Fake Product Identification by QR Code Using Blockchain

Abstract

Ever since its inception in 2008, Blockchain technology has been widely used in most industries to ensure data security and authenticity. From Bitcoin to Blockchain-as-a-Service (BaaS), it has been increasingly adopted. Counterfeiting is one of the biggest issues that companies are fighting, impacting revenues, brand value, and customer trust. In this review, a decentralized Blockchain- based supply chain solution to ensure product authenticity without third-party dependency is discussed. Through the use of distributed ledger technology, authentic and fake products can be identified at all levels. Unique QR codes, produced by the system proposed here with SHA-256, provide transparency and traceability to each product. Blockchain-based anticounterfeiting mechanism provides a secure, tamper-evident method of proving product authenticity, allowing organizations to uphold integrity in their supply chain.
