Abstract:
This invention relates to validation of security papers, documents, banknotes, artworks and brand products. The technical results of the invention are the implementation of the cost-effective and mass-producible security labels with the hidden polarized mono- or multi- color images without any visible outlines of such polarized images, the method of forming said labels, as well as the method of the product authenticity verification with the assistance of the security labels claimed. The claimed security label comprises a sequentially disposed metallic reflective layer and an optically anisotropic transparent substrate, as well as an element able to change optical properties of the said substrate in order to form a hidden polarized image. The element changing the optical properties of the substrate is made in the form of mask that covers a face side of the substrate by the same metallic material that is used for the reflective layer on a reverse side of the substrate. In the second version the claimed security label comprises at least two transparent superposed optically anisotropic substrates, each mask is performed using a solid fill printing method with blank spaces made in accordance with the hidden image graphics. These blank spaces are made in such way that they may coincide or may not coincide for adjacent optically anisotropic transparent substrates, and for each section of such optically anisotropic transparent substrates with the blank spaces in their masks laying under the blank space of the top substrate mask the total optical thickness, Formula (I), where d i thickness of optically anisotropic i th substrate; i - from 1 to N depending on the number of the transparent substrates mentioned above; n ei - the index of refraction for the extraordinary light beam in the i th substrate; n oi - the index of refraction for the ordinary light beam in the i th substrate, has been selected to ensure that for the light passing through a polarizer to the security label the transmittance T of the correspondent section has a maximum on the preset wave length λ, where λ is the light wavelength in a vacuum.

Abstract:
A wireless communication device (200) and method (300) with intelligent authentication. The method (300) can include the steps of: capturing (310) a first image of an object; determining (320) whether the object matches a predetermined criteria; projecting (330) ultra violet illumination at the object and capturing a second image of the object; and comparing (340) the second image to a reference file, to determine purported authenticity of the object. The device (200) and method (300) can provide an improvement in minimizing the spread of counterfeit currency and use of non-authentic documents, in near real time and in a portable device.
Abstract:
The present application describes products incorporating non-visible information for identifying the source of the product, the identity of the product, or the identity of an asset to which the product is affixed or for which the product serves as packaging. The product includes a base layer onto which information is encoded using a non-visible information encoding. An obscuring layer may also be provided. The obscuring layer is provided separately from the base layer and obscures the non- visible information encoding from view. The obscuring layer may be a card face, a thin material film, a latex sheet, foil, varnish, or opaque ink printed over the variable magnetic code. A method for incorporating a non-visible information into a product is also provided.

Abstract:
An image acquisition device is provided for use in determining whether a test object is an authentic object having an authentication image applied to an authentication image area thereof. The authentication image includes indicia formed based on authentication parameters. The image acquisition device comprises an image capture arrangement configured for capturing a digital image of a target area of a test object. The image acquisition device further comprises a data processor having an image processing portion configured for receiving and processing the digital image to produce a processing result. The processing result may be established at least in part using one or more of the authentication parameters.
Abstract:
Die Erfindung bezieht sich auf ein Sicherheitssystem, basierend auf der optischen Identifikation von hochspezifischen, räumlich erscheinenden Mikrostrukturen in einem Substrat mittels eines in das Substrat integrierten mikrooptischen Vergrößerungssystems. Bekannte Systeme offenbaren ein Mikrolinsenarray mit einer Vielzahl von optischen Achsen, das über einem Mikrobildarray angeordnet ist und ein nur virtuelles räumliches Gesamtbild erzeugt. Für ein hochkomplexes räumliches Erscheinungsbild, das nicht oder nur unter extremem Aufwand nachahmbar ist, ist die Erfindung dadurch gekennzeichnet, dass das mikrooptische Vergrößerungssystem (05) eine einzige optische Achse (15) aufweist und die Mikrostruktur direkt von der räumlich ausgebildeten Oberfläche zumindest eines einzelnen Mikro- oder Nanopartikels (02) gebildet ist, der in einem transparenten Einbettungsmedium (03) auf der optischen Achse (15) des mikrooptischen Vergrößerungssystems (05) eingebettet ist. Bei der Erfindung wird somit die reale Dreidimensionalität von speziellen Mikro- oder Nanopartikeln (02) mit hochspezifischen Mikrostrukturmustern auf ihrer Oberfläche, die nicht nachahmbar sind, genutzt und durch die Mikrolinsenvergrößerung als öffentliches Sicherheitsmerkmal zur Verfügung gestellt.
