Blockchain-Enhanced DigiLocker for Secure and Duplicate-Free Document Management explores the application of blockchain technology to improve the security, integrity, and reliability of digital document storage systems. Traditional centralized platforms such as DigiLocker provide convenience and accessibility but remain vulnerable to document forgery, duplication, unauthorized access, and data breaches. This paper reviews existing blockchain-based document verification approaches and proposes an enhanced DigiLocker framework integrating cryptographic hashing, smart contracts, decentralized storage, and duplicate detection techniques. The proposed system ensures tamper-proof document verification, transparency, and user-controlled access while reducing manual verification efforts. The survey highlights advantages, implementation challenges, and future research directions for blockchain-enabled digital governance systems.
