Spotting Fakes - How Technology Fights Counterfeit Goods
$500 Billion in Annual Counterfeiting
OECD and EUIPO estimate global trade in counterfeit and pirated goods at about $500 billion as of 2016, up to 3.3% of world trade; the same framework put the 2019 figure at about $460 billion, so the order of magnitude has not moved. Beyond luxury goods, counterfeit medicines, auto parts, and electronics pose life-threatening risks. WHO estimates 10% of medicines in developing countries are substandard or falsified.
Unique Patterns as Certificates of Authenticity
Each product receives a globally unique pattern at the factory. Consumer scanning queries the manufacturer's server for authentication. What defeats a copied pattern is not print quality but the server-side record of when and where each code was used. Genuine items are marked as released at shipping or sale, and repeated queries for one code from distant regions within a short window raise a duplication alert for the manufacturer to trace back through the distribution path. A buyer rescanning their own item is never flagged, because the judgement compares the spread of query locations and times against shipping records rather than counting scans.
Blockchain Combination
Recording manufacturing date, factory, distribution route on blockchain creates tamper-proof provenance. Wine bottles already offer full history via pattern scan. Consumers verify authenticity before purchase.
DNA Markers and Invisible Ink
Synthetic DNA ink prints patterns whose sequence cannot be read from the outside, so reproducing a match is not practical. Invisible IR/UV ink helps too, but UV lamps are cheap, so hiding the existence of the pattern cannot be the defence. Ink composition, the wavelength returned under light, and the strength and decay of the response are designed per product, and the inspection device checks that the response matches that design. Look-alike fluorescent ink fails the check, and a counterfeiter needs both a supply route for the special ink and dedicated printing equipment.
Why a pattern can be used to prove authenticity
The reason a black-and-white pattern helps prove authenticity is that a unique code can be assigned to each individual product and tied to the manufacturer's record. When a user scans the code, that information is matched against the legitimate record, and whether it is genuine is confirmed. Furthermore, there is a mechanism that detects, as unnatural, when the same code is scanned many times in separate places. Not just attaching a pattern, but having a mechanism that checks against a trustworthy record, is precisely what makes the code function as a clue to distinguish genuine from fake.
Technology alone cannot fully prevent it
No matter how clever the mechanism, it cannot completely prevent counterfeiting on its own. The counterfeiting side sometimes copies the pattern itself to look just alike. That is precisely why, in addition to confirmation by code, combining multiple technologies and having consumers themselves hold a habit of checking become important. Even with a hard-won confirmation mechanism, it means nothing if no one scans. The power to distinguish the genuine is demonstrated only when both technology and the awareness of the people who use it come together. Not fully trusting the mechanism, but an attitude of confirming with your own eyes, becomes the last defense.
What Consumers Can Do
Scan and verify before purchasing expensive items. 'Product not registered' results suggest counterfeits. Extremely low prices are a red flag. Legitimate products have legitimate prices for a reason.
