Digital Locker using Block-Chain

Abstract

The Rapid digital transformation has created an urgent need for secure and reliable document management systems. Traditional digital storage methods are often vulnerable to tampering, unauthorized access, and single points of failure. This paper presents a Blockchain-based Digital Locker system designed to offer secure, decentralized, and tamper-evident storage for digital documents. Leveraging the inherent properties of blockchain immutability, transparency, and distributed consensus our system ensures the authenticity, integrity, and traceability of stored documents. The platform includes features such as role-based access control, cryptographic verification, and real-time audit trails. This Digital Locker not only empowers individuals with control over their personal documents but also facilitates secure document sharing and verification for institutions and service providers. The proposed system is a scalable, robust solution for digital document management in sectors such as education, healthcare, and governance.
