Secure Document Storage System using Web3

A document management system employing the Inter PlanetaryFile System (IPFS) and block-chain facilitates trusted sharing of sensitive data via user-defined access controls without intermediaries. One-time cryp- tographic gateway tokens enable recipients to access uploaded content from distributed storage. Evaluations validate selective retrieval in allowing con-fidential dissemination to permitted parties only. The system signifies how Web3 protocols inherently offer tamper-proof, decentralized sharing with strict need-to-know controls across security domains.
