  • Patent number: 12288438
    Abstract: A method for determining the authenticity of an object by marking the object with a first luminescent material with a first decay behavior over time, marking the object with a second luminescent material with a second decay behavior that differs from the first decay behavior, excitation of the luminescent materials with a light pulse, measuring the afterglow intensities of both luminescent materials temporally after the excitation with the light pulse, forming a difference signal or identity signal from the afterglow intensities measured over the elapsed time, determining the time of a zero crossing of the difference signal or the time of the identity signal of a comparator, comparing the time determined by the zero crossing or by the identity signal with a setpoint value.

  • Patent number: 11886947
    Abstract: A method for uniquely marking an object, wherein a random distribution of individual pigment domains is applied to a surface of the object, and wherein a list of distances of the individual pigment domains from one another is measured and stored in a database. Also a corresponding method for identifying an object by: capturing an image of the pigment domains, identifying the two-dimensional coordinates of each pigment domain captured in the image, determining the two-dimensional distance of each pair of two pigment domains and/or the angle of each triplet of pigment domains, storing the distances and/or angles determined in the step before in a list, storing the list in the database, the list enriched with meta-information about the manufacturing and/or finishing parameters of the object, applying a database identification as an information unit to the surface of the object, the information unit uniquely assignable to the database.

  • Publication number: 20230383130
    Abstract: A security ink contains at least a first fluorescent and phosphorescent pigment and a second fluorescent pigment, wherein the security ink if excited with a first wavelength emits radiation with a first emission spectrum, if excited with a second wavelength emits radiation with a second emission spectrum being different from the first emission spectrum, and after the excitation has been terminated emits radiation with a third emission spectrum being different from the first emission spectrum and being different from the second emission spectrum.
