Leveraging Blockchain for Secure and Transparent Patient Case Data Management: Insights from System Implementation and Use Cases

Abstract

The safe handling of patient information is essential in the healthcare industry, particularly as the quantity and sensitivity of health records increase. Present systems frequently depend on centralized databases that are susceptible to unauthorized access and data manipulation, thereby restricting transparency and security. Furthermore, these systems lack the traceability required for efficient patient data management, making them prone to errors and inefficiencies in data processing. This paper proposes a patient data ledger built on blockchain technology, incorporating decentralized data management and secure transactions via Ethereum to enhance patient data handling. By leveraging blockchain, we achieve immutable records and ensure transparent, secure, and tamperresistant data storage. Unlike conventional systems that depend heavily on intermediaries for trust, our blockchain-based ledger minimizes human intervention and employs smart contracts to automate data security and access. Utilizing Ethereum's blockchain along with Web3 and MetaMask, the system enables secure, user-friendly access and effective data logging. This approach provides a reliable and scalable solution, ensuring real-time transparency and efficient handling of patient information while significantly enhancing security.
