BrandWatch Develops Four - Level Authentication

Brandwatch Technologies has introduced a new variety of its up-converting taggant technology that combines four levels of covert protection.  This, it says, is the only one marker that provides multiple simultaneous identification and offers users a unique fingerprint that can be embedded into products or documents.

BrandWatch, which was taken into new ownership in 2007, produces microtaggants based on inorganic up-converting anti-Stokes phosphors, together with proprietary handheld readers.

One of the first developments under the new ownership was SpectraTagg. This range of taggants has now been tuned to offer a combined UV and IR response with two other covert markers, yielding four distinct layers of protection which can be read simultaneously by the company’s Reveal detectors.

In addition to SpectraTagg, the company also offers MicroTagg, an up-converting phosphor material with dual factor authentication that is readily incorporated into polymeric and other matrices.  When irradiated with energy of a specific wavelength, the MicroTagg particles absorb the energy and re-emit it at a different wavelength, which is detected by the company’s readers.

The company’s technology originated in military research and has received several certifications as to its stability, longevity and durability. The taggants share a set of common properties, being inorganic, inert and non-toxic, insensitive to sunlight and stable at temperatures up to 1000° C.  They can be easily incorporated into inks, dyes, polymers, textiles and pulp, will not alter the host’s chemical make-up, have an extremely long shelf-life and are capable of being detected at low concentrations.

Cash Applications
The industries targeted by BrandWatch include currency – not only as a machine-detectable and forensic authentication feature for banknotes but also in cash degradation systems as part of the inks that enable stolen notes to be identified and traced. The company has already secured a new customer in this sector – an un-named cash handling company. According to Steve Delepine, BrandWatch’s newly-appointed VP for Business Development, the company’s solution is particularly suited because, while the supposedly indelible inks can be washed off the notes to a degree that enables them to be recirculated after ten or so washes, its taggants adhere to the paper fibres as well, staying on the notes long after the ink has gone.
