Blockchain-Based Document Verification and Authentication System Using AI

Abstract: In moment’s digital period, the verification of documents similar as instruments, identity attestations, and contracts is a major challenge due to phony, manipulation, and lack of translucency. The proposed Blockchain- Grounded Document Verification and Authentication System ensure secure storehouse, inflexible record keeping, and tamper- evidence confirmation of digital documents. The system leverages blockchain technology combined with cryptographic mincing (SHA- 256) and smart contracts to produce a decentralized verification process. Each uploaded document is converted to a unique hash and stored on the blockchain, icing authenticity and traceability. The system is designed for educational institutions, government agencies, and private associations to corroborate instruments and legal documents without interposers.

Keywords: Blockchain, Smart Contract, IPFS, SHA-256, Ethereum, Document Verification, Decentralization.
