    摘要： The invention relates to a method of authenticating a magnetically induced mark applied on a substrate including magnetically oriented partially reflective platelet-shaped magnetic or magnetizable pigment particles, with a portable device equipped with a light source operable to deliver visible light, an imager, a processor and a memory, the method comprising calculating, with the processor, a corresponding average intensity I of the light reflected by the partially reflective platelet-shaped magnetic or magnetizable pigment particles and collected by the imager at corresponding viewing angle θ, storing the calculated average intensities of the reflected light and corresponding viewing angles to obtain a reflected light intensity curve I(θ), comparing the stored reflected light intensity curve I(θ) with a stored reference reflected light intensity curve Iref(θ) for said magnetically induced mark, and determining whether the magnetically induced mark is genuine based on a result of the comparison.

    摘要： An imaging system (200) for generating a measure of authenticity of an object (10) comprises a dispersive imaging arrangement (30) and an image sensor arrangement (60). They are positioned so that, when electromagnetic radiation (20) from the object (10) illuminates the dispersive imaging arrangement (30), the electromagnetic radiation is dispersed and imaged by the image sensor arrangement (60). The imaging system (200) is configured to then generate a measure of authenticity of the object (10) depending at least on a relation between the imaged dispersed electromagnetic radiation and reference spectral information. The invention also relates to imaging methods, computer programs, computer program products, and storage mediums.

    摘要： Authenticating a mark having a marker that emits light under illumination, involving an obtaining of a light spectrum from the mark, the light spectrum having values, each value indicating a light intensity of the light emitted from the mark for a corresponding wavelength, an applying of a set of rules onto the values of the light spectrum to obtain a first result indicating whether the mark is authentic or not, an applying of statistical processing onto the values of the light spectrum to obtain a second result indicating whether the mark is authentic or not, and a generating of an output result indicating whether the mark is authentic or not from the first result and the second result.

    摘要： An imaging system (200) for imaging and generating a measure of authenticity of an object (10) comprises a dispersive imaging arrangement (30) and an image sensor arrangement (60). They are positioned so that, when electromagnetic radiation (20) from the object (10) illuminates the dispersive imaging arrangement (30), the radiation splits out in different directions into at least a non-dispersed part (40) and a dispersed part (50), and those are imaged by the image sensor arrangement (60). The imaging system (200) is configured to then generate a measure of authenticity of the object (10) depending at least on a relation between the imaged dispersed part, the imaged non-dispersed part, and reference spectral information. The invention also relates to imaging methods, computer programs, computer program products, and storage mediums.
