Blockchain in Healthcare: Securing Patient Data and Transactions

Abstract

The healthcare industry is plagued by data inconsistencies, with patients and organizations dissatisfied by redundant contact information and impediments to acquiring real-time patient information. Blockchain technology, which has proven effective in boosting transaction security in the banking industry, is being examined as a solution. This study provides an approach for leveraging blockchain to share data among healthcare organizations. The study intends to improve the security and privacy of electronic healthcare records (EHRs) by employing blockchain technology, as existing centralized systems frequently reveal critical health data, lowering vulnerabilities and avoiding cyberattacks. Internet of Things (IoT) and blockchain have emerged into feasible digital technologies in the healthcare sector. Real-time data may be captured and saved utilizing IoT devices and blockchain, assuring transparency and security. This technique tackles billing and insurance claim challenges by assuring quick reporting, protected data storage, and a transparent system, therefore improving the overall efficiency and transparency of the healthcare industry. This study examines the benefits of Blockchain technology in healthcare, focusing on its capabilities, enablers, and unified workflow procedure. It highlights important Blockchain applications including detecting clinical trial deception, increasing data efficiency, minimizing data tampering, and offering security through unique storage patterns. Blockchain also provides flexibility, interconnectedness, accountability, and authentication for data access, assuring the security and confidentiality of health records.
