A Blockchain-Based System for Secure and Transparent Healthcare Insurance Claim Authentication

Abstract: The healthcare and insurance industries face significant challenges in data authenticity, fraud prevention, and secure processing. This paper presents a blockchain-based insurance claim authentication system that ensures transparency, security, and efficiency. The system facilitates seamless interactions among hospitals, insurance companies, and patients using Ganache, Truffle, MetaMask, and Django. It leverages cryptographic methods, digital signatures, and smart contracts to validate transactions, thereby enhancing trust and minimizing manual errors.
