BLOCKCHAIN BASED IDENTITY VERIFICATION SYSTEM

Traditional identity verification systems often rely on centralized databases, which are vulnerable to data breaches, identity theft, and unauthorized access. Blockchain technology offers a decentralized and secure solution for managing digital identities. This paper presents a blockchain-based identity verification system that ensures data integrity, transparency, and user control over personal information. By leveraging smart contracts and cryptographic techniques, the system enables real-time verification while minimizing the risk of data tampering. The proposed model enhances privacy, reduces dependency on centralized authorities, and increases trust between users and service providers. This approach is particularly relevant for applications in finance, healthcare, and government services.
