Nanoscale anti-counterfeiting tech reveals hidden image when breathed upon

By - August 7, 2014 6 Pictures
Allowing consumers to identify counterfeit goods is a tricky and expensive problem, as many security measures such as holograms might be easily mimicked by counterfeiters. A new nanoscale printing technique, however, allows researchers to create labels that reveal a "watermarked" image when breathed upon by the consumer. The labels are scalable and durable, and can be applied to many surfaces, yet are beyond the hands of those who might try to mimic them to fool consumers. Read More

Added DNA could be used to authenticate premium olive oil

By - April 25, 2014 1 Picture
When most people think of counterfeit goods, they probably picture things like handbags or watches. In fact, there's also a huge market for knock-off high-end food products, such as extra-virgin olive oil. Scientists from Switzerland's ETH Zurich research group, however, have come up with a possible method of thwarting the makers of that bogus oil – just add synthetic DNA particles to the real thing. And yes, consumers would proceed to swallow those particles. Read More

Silver nanowire "fingerprints" may be used to fight counterfeiting

By - March 24, 2014 1 Picture
The counterfeiting of high-end products is a growing problem, and has led to the development of countermeasures such as invisible woven patterns, butterfly wing-inspired printing techniques, and even synthetic DNA. One of the drawbacks of some of these approaches, however, is the fact that implementing them can be quite a complex process. Now, a team from the Korea Advanced Institute of Science and Technology (KAIST) has come up with something simpler – tiny jumbles of nanowires that form item-specific "fingerprints." Read More

Is that a real Gucci? Just check its DNA

By - September 25, 2013 1 Picture
Earlier this year, we heard about a gun and a fogging system, both of which tag criminals with synthesized DNA. The idea is that when those people are apprehended later, they can be linked to the crime by analyzing the location- or event-specific DNA still on their skin or clothing. Now, scientists at the Technology Transfer Unit of Portugal's University of Aveiro are developing something similar – DNA "barcodes" that can be applied to products, then subsequently read as a means of identification.

Laser device designed for Mars unmasks counterfeit honey

By - February 13, 2013 1 Picture
When someone mentions counterfeiting, it brings up images of money, watches or DVDs. It certainly doesn't make honey spring to mind, yet honey smuggling and counterfeiting is an international problem involving hundreds of millions of dollars. In an effort to combat this, the European Space Agency (ESA) is funding a demonstration project to adopt lasers designed to study the Martian atmosphere, to detect fake honey. Read More
