BrandWatch Develops Four-Level Covert Authentication

Brandwatch Technologies, a Portland, Oregon-based developer of brand protection solutions, has introduced a new variety of its up-converting taggant technology that combines four levels of covert protection in one product. This, it says, is the only one marker that provides multiple simultaneous product identification and offers brand owners with a unique fingerprint to embed into their products or packaging.

The company, founded as Stardust Technologies in 2001, was acquired by a group of private investors in 2007, renamed and restructured with a new management line-up. It 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 identified simultaneously by the company’s Reveal detectors.

According to Steve Delepine, newly-appointed VP for Business Development, this product is unique and makes it possible to create a covert protective shield around a product that is statistically impossible to circumvent.

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 detectors. In addition to the visible response it produces when excited by an infrared source, this product also delivers an authentication signal, recognizable only by the Reveal detector.

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 a low concentrations.

The line of proprietary handheld detectors can isolate a range of taggants and detect multiple types simultaneously, ever through product packaging or at distances of up to 20 ft.
