Implementation of Big Data and Blockchain for Health Data Management in Patient Health Records

Abstract

Blockchain Technology (BT) and Big Data (BD)-based data management solutions can be used for storing and processing sensitive patient data efficiently in the healthcare field. While many institutions and industries have recognized the significance of both technologies, few have implemented and executed them in the health sector when it comes to the management of patients’ medical records. By leveraging Patients’ Health Records (PHR) data, the purpose of this paper is to develop a practical application with an architecture built on BT and BD technologies and to help organizations manage data requirements and enhance data security, provenance, traceability, availability, and effective identity management. For that purpose, a case study was developed, which covers the BT and BD key considerations, as well as key issues such as policies, smart contracts, consent, and provision of secure identities, so that records are properly managed and controlled. Hence, the purpose of this study is to summarize the key characteristics of a practical EHR implementation, emphasizing security measures and technologies to decipher the effectiveness of the included technological components, such as decentralized identification, consent management, and private BT management. According to the results of the case study research, the presented solution has high accuracy and is capable of managing PHR effectively. Additionally, it has been shown to have a high practical value when it comes to meeting the accuracy and real-time requirements of BT and BD applications.
