply-chain management, and continuous monitoring of patients in intensive care. This chapter considers the security aspects of blockchain technology in the healthcare IoT using fog computing and cloud computing. We focus on three major areas: electronic health records (EHRs), supply-chain management, and genomic data exchange. Using blockchain technology in the supply-chain management of drugs and drug delivery systems increases the visibility, traceability, and privacy of medicines and drugs.
