Brilliant counterfeit protection
Date:6/14/2010

For quite some time now, product piracy has been affecting more than just consumer goods, like watches and designer clothing. The producer industry also has to combat bogus and qualitatively inferior materials. Specialized security features, like watermarks, bar codes, RFID tags and holograms label the products, and thus safeguard them from falsification, theft and manipulation. So when it comes to security features: the more complicated it is to imitate a brand, the more secure the system. A team of researchers from four Fraunhofer Institutes recently engineered a brand new process that is particularly forgery-proof: We add various fluorescing dyes to the entire material, explains Dr. Andreas Hollnder of the Fraunhofer Institute for Applied Polymer Research IAP. With the aid of the fluorescence, we can precisely ascertain specific characteristics, and thereby recognize if we are dealing with the original, and if the quality standards have been met.

Fluorescence can be found in certain organic dyes: Irradiate them within a certain wave length range, and they emit their own light with a greater wavelength. The type of luminosity i.e., wavelength and light intensity depends on the physical and chemical properties of the materials to which the dye was applied. Various dyes react to different properties, such as pH value or viscosity. For example, a certain dye glows in a tightly-interlaced resin more strongly than in one that is not as dense.

To make a product counterfeit-proof, the researchers therefore add multiple dyes to the material. In this manner, an individualized marker emerges that is exceedingly difficult to imitate, says Hollnder. Thanks to the slight dosing, it is virtually impossible to decode the type and quantity of the dye additives: just a few ppb (parts per billion) of dye concentrates suffice to mark the material. Another advantage: The counterfeit protection definitely cannot be removed. Using conventional security features, the spot with the labeling can be eliminated from the material, theoretically speaking. But that approach doesn't work with our technology, since the dye permeates the entire material, and itself is a component of the identification label, says Hollnder. Beside counterfeit protection, the process is also suitable for an effective quality assurance, such as with coatings: With the aid of various dyes, manufacturers can monitor the chemical composition, degree of dryness and the thickness of the coat during the production process.

The new technology has already passed the first practice tests: Researchers marked barrier sheets for organic light-emitting diodes (OLEDs) and photovoltaics with dyes a development from the Fraunhofer Polymer Surfaces Alliance POLO. The process is basically ready to be used however, it still must be adapted to each material. A standard solution would also be contrary to the intention of the inventor: One reason for the high degree of security of our technology is precisely because there are only material-specific solutions, reiterates Hollnder.
