FAKE PRODUCT DETECTION USING BLOCKCHAIN TECHNOLOGY

Counterfeit products have become a major concern in industries like electronics, pharmaceuticals, and consumer goods, creating a strong need for reliable and tamper-proof verification systems. This paper introduces a blockchain-based approach to address this problem by ensuring transparency, immutability, and secure tracking of product information across all stages of the supply chain. In the proposed system, each product is assigned a unique hash that is stored on the blockchain and later converted into a QR code. As the product moves from manufacturer to end consumer, every transaction is recorded, forming a trustworthy and auditable trail. Customers can simply scan the QR code to confirm whether a product is genuine. This method lowers the chances of fraud, builds trust, and improves overall transparency. The results show that blockchain significantly strengthens product traceability compared with traditional, centralized systems.
