    Abstract: The invention allows using a commodity hardware (e.g. a smartphone, a tablet, a computer . . . ) to automatically establish a high level of assurance authentication and identification of any government-issued identity document of a user (e.g. identity card, driving license, passport . . . ) and link that to digital identity counterpart. Moreover, the invention allows personalizing a material-based security feature provided of said government-issued identity document to create a link between the identity document and its data content that can be read by such a commodity hardware and serves as reliable credential for accessing a service once the material-based security feature has been authenticated via the commodity hardware and a signature of the identity data of the user has been authenticated by a server of an authority.

    Abstract: Authenticating a mark comprising a marker that emits light under illumination, involving an obtaining of a light spectrum from the mark, the light spectrum comprising 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.

    Abstract: 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.

    Abstract: A security element comprising a first and a second pattern PAT1 and PAT2 formed in or on a substrate, the first pattern PAT1 being formed by a first material INK1 applied to a first region of the substrate, the second pattern PAT2 being formed by a second material INK2 applied to a second region of the substrate, said first and second regions of the substrate overlapping,wherein a part of the first pattern PAT1 overlaps with a part of said second pattern PAT2, the first material INK1 comprises a first luminescent dye or pigment DYE1, which upon excitation by electromagnetic radiation falling within an excitation wavelength range λ1a of the first luminescent dye or pigment DYE1 is capable of emitting electromagnetic radiation in at least one first emission wavelength range λ1e, and the second material INK2 comprises a second luminescent dye or pigment DYE2, which upon excitation by electromagnetic radiation falling within an excitation wavelength range λ2a of the second luminescent dye or pigment DYE2 is capable of emitting electromagnetic radiation in at least one second emission wavelength range λ2e, and said first emission wavelength range λ1e of the first luminescent dye or pigment DYE1 overlaps with the excitation wavelength range λ2a of the second luminescent dye or pigment DYE2, so that upon irradiation with electromagnetic radiation within the excitation wavelength range λ1a of the first luminescent dye or pigment DYE1 the second luminescent dye or pigment DYE2 is excited, in the area of overlap of the patterns, to emit electromagnetic radiation in the emission wavelength range λ2e.

    Abstract: 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.
