Abstract—The assessment of Electronic Medical Certification (EMC) plays a pivotal role in modern healthcare infrastructures, serving as a comprehensive repository for patients' medical histories. Given the inherent challenges related to security and privacy within electronic medical certification systems, there exists a critical need to address the issues of system incompatibility that hinders data sharing among healthcare providers. This not only raises concerns over potential data breaches but also underscores the diminished control patients have over their own medical information. Blockchain technology, known for its significance in securing confidential corporate data, offers a promising solution to redefine the management of medical records. By leveraging a decentralized, peer-to-peer network, blockchain has the potential to transform the security dynamics and enhance the integrity of healthcare record exchanges. This research introduces a novel, lightweight blockchain framework, utilizing the Flask technology, aimed at securely storing and presenting patient statuses and detailed logs of disease diagnosis transactions. Within this envisioned blockchain architecture, patients are represented as unique assets, with their historical health data forming the individual blocks of the chain. The findings of this study suggest that by adopting blockchain technology, healthcare entities can surmount existing barriers, paving the way for a more effective and patient-focused electronic medical certification system. Such advancements promise to fortify the Electronic Health Record (EHR) systems, ensuring a secure, transparent, and efficient healthcare delivery model.
