IV. PROPOSED FRAMEWORK

Here is a proposed framework for identifying counterfeit products using blockchain technology:

1. Product identification: Each product is assigned a unique identifier that is recorded on the blockchain. This identifier could be a QR code, a barcode, or an RFID tag.
2. Supply chain tracking: The movement of the product through the supply chain is recorded on the blockchain. This includes information such as the date of manufacture, the location of each step in the supply chain, and the identity of the parties involved in each step.
3. Authentication: Consumers can use a smartphone app or other device to scan the product identifier and verify its authenticity. The app would access the blockchain to retrieve the information recorded during the supply chain tracking phase and use this information to verify the product's authenticity.
4. Anti-counterfeiting measures: The system can include additional measures to prevent counterfeiting, such as tamper-evident packaging or specialized tags that are difficult to replicate.
5. Enforcement: In cases where counterfeit products are identified, the blockchain can be used to track the source of the counterfeit and help enforce legal action against those involved in the production and distribution of counterfeit products.

This framework would require collaboration between producers, distributors, and retailers to ensure that all relevant information is recorded on the blockchain. It would also require the development of consumer-facing apps or devices that can easily access the blockchain and authenticate products. Additionally, there would need to be legal mechanisms in place to enforce the identification and punishment of counterfeiters.

V. SYSTEM ARCHITECTURE

Here is a possible architecture for a blockchain-based system for identifying counterfeit products:

1. Front-end applications: These are the applications used by consumers to authenticate products. The applications could be mobile apps, web apps, or other devices that can scan the unique identifier on the product and access the blockchain to retrieve information about the product's origin, history, and authenticity.
2. Smart contract: A smart contract is a self-executing contract with the terms of the agreement between buyer and seller being directly written into lines of code. In this architecture, a smart contract could be used to ensure that all parties in the supply chain comply with the rules and regulations of the system. For example, the smart contract could specify the type of information that needs to be recorded on the blockchain at each step of the supply chain.
3. Blockchain network: The blockchain network is where all the information about the product is stored in an immutable and transparent ledger. The blockchain could be a public blockchain or a private blockchain, depending on the requirements of the system. The blockchain could be implemented using any of the available blockchain technologies such as Ethereum, Hyperledger Fabric, Corda, etc.
4. IoT sensors: The system could also include IoT sensors that could be used to track the product's movement through the supply chain. The sensors could track information such as temperature, humidity, and location, and record it on the blockchain.
5. Data analytics and reporting: The system could include data analytics and reporting tools that could be used to analyze the data recorded on the blockchain. This could include identifying patterns in the movement of products, identifying potential counterfeiting hotspots, and generating reports on the system's performance.

Overall, this architecture is designed to ensure that all relevant information about the product is recorded on the blockchain and is accessible to consumers, producers, and regulators. By using smart contracts and IoT sensors, the system could help ensure that all parties in the supply chain comply with the system's rules and regulations, and provide consumers with a high level of confidence in the authenticity of the products they purchase.

a. Manufacture: A block is added to the Ethereum blockchain using the manufacturer's Ethereum wallet after logging into the manufacturer account to create a QR code for the product and add any further information that is necessary. If both are present, a connection will be made between the wallet addresses of the entity and the user of our local database. If just the block is published to the digital ledger, the manufacturer will enter data from his own account and wallet.

b. Supplier: After entering into their account as a supplier, the product's QR code is scanned by the supplier. The manufacturer's entered product information is available to the seller. It injects extra information about the item—like the shop's location—into the Blockchain. These details are visible to the buyer.

c. Customer: Customers can scan a QR code that details the history of transactions and enables them to examine the integrity of a product to confirm its authenticity. The client will be aware that the goods are not genuine if the final location is different from the purchase location at the time of the customer's purchase following the QR scan in the supply chain history. After learning about counterfeiting, the purchaser comes to the conclusion that the QR code was stolen.

d. QR Code:  QR codes can be used as a unique identifier for products in a blockchain-based system for identifying counterfeit products. Here is how it could work:

1. Assign a unique QR code to each product: Each product is assigned a unique QR code that is printed on the product or its packaging.
2. Record the QR code on the blockchain: The QR code is recorded on the blockchain, along with other relevant information such as the date of manufacture, the location of each step in the supply chain, and the identity of the parties involved in each step.
3. Authenticate the product using the QR code: Consumers can use a smartphone app to scan the QR code and authenticate the product. The app would access the blockchain to retrieve the information recorded during the supply chain tracking phase and use this information to verify the product's authenticity.
4. Anti-counterfeiting measures: The system can include additional measures to prevent counterfeiting, such as tamper-evident packaging or specialized QR codes that are difficult to replicate.
5. Enforcement: In cases where counterfeit products are identified, the blockchain can be used to track the source of the counterfeit and help enforce legal action against those involved in the production and distribution of counterfeit products.

Using QR codes in a blockchain-based system for identifying counterfeit products can provide a quick and easy way for consumers to authenticate products. It also allows for the efficient recording and tracking of product information on the blockchain, which can be used to enforce anti-counterfeiting measures and identify the source of counterfeit products.

VI. SCM AND BLOCKCHAIN TECHNOLOGY

Supply chain management (SCM) and blockchain technology can work together in a system for identifying counterfeit products.[8] Here is how they could be integrated:

1. Record the supply chain on the blockchain: The movement of the product through the supply chain is recorded on the blockchain, including information such as the date of manufacture, the location of each step in the supply chain, and the identity of the parties involved in each step.
2. Ensure transparency and traceability: By recording the supply chain on the blockchain, the system can provide transparency and traceability, allowing all parties involved in the supply chain to access the same information.
3. Use smart contracts to enforce rules and regulations: Smart contracts can be used to ensure that all parties involved in the supply chain comply with the rules and regulations of the system. For example, the smart contract could specify the type of information that needs to be recorded on the blockchain at each step of the supply chain.
4. Authenticate products using blockchain technology: Consumers can use a smartphone app to scan a unique identifier on the product and access the blockchain to retrieve information about the product's origin, history, and authenticity.
5. Use data analytics to identify potential counterfeiting hotspots: The system can include data analytics tools that can analyze the data recorded on the blockchain to identify patterns in the movement of products and potential counterfeiting hotspots.

By combining SCM and blockchain technology, the system can provide a high level of transparency and traceability throughout the supply chain, making it easier to identify the source of counterfeit products.[9]The use of smart contracts can also help ensure that all parties in the supply chain comply with the rules and regulations of the system, and the use of data analytics can help identify potential counterfeiting hotspots, enabling proactive measures to be taken to prevent counterfeit products from entering the supply chain.

Conclusion

A blockchain-based system for identifying counterfeit products can provide a high level of transparency, traceability, and security throughout the supply chain. By recording information about the product\'s origin, history, and authenticity on an immutable and transparent ledger, consumers can easily authenticate products using a smartphone app, increasing their confidence in the products they purchase. The use of smart contracts and IoT sensors can also help ensure that all parties in the supply chain comply with the system\'s rules and regulations, preventing counterfeit products from entering the supply chain. In conclusion, the integration of blockchain technology in the fight against counterfeit products has the potential to revolutionize supply chain management and consumer protection. By providing a reliable, secure, and decentralized system for tracking and authenticating products, blockchain can help reduce the prevalence of counterfeit products and increase consumer trust. However, implementing such a system requires collaboration among various stakeholders, including producers, retailers, regulators, and consumers, to ensure the system\'s success. Further research and development are needed to address the technical, social, and economic challenges of implementing a blockchain-based system for identifying counterfeit products.
