Blockchain-based Anti-Counterfeit Product Identification System

Aim:

       Our study aims at Blockchain-based Anti-Counterfeit Product Identification System using QR Code for tracking and verifying authenticity of products across various industries.

Abstract:

       Counterfeit products that are manufactured by a company’s current or former outsourcing supplier without the manufacturer’s permission or the customer’s knowledge. Goods that were produced by outsourcing suppliers but failed to meet the manufacturer’s quality standards and were not disposed of properly. One of the key challenges in addressing the problem of counterfeit products is identifying and taking action against those responsible as it may involve multiple components of a business’s supply chain model.Goods that are cheap, low-quality imitations of the actual product and lack traditional packaging that are sold through unconventional channels to consumers who are knowingly buying them. Genuine products that have been reverse-engineered using stolen or replicated designs and are sold to unaware consumers.

        Counterfeits are defined as illegally made products that imitate authentic items but usually have inferior quality in aspects such as functionality, dependability, and longevity.By creating an immutable record on the blockchain, it is possible to verify the authenticity of products and protect consumers from purchasing counterfeit goods. This could be implemented through the use of smart contracts which are self-executing contracts written in lines codes stored and executed in the blockchain. This technology also enables legal enforcement organizations to definitively prove that questionable products are counterfeit by tracing their provenance. So, in this paper we propose a Blockchain-based Anti-Counterfeit Product identification system using QR Code into the supply chain as a breakthrough solution to prevent counterfeiting by offering multiple distinctive features and benefits, such as transparency, traceability, security, and immutability.

Existing System:

       The existing anti-counterfeit system uses public blockchain to store the product details and for further usages. Also, they used local database to implement role-based access.

Disadvantages:

         The proposing system will store only the image Url in blockchain due to the limitation that storing images directly in blockchain is expensive.

 Proposing System:

          In the proposed system, we focused to prevent counterfeiting of Products using QR code.Product authentication and tracking within the supply chain can be achieved using technological solutions, which can be categorized as either overt or covert. Overt technologies are easily visible and facilitate straightforward product authentication but are vulnerable to replication by counterfeiters and they have limited durability. In contrast, covert technologies provide a higher level of security but require specialized reading devices for product authentication. These technologies are more difficult to replicate and have a longer lifespan but are typically more expensive.QR codes are considered an overt technology because they are easily visible and can be scanned by an app that can decrypt the encrypted product code.

      The app also communicates with a server hosted by the manufacturer that verifies the buyer’s identity and the product number. This way, the authenticity of the product can be ensured by using the QR code as a digital signature. The Product updation by Supplier and Retailer is done only after retrieving the product details by QR scanning. The consumer will get the authenticated product by verifying the Product History of the Product from Manufacturer to Supplier, then Supplier to Retailer. The whole history will be retrieved with the help of QR Scanning.If the Consumer decides to buy the product, they will make payment to retailer using Ethereum Wallets.

Advantages:

         The tracking and detection of counterfeited products using QR is cheaper and simple.Moreover, the system is fully decentralized and transparent, with all product information and transactions recorded on the blockchain and accessible to all parties.
