Identification of Counterfeit Products Using Blockchain in E-Commerce

Numerous applications have been developed using Blockchain in recent years as its popularity has grown. Any application that uses Blockchain technology as part of its architectural model guarantees the integrity of its data. Using a decentralized Blockchain system to verify drugs, companies, and brands can prevent counterfeiting while reducing costs at the same time. This paper presents a secure Blockchain-based model to counterfeit fake products in the market. A key is generated for each product, which is stored in the Blockchain. This key will also be fed into a QR code which will be attached to each product. This model uses a QR code-based approach to verify the truthfulness of the product by searching the Blockchain. As the Blockchain is immutable in nature, the data cannot be breached or modified. Also designed is an accompanying web-based application to implement this approach and discusses the software implementation process where the application scans the product code and confirms whether the given product is fake or not.
