Description

  • The The invention relates to a method and a device for verification of value documents, such as banknotes, identity cards, payment cards, Tickets, tickets or the like containing a substrate with at least a translucent region, wherein in at least a translucent region of the substrate a first Information is arranged. The invention further relates to a method and a device for verification or verification of valuables having a display, for example a computer, notebook or laptop, a cash register of a cash register or a handset.
  • Translucent Gain areas in security documents, such as windows in attractiveness. So there are already different functionalities for a window where information contained in the banknote about A self-certification will be made visible by the banknote for example, alternately over a white and black Background is held or with a laser pointer through the Window is illuminated through.
  • For example, the document describes WO 2006/018171 A1 a security element whose transparent or translucent substrate is provided with a mark of authenticity. In this case, a phase-shifting layer and a linearly polarizing layer are applied to a transparent film, wherein the main axis of the phase-shifting layer is rotated by at least 10 ° against the polarization direction of the linearly polarizing layer. The phase shift layer is formed of a birefringent or an optically active material, such as a liquid crystalline material, for example in the nematic or smectic phase. This authenticity mark transmits a first optical impression in transmitted light and, in reflected light in front of a predetermined and easily accessible background, a second optical impression which differs significantly from the first optical impression. This allows a simple and fast authenticity check, in which the security element is first viewed in transmitted light and then held in front of a predetermined background.
  • The Solutions of the prior art make it possible to that a certain authenticity mark can be recognized, a temporary one Change of stored information, for example, a monthly Change of information, however, is not possible.
  • Of the The invention is therefore based on the object, a fastness test of security elements in such a way that the counterfeit protection is further increased and a temporary change Hidden information is enabled.
  • These The object is achieved by the features of the independent claims solved. Further developments of the invention are the subject of dependent claims.
  • The The invention hereby comprises a method and a device for Verification of value documents, such as banknotes, securities, credit, Debit or ID cards, passports, certificates, tickets, lots and the like, labels, packaging or other elements for product safety. Here is in at least one translucent area of a security element a first Information arranged. According to the invention shows a separate display, such as a screen of a computer, notebook or laptops, a monitor of a cash register of a cash register system or a Display of a handset, at least partially a second information. Either in the first or the second information or in both pieces of information is hidden further information which for a viewer without aids or only barely recognizable and / or readable. According to the invention a verification of the security element by the first information in the translucent area of the security element the second information is placed and the hidden information recognizable as moiré pattern and / or as metamerism and / or becomes readable.
  • special Advantage of the invention is that the hidden information, for example includes the emission value or the currency of a banknote and thus as authenticity check at a POS terminal can serve. Here, the bill is on the display of the POS terminal and shows up for the cashier the information hidden on the banknote in plain text.
  • The invention further comprises a method and a device for verifying or checking valuables having a display, for example a computer, notebook or laptop, a cash register of a cash register system or a hand-held device. According to the invention, in this case a verification element is used which has at least one substrate with at least one light-transmissive region, wherein a first information is arranged in at least one light-permeable region of the substrate. Furthermore, a second information is displayed at least in areas by the display. In the first and / or second information, another information that is unrecognizable and / or readable to a viewer without aids is hidden. According to the invention, a Verification or verification of the object of value by the verification element is placed with its first information about the second information and the hidden information in transmitted light as a moiré pattern and / or as metamerism is recognizable and / or readable.
  • special The advantage here is that the hidden information, for example includes the name of the owner of the valuable item and thus Proof of possession in the event of theft or loss of the valuable item can serve. In this case, the verification element is about the display of the object of value is placed and shows up for the viewer, for example, a law enforcement agency the information hidden on the display in plain text.
  • One Display, d. H. a display device that alternately different Information or even no information can represent is preferred active display with its own lighting source, the display illuminated from the back. Likewise, the display can also be a passive display without its own illumination source, wherein a reflective surface that is at the back of the Displays arranged, daylight or room light reflected and so that the display illuminates indirectly. The invention is preferred also applicable to a novel transparent display whose Basic body of a viewer as (nearly) transparent is perceived. Here, the transparent display acts on itself as a (nearly) transparent window and those on the transparent Display displayed information as a single or multi-color turbidity the window represented by the transparent display influence or weaken light passing through.
