Blockchain based Application for Fake Product Detection

Abstract

This paper aims to study and introduce an innovative solution that combines cryptography and an immutable blockchain system to address the pressing issue of counterfeit products. The application's primary objective is to identify fake products within supply chains by ensuring data integrity, traceability, and transparency throughout the product's journey. By employing advanced cryptographic techniques, the application secures sensitive information and verifies product authenticity while preserving confidential details. Integrating an immutable blockchain ensures an unchangeable and decentralized record, making it exceedingly difficult for malicious entities to manipulate product records. Blockchain technology can verify the validity of a product and provide confidence to consumers regarding its legitimacy, effectively detecting counterfeits. The QR (Quick Response) code or an encrypted unique code, which is a very effective method for determining the uniqueness of the product, will be used by the model in the suggested system. The blockchain that is accessible after scanning the QR code provides data on the product, the maker, and the owner to assist customers in makinginformed decisions. This study provides a technique foridentifying fake products that uses blockchain technology. Keywords — Blockchain, Ethereum, Counterfeit Product, QR code, Solidity, Dapp.
