摘要： An optical security component may include a first layer, a diffractive structure etched on the first layer, a second reflective layer covering the diffractive structure. The diffractive structure includes a first pattern consisting of a set of facets arranged to form various subsets of facets, each subset of facets including a facet with symmetry of revolution arranged concentrically. In each group of the subsets of facets, the subsets of facets present, in point regions defined by identical polar coordinates, a local alteration of the surface, such as to produce a recognizable graphic object for a given tilt angle and azimuth angle. The polar coordinates vary from one group to another, so as to produce a dynamic visual effect observable in reflection by change of tilt and/or azimuth.

摘要： The invention relates to a method for authenticating an illustration, comprising—encoding a message in the form of a two-dimensional barcode comprising blocks, each block coding a fragment of said message and comprising a set of coding sub-blocks, each sub-block comprising a set of binary elements. It is essentially characterised in that the encoding comprises prior steps consisting in:—defining or identifying a set of noteworthy points in the illustration,—calculating a set of attributes depending on certain at least of the noteworthy points,—selecting, among the calculated attributes, at least one attribute allowing a digital fingerprint to be defined—optionally compressing said digital fingerprint,—optionally signing said digital fingerprint by means of a cryptographic signature, and—recording in the message one among:—a set of at least one attribute,—the digital fingerprint,—the compressed digital fingerprint, and—the signed and optionally compressed digital fingerprint.

摘要： The invention relates to a plasmonic optical security component comprising two layers (2, 4) made of transparent dielectric material and a metal layer (3) arranged between said transparent dielectric material layers in order to form two dielectric-metal interfaces (31, 32). The metal layer is structured to form, on a first coupling region, a first periodic, two-dimensional coupling array (C1) which is capable of coupling surface plasmon modes, which are supported by said dielectric-metal interfaces, to an incident light ray, the first coupling array having a profile which does not have point symmetry in any of the directions thereof, and, on a second coupling region, a second periodic, two-dimensional coupling array (C2) which is capable of coupling surface plasmon modes, which are supported by said dielectric-metal interfaces, to an incident light ray, the second coupling array having a profile which does not have point symmetry in any of the directions thereof and is different from that of the first coupling array.

摘要： A method for processing a candidate digital image includes defining a set of noteworthy points in the candidate digital image. A set of at least three noteworthy points is selected to comprise a notable departure point, a notable arrival point, and a third notable point not aligned with the notable departure point and the notable arrival point. A set of at least one route, between the notable departure point and the notable arrival point, is defined. The route passes through all of the selected notable points. Local characteristics, of the pixels located along the route, are extracted. The signal, corresponding to the variation in the magnitude of the local characteristics as a function of each pixel along each defined route, is recorded in the form of a fingerprint.

摘要： An automatic desktop personalization device, for security booklet documents, includes a camera, an inkjet printing module, a laser marking module, a chip encoding module, and a transport mechanism. The inkjet printing module includes a printing head and is configured to print within a printing zone. The laser marking module is configured to mark within a marking zone. The transport mechanism is configured to automatically transport a security booklet document along a Y-axis linear direction, from an entrance to an exit, through printing positions and a marking position. The entrance and the exit are the same. The printing head is movable alongside an X-axis linear direction that is perpendicular to the Y-axis linear direction. The inkjet printing module includes the transport mechanism. The laser marking head is adjacent an inkjet printing bridge, such that the marking zone and the printing zone are at least partly combined.

摘要： According to one aspect, the invention relates to an optical security component intended for being observed under direct reflection. The component comprises a structure engraved on a layer of a material having a refraction index n2, a thin layer of a dielectric material having a refraction index n1 other than n2, deposited on the structure, and a layer of a material having a refraction index no other than n1, encapsulating the coated structure of the thin layer. The structure has a first pattern modulated by a second pattern such that, in at least one first region (61, 86), the first pattern comprises a low-relief with a first set of facets, the shapes of which are determined such as to generate at least one first concave or convex cylindrical reflective element, and the second pattern forms a first subwavelength grating acting, after depositing the thin layer and encapsulating the structure, as a first wavelength-subtractive filter; in at least one second region (62, 86), the first pattern comprises a low-relief with a second set of facets in which the shapes are determined such as to generate at least one concave or convex cylindrical reflective element (64), and the second pattern forms a second subwavelength grating acting, after depositing the thin layer and encapsulating the structure, as a second wavelength-subtractive filter, separate from the first wave-length-subtractive filter. Each subwavelength grating can be a zero order diffraction grating such as a DID.

摘要： An ID document comprises a receiving substrate in or on which an ink that is fluorescent under UV-A lighting is locally deposited, and a multilayer optical security component attached to a substrate. The optical component comprises a structurable layer and a reflective dielectric layer discontinuously deposited on the structurable layer in the plane of the component so as to produce patterns. The reflective dielectric layer has a relative transmission of at most 40% in the UV-B or UV-C range. The optical component also include an assembly of at least one layer including pigments that are fluorescent when energized by UV-B or UV-C. These are deposited on the reflective dielectric layer in a uniform or discontinuous manner in the plane of the optical component.