  • The handset is, for example, a mobile phone, a digital camera, digital clock or a portable player for video or audio signals, eg. As an mp3 player or an I-Pod ® Apple® .
  • A Information in the sense of this invention is not always or barely discernible when a viewer leaves them without aids the surrounding information is not or only random and weak pronounced looks or perceives. In the same sense an information always not or only barely legible, if one Viewer the alphanumeric or textual content of the information without aids from the surrounding information not or only at random and weakly sees or read or not correct can interpret.
  • One Moiré pattern in the sense of this invention is an optical Appearance when radiating from two superimposed line or point grids with a parallel or nearly parallel light beam is observed. in this connection becomes a raster of uniform or uneven distribution of pattern primitives at least in a region of the substrate and the display, with the pattern primitives spaced apart are. Pattern primitives are preferably lines, d. H. elements whose width is much smaller than their length, and which are rectilinear, curved or kinked or formed have a combination of these three embodiments, or punctiform elements whose width is about the same size such as their length, such as points, circles or Squares. Are two grids that, for example, built almost identical can be superimposed, resulting in the overlay bright areas in certain areas and dark areas in other areas Make, the so-called moiré pattern.
  • Preference is given to the linear or punctiform grid
    • - Printed from a single or multi-colored paint and / or adhesive layer on the security element or the verification element or
    • - Imprinted in the substrate of the security element or the verification element or
    • - Produced by removal from a full surface applied coating.
  • in the the latter case consists of the coating applied over the entire surface preferably from a metal layer and the removal takes place by a partial demetallization of the metal layer. As demetallization come here a mechanical scraping, a laser ablation, a Washing method or other known methods of the prior art into consideration.
  • Of Further, the grid is preferably on the translucent Range of the object of value or the verification element covering or opaque colors applied. This has the advantage this increases the contrast of the moiré pattern becomes.
  • alternative The line or dot grid also becomes one Visually not or only barely visible lacquer and / or adhesive layer generated. For example, an adhesive over a printing process applied structured, also arise Moire structures by a scattering of the light on the generated adhesive layer.
  • If the lacquer and / or adhesive layer of the grid is preferably produced by opacifying pigments and / or opaque fillers such as TiO 2 , the lacquer and / or adhesive layer is visually not visible or only slightly visible in plan view. In review, ie against a background with the same or a similar color as the grid, that will Grid visible or recognizable.
  • One Moire pattern also arises when looking at the translucent Area of the security element or the verification element a grid of optical lenses is applied. On the display becomes a visually invisible and on the lens embossing coordinated micro-information shown. This occurs in particular Magnification effects on, with the micro-information due to the overlapping with the lenticular grid many times over is shown enlarged. For example, a shown on the display and not for a viewer recognizable or readable microfilm by the overlay magnified with a corresponding lenticular grid, that it is easy to read for the viewer.
  • metamerie For the purposes of this invention is a change of the light or the wavelength range of electromagnetic radiation occurring color inequality. This is how two metameric colors appear in a first wavelength range similar, have however, in a second wavelength range, a different one Color impression on. First and second wavelength range can be completely different or have a certain overlap area. metameric Color pairs are also referred to as conditionally equal.
  • The metameric colors or the metameric color pairs in this case have a comparable transparency, and preferably contain no opaque pigments and / or opaque fillers such as TiO 2 , ie are transparent.
  • In a preferred embodiment generate at least two metameric colors in a first wavelength range, preferably in daylight or similar artificial lighting, a same color impression. Through the display is now second Information light in at least a second wavelength range in which the at least two metameric colors at least produce two different color impressions.
  • alternative generate the at least two metameric colors in the first wavelength range at least two different color impressions. In this case will through the display as second information light in at least one second wavelength range delivered, in which the at least two metameric colors produce the same color impression.
