Fraudulent products can enter the supply chain at various stages. A fraudulent product may look genuine when it reaches a retail store or consumer. Traditional methods of verifying authenticity often rely on labels. Other aspects they consider are packaging, serial numbers, or documentation. These methods remain valid. But they say little about the product's history.
Blockchain technology provides an alternative solution. Blockchain can create a unified electronic ledger for product movement. It does so from manufacturing to distribution and sale. Integrating anti-counterfeiting technology with blockchain enhances authenticity verification.
However, it is not a magic wand to prevent fraudulent products. Its strength lies in creating trusted records that detect abnormal activities.
Understanding Blockchain in Product Authentication
A blockchain is a digital ledger that stores records across a network. Once the information is recorded, changing records in the ledger becomes difficult.
The system supports product authentication. It does so by creating records linked to specific products or batches. These records may include manufacturing, transaction, and verification details.
It provides product authentication technology with a consistent history, allowing an authorized party to access that history. The verifier does not have to verify the information on its own, but instead can check the product's details.
The system also helps in genuine product verification once the record and the product match.
Creating a Digital Identity for Each Product
A system should link a physical good to its digital version. A business can use serial numbers and secure identifiers. It also relies on QR codes, NFC tags, and other technologies.
A product can have a unique product identifier during manufacture. The product identifier links the physical product with its digital version.
The system captures the event whenever an authorized entity interacts with the product. This way, one can have a comprehensive history of the product. It is available from manufacture to distribution.
This approach enables product-level authentication. It authenticates the product itself, not the brand or product type. Instead, it authenticates the product itself.
How Blockchain Supports Verification
Imagine a customer buying a high-value product. The customer scans its identifier using a mobile device. The verification platform checks the identifier against the associated record.
The system can provide a verification result if the identifier exists and the information matches the expected details. The system can flag the product if the identifier does not exist. The same may happen when it appears duplicated or shows an unusual history.
This approach can support product verification without depending entirely on visual inspection.
However, the blockchain itself does not determine whether the physical product is genuine. It records information supplied to the system. The original data must therefore come from trusted sources.
Think about a scenario where a buyer has purchased a valuable product. The buyer then scans the product ID using their mobile phone. The verification software will compare this ID with the records for that ID.
The verification is successful if the ID exists and matches the expected data. The product can be flagged if the ID does not exist or the ID's history looks suspicious.
The above-mentioned system can support product verification but does not rely on visual inspection.
However, blockchain technology does not determine whether the product is truly authentic. Blockchain technology stores the information submitted to the system. Therefore, it should be correct.
The Importance of Trusted Data
Blockchain technology cannot correct inaccuracies at their root. Once inaccurate information is entered, the blockchain will ensure that inaccurate information is stored.
This is one of the most crucial drawbacks of using blockchain for authentication.
A company needs proper systems in place to create and manage records. It must have proper authentication data coming from manufacturing systems, approved distributors, authentication devices, and other credible sources.
Physical security mechanisms will help enhance the link between the object and its record. A credible identifier or mark on the object can prevent counterfeiters from stealing a legitimate product's identity.
This links physical and digital security.
Blockchain and Product Traceability
Detecting counterfeits is easier when a company knows its product's path. Blockchain can enable counterfeit detection through product traceability along the chain.
An original manufacturer may log the manufacturing process. A distributor may log the receipt process. A logistics firm may log the movement process. A retailer may log the delivery process.
All this data may increase supply chain visibility. Only authorized persons can determine whether the products have taken the correct path.
For instance, an unauthorized market where the products suddenly show up may raise suspicion. Having multiple products with the same identifier may indicate misuse.
None of this data conclusively shows that counterfeits are there. All this is data for investigating the matter further.
Combining Blockchain with QR Codes
QR codes provide an easy means of tying a physical product to its digital record. A consumer can use a smartphone to scan a code and get the service for verification.
But conventional QR codes are easily replicable. A fake product will have a duplicate code from the authentic product.
Companies can address this with secure QR code technology and additional authentication measures. The system does not just check whether there is a code. The system considers factors such as scan history, product information, location, and timing, among others.
This can make codes hard to replicate.
The aim is not to use a QR code alone as evidence of authenticity. The QR code should be part of the bigger authentication system.
Blockchain and NFC Authentication
An NFC system represents another approach for linking the physical asset with its digital twin. The NFC module installed in the product can communicate with a compatible smartphone or other reading device.
NFC authentication can offer a convenient verification experience for users. The system can obtain the necessary product information and link it to the corresponding blockchain-based record.
This approach can be particularly useful when packaging or labels may change. The physical component can serve as additional proof.
Protecting Supply Chains
False threats are not just a concern for the end consumer. False components can enter manufacturing. Diverted goods can reach the wrong sellers. Fake products can enter the distribution channels.
Blockchain-based systems can support supply chain security by documenting relevant transactions and movements.
Track-and-trace systems are another option for companies that want to monitor product movement. Combined with blockchain documentation, such systems could improve the tracking of product movement and handling of products by relevant parties.
Conclusion
Blockchain technology offers companies an opportunity to create well-structured digital documentation. Blockchain technology can enhance authentication. It can improve traceability. Also, it may increase visibility in the supply chain.
However, the technology's success in achieving its objectives depends on the quality of the data. Also, what matters is how companies link digital documents to physical products.
The most effective way to use the technology is to combine it with identification technologies and physical security. Also, it's important to consider reliable verification mechanisms and strong supply chain practices.
