Securing Sensitive Patient Data in Healthcare Settings Using Blockchain Technology

Abstract

The utilization of electronic health record (EHR) has become common in the healthcare industry, enabling the storage and exchange of patients' medical information across different healthcare organizations. However, concerns regarding the security and privacy of patient data have arisen due to the centralized nature of conventional systems. To address these issues, a blockchain-based solution has been proposed to enhance data security and system efficiency. This chapter introduces a blockchain-based system designed to manage and secure patient data within a single record controlled by the patient. The Ethereum network was utilized to develop this decentralized system. The solution not only empowers users by granting them enhanced authority over their confidential information but also advocates for the incorporation of blockchain advancements within the healthcare domain. The proposed system offers improved data security and accessibility, addressing concerns related to the privacy and integrity of patient records in traditional EHR systems.
