Block chain-Enabled Visual Authentication for Unauthorized Product Detection

Abstract

Increase in globalization has made the supply chains worldwide grow exponentially and has also resulted in an increase in the risk of counterfeit and unauthorized products entering the market, thereby causing economic losses and a decrease in consumer trust. Traditional mechanisms for authentication of products involve using a lot of centralized databases, which are exposed to data tampering, data duplication, and single points of failure. To solve these problems, a blockchain-based visual authentication framework for detecting unauthorized products is proposed in this research paper. The proposed system combines blockchain and QR for visual verification, ensuring secure, transparent and tamper-proof product authentication throughout the life cycle of product. The products are each registered with their unique identifiers and cryptographic hash which are immutably implemented into a smart contract and stored on a private accelerated or simulated block chain. Linked to blockchain by QR codes, end-users can check product authentic through a scan and find the verification details in real time. The system has role-based interactions between administrators, managers, sellers and consumers that enable controlled processes for product registration, transferring of ownership, and verification processes. By taking advantage of cryptographic hashing, decentralized ledger principles, and visual authentication mechanisms, the resulting approach wilts more traceability, avoid the circulation of duplicate or fake products, and improve trust between stakeholders. This is work on system design, workflow and functional architecture.
