  • Identification particles and system and method for retrospective identification using spectral codes
    Patent number: 7038766
    Abstract: A system and method using reporter elements provides retrospective identification of articles. An article is marked with reporter elements such that the mark has a characteristic spectral response when exposed to energy stimulation. To verify the authenticity of the article, a reader scans the mark containing the reporter elements and obtains a spectral signature. The reader then compares the detected signature to the characteristic signature to determine the authenticity or identity of the marked article.
