FAKE PRODUCT IDENTIFICATION USING BLOCKCHAIN

Abstract

In recent years, block chain has received increasing attention and numerous applications
have emerged from this technology. In our Project uses the decentralized Block chain technology
approach to ensure that consumers do not fully rely on the merchants to determine if products are
genuine. We describe a decentralized Block chain system with products anti-counterfeiting, in that way
manufacturers can use this system to provide genuine products without having to manage directoperated
stores, which can significantly reduce the cost of product quality assurance The manufacturing
as well as marketing of counterfeit or duplicate products and goods leads to consequential financial,
health and safety threat to end users. It also has adverse effect on the economic growth of original
manufacturers and businesses through revenue loss, product defamation, downtime, replacement
expenses, forcing many brands to spend money on fighting counterfeits, trust among business partners
can also be at risk, stealing sales etc. To overcome and stop these crucial effects of counterfeiting, a
blockchain based system is used in identification of original products and also detects duplicate products
to ensure the identification of original goods. In this project, with massive emerging trends in wireless
technology, QR (Quick Response) codes and barcodes provides a technique to cut down the practice of
counterfeiting the products. The fake products are identified using camera scanner, where QR or
barcode of the product or goods is linked to a blockchain to store product details and guaranteed unique
code of each product stored as blocks in the database. If the code in product matches, the notification
will be sent to the customer indicating the authenticity of the product and else if it does not match the
code in database, a notification will be sent to customer indicating that product is fake or counterfeited
and notification is also sent to manufacturer about the place of purchase if customer accepts the request
made by the application. This approach to cut down counterfeit ensures that consumers won’t
completely rely on merchants to determine if products are original or forged.
