GonioLabs' technology presented at bilateral security conference EASC09
Lindstrand, M., A Novel Security Hologram General Purpose Optical Scanner
The gonioLabs' DOVID Reader (GDR) is based on a spatially, angularly and chromatically resolved high dynamic range of reflectance measurement principle. The GDR is able to in detail and quantitatively capture the perceptually most important characteristics of DOVIDs. The close link between the principal components of information gained by the GDR and the ditto gained by visual perception motivates the GDR to be of unique relevance for the mutually significant first, second and third line inspection modes.
The ability to perceptually relevant characterization of DOVIDs opens the door to technology-neutral product standards, facilitates unambiguous forensic communication, and greatly enhances detailed visual inspection. In short: improved security.
Diffractive Optically Variable Image Devices (DOVIDs), or "security holograms", is increasingly often a vital component of security documents e.g. passport documents. Despite being a cornerstone security component, the DOVIDs lack one important feature: a meaningful characterization. As DOVIDs are primarily used to facilitate first line (human) inspection, the principal components of a meaningful characterization would ideally include the principal components gained by visual perception. Unfortunately instruments have been unable to capture the perceptually important characteristics of DOVIDs.
The recent development of a new DOVID general purpose scanner by gonioLabs of Sweden effectively reduces this shortcoming. The gonioLabs' DOVID Reader (GDR) is based on a spatially, angularly and chromatically resolved high dynamic range of reflectance measurement principle. The GDR is able to in detail and quantitatively capture the perceptually most important characteristics of DOVIDs. The close link between the principal components of information gained by the GDR and the ditto gained by visual perception motivates the GDR to be of unique relevance for the mutually significant first, second and third line inspection modes.
The ability to perceptually relevant characterization of DOVIDs opens the door to technology-neutral product standards, facilitates unambiguous forensic communication, and greatly enhances detailed visual inspection. In short: improved security.
2009, 2 October 11.15-12.15, session ”Technology for critical infrastructure protection”
Euro-Atlantic Stakeholder Conference, Stockholm, Sweden on 1-2 October 2009, organised by The Swedish governmental agency "Swedish Civil Contingencies Agency" (MSB) in cooperation with the US Department of Homeland Security Science & Technology Directorate was part of a bilateral agreement between US and Sweden on cooperation in science and technology for homeland security matters.
