Authentication of Digital Document using Blockchain

Abstract

In today's technology-driven landscape, the ease of access to information has led to a pressing concern: the proliferation of counterfeit documents. Document authentication plays a pivotal role in our daily lives, where proving our identity is crucial. Various identification documents like Aadhar cards, PAN cards, driving licenses, and passports require validation by human operators. To counteract the challenge of counterfeit documents, a highly accurate automated system has been devised. This system employs gradient optimization and domain-specific factors for matching ID documents with live face images. Addressing the scarcity of samples in numerous classes, a pair of interconnected systems with shared parameters facilitates efficient classifier strength training. The decentralized framework utilizes Ethereum blockchain-based innovation, ensuring digital document security through online storage, hashing, face verification, a peer-to-peer infrastructure, and QR code confirmation.
