Latest Patents
Ekman holds a patent for an "Encoded Security Document." This invention involves documents that are encoded with at least one thin, transparent coating that is normally invisible but possesses a readily detectable physical characteristic. These characteristics can include electrical conductivity, electrical impedance, electrical capacitance, and electroluminescence. The documents consist of a substrate on which at least one of the thin coatings is applied, along with conventional printing, preferably intaglio. The coating may be applied before or after the printing process, and it includes particles driven into the surface to a substantial depth. The uncoated substrate remains free of the detectable physical characteristic, while the coating is confined to a limited area of the substrate surface, serving as a code or pattern for identification. A second coating can be applied to mask the visual detection of the first coating, ensuring that the original document can be distinguished from a counterfeit.
