ABSTRACT

          End consumers face threats to their finances, health, and safety when counterfeit or duplicate goods are manufactured and marketed. Through revenue loss, product defamation, downtime, replacement costs, causing brands to spend money battling counterfeits, compromising partner trust, stealing sales, etc., it also has an adverse effect on the economic growth of original manufacturers and businesses. A block chain-based system that uses barcodes and QR codes to authenticate objects is suggested as a solution to this problem, enhancing security with the SHA-256 algorithm. This technology makes use of a camera scanner to confirm the product's unique code that is kept on an impenetrable block chain, guaranteeing the legitimacy of every item thanks to the cryptographic strength of SHA-256. The consumer is notified if a product's code matches the block chain record after it is scanned; if there are any differences, the manufacturer and the customer are notified about the product's counterfeit status. By giving consumers direct verification capabilities and protecting producers' interests with an opaque, safe, and secure verification system against counterfeit goods, this strategy drastically lowers reliance on merchant promises.

Keywords: Block chain, smart contracts, QR (Quick Response) code, anti- counterfeit.
