Product Authentication using Blockchain

Our objective is to employ a decentralized blockchain-based solution to ensure that consumers do not just rely on merchants to evaluate whether things are original or not. Customers should be able to figure out whether the product is original or not using our software proposed. The method for identifying fake products using blockchain technology involves the use of unique product identifiers for the products registered on the blockchain network. These identifiers are encoded as QR tags which are assigned to each legitimate product during the manufacturing process. Smart contracts are built by using solidity. When a consumer purchases a product, they could scan the identifier using a smartphone or RFID reader to access information about the product’s authenticity and supply chain history on the blockchain. This would allow consumers to easily verify that a product is legitimate and has not been tampered with, while also providing manufacturers with a tamper-proof record of their product’s supply chain. Additionally, the use of blockchain technology would enable real-time tracking of products, making it easier to identify and remove counterfeit products from circulation. We have proposed a novel blockchain-based product ownership management system (POMS) for the post-supply chain, which makes the efforts of counterfeiters to clone genuine tags redundant since they cannot prove the possession of products on this system. Thus blockchain, helped us to overcome problems in the supply chain like unauthorized products.
