IoT-Based Electronic Health Records (EHR) Management System Using Blockchain Technology

Abstract

Health care is the most important factor for the quality of life and IoT has provided us with the capabilities to improve the standards of health care. With the advancement in IoT, the capabilities to incorporate the mobility of patients has seen a great leap. With the prior knowledge of a patient's medical records, the doctor can make quick and efficient decisions. However, current electronic health record systems that are used to manage and store medical records of the patients suffer from issues including heavy bookkeeping, security, data integrity, and privacy. There is also no standard inter-connection to store and retrieve medical records of patients among the majority of the hospitals. In this book chapter, we present a permissioned blockchain-based system that could be used to store the patient records in a secure way i.e., the system will be patient-centric. Also in this system the patient's health can be monitored using IoT sensors and that data will be stored in the cloud and accessed using blockchain only. In this system, the patient will have control over the access to their medical records i.e., this system will be patient-centric which is not the case with current electronic health record systems. Hyperledger Fabric Blockchain was used to implement this project and to store medical records of patients and AWS storage has been used. To receive data from IoT sensors and send that to the cloud, mobile devices were used.
