Integrated and Secure Medical Care Using Blockchain Technology

Abstract

In an era of swift technological progress in healthcare, there is an urgent need for solutions that elevate data security, enhance transparency, and streamline patient management. This study proposes an innovative healthcare system underpinned by blockchain technology to guarantee robust data integrity, protect patient privacy, and secure medical transactions. The architecture employs the Flask framework for web development, PostgreSQL for database handling, and the Ethereum blockchain with Web3 integration for maintaining decentralized records. Among its core features are fortified user authentication, tamper-proof prescription storage, a comprehensive hospital search tool, and one-time password (OTP) verification. Leveraging the decentralized nature of blockchain, the platform effectively thwarts unauthorized modifications and fraudulent practices, thereby cultivating a climate of trust between patients and healthcare providers. The paper further details the system’s design, the methodology for implementation, and suggests avenues for future enhancements.
