Abstract
Healthcare industry operation needs resources and information sharing between business partners. Internet of things (IoT) aims to simplify distributing data collection in the healthcare business, sharing and processing information across collaborative business partners using appropriate information system architecture. However, a large portion of existing IoT-based healthcare systems leveraged for managing data is centralized, posing potential risks of a single point of failure in natural disasters. The medical data privacy and security problems could result from a delay in treatment progress, even endangering the patient's life. This chapter describes the use of blockchain-enabled secure management of healthcare systems. Blockchain technology contributes to transactional data's intelligent and flexible handling through appropriate convergence with IoT technology in supporting data integration, processing, and providing data privacy and security-related issues. Finally, the chapter presents challenges and solutions on blockchain-based electronic healthcare record (EHR) systems.
