Abstract

In recent years, industries involved in manufacturing products have experienced an increasing reliance on counterfeit items. This phenomenon significantly impacts businesses' sales and profits. To address this challenge and ensure the authentication of genuine goods across the supply chain, a functional blockchain system is essential in preventing fraud and counterfeiting of goods. Blockchain technology allows customers to verify the product's origin without depending on trusted third parties for secure understanding of the product's authenticity. An application utilizing blockchain technology inherently ensures "tamper-resistant" data content. A blockchain serves as a decentralized and distributed digital ledger that stores transactional documents, known as public blocks, across numerous networks' databases. This study proposes the use of a barcode scanner to identify counterfeit goods, connecting each barcode to a Blockchain-Based Management (BCBM) system. The suggested technique involves recording product information and its unique code as database blocks within the blockchain. It begins by acquiring the customer's specific code and then cross-references it with the records in the blockchain database. If the code matches, the buyer receives confirmation; if not, the purchaser is prompted to provide the product's purchase location. This step aids in determining the source of any counterfeit items.
