Using Blockchain Keys to Enhance The Security of Medical Records: Role of Medivault

Abstract
MediVault introduces a new health data system designed to ensure the security, privacy of patient records while giving access to only authorized members. While responding to the challenges faced by traditional systems, blockchain technology empowers individuals and other stakeholders in this system. The system has multiple portals, including hospital, patient, physician and pharmacy, to enable seamless transactions among consumers involved. Through a decentralized system data access is controlled based on individual consent processes in smart contracts. Doctors can safely update prescriptions, ensuring consistent and transparent records of patients. MediVault not only provides data security and transparency but also improves healthcare performance by providing accurate and accessible information to healthcare providers. This research marks a major breakthrough in healthcare data management, delivering robust solutions that prioritize patient ownership and security while transforming the landscape of the health records system.