  • Gives in both cases, the display alternately light different Wavelength as second information decreases, takes a viewer a change between a uniformly colored area and a surface of differently colored partial surfaces true. This change preferably takes place in a time sequence. For example, the display gives light of a first for one second Wavelength range and then one second long light from a second wavelength range, after which the sequence repeats itself regularly.
  • It however, they are also hybrids of moiré patterns and metamerism possible. For example, the pattern primitives the line or dot grid of metameric colors printed so that in one area there is hidden information using the moiré effect and another hidden Information is decrypted using metamerism can. Thus, in one area several different Information be hidden.
  • Of Further, first, second or the hidden information be executed in one or more colors. Preference is given here the Mustergrundelemen te a line or punctiform Raster multicolored executed, so that not only the usual light / dark moiré effect arises, but also about color mixing different colors or color gradations are possible.
  • One Translucent substrate in the context of this invention a substrate, the incident light in a certain proportion let pass. Sends light to one side of the substrate On, a certain amount of light will reach the other side of the light Substrate passed through and exits there again. The bigger the proportion of passing light relative to the incident Light is, the more translucent is the substrate. Leaves the substrate almost hits the incident light as in a window pass unattenuated, the substrate is transparent designated. If a lesser amount passes through the substrate, the substrate is called translucent. A substrate on the other hand, the no light can pass through, d. H. in which the Proportion of passing light relative to the impinging light Light is zero, becomes opaque or not translucent designated.
  • Especially advantageous is the transparent area of the substrate the security element or the verification element is a transparent or translucent plastic film, which is single or multi-layered is, or a transparent or translucent area within an otherwise opaque substrate, such as a card body or a paper.
  • The further information, which is not or only barely recognizable and / or readable for a viewer without aids, is either in the first or the second information or also in both hiding formations.
  • is the hidden information is at least partially within the first information, d. H. on or in the substrate is by overlay with the second information either all the hidden information visible or readable or only part of the hidden information. If only part of the hidden information becomes visible, you can by moving the second information further parts of the hidden Information becomes visible, so that the revealed part of the hidden information about the translucent Area of the substrate moves.
  • is However, the hidden information is at least partially within the second information and thus on the display, serves the first Information as a decoder, d. H. is by overlay with the first information, the hidden information visible or readable. It is possible, any, to the first To display information matched, second information on the display, so that also in a certain area either static or different varying or film-like information can be displayed are, but without the first information not visible or readable are. Preference can also be juxtaposition of Color changes of metameric colors or wandering dark and light Areas of the moiré pattern are shown.
  • The hidden information can also be found within the first and the second information. This will be the first information on the security element or the verification element in two or more sub-areas, with a sub-area contains the information to be verified. The second too verifying part is shown in the display and is such arranged that he is next to the first part to be verified is and does not or only slightly overlaps.
  • The Uploading the current second information to the display or on the electronics controlling the display via the Internet, by e-mail, with mobile phones also as SMS or via exchangeable Storage media, such as memory cards, flash cards or CDs / DVDs.
  • A preferred application of the invention results, for example, in proof of ownership of a mobile device, such as a mobile phone. On an identification card as a verification element is in a translucent Area presented a first information and on the mobile phone an image with a second information is displayed. Now puts the owner of the mobile phone the identification card on the display of the mobile phone, a hidden information becomes visible for example, contains the name of the owner. in this connection is in a first alternative way the hidden information in the first information on the identification card, the in order to be personalized to the owner. The second option is the hidden one Information on the display of the mobile phone, with the identification card for example, for all owners of mobile phones of the corresponding network operator or the corresponding manufacturer of the mobile phone is the same. Particularly preferred here is the hidden information stored on the SIM card of the owner or via the personalized SIM card after one generated certain procedures.
  • A another preferred application concerns lots with a profit functionality, on which there is a translucent area, in particular a window with a first information is located. The owner the lot receives for example over SMS or over E-mail a second piece of information that he sent on display a mobile phone or a computer. The owner now holds the lot over the display and puts immediately Determines whether the lot is a profit or a rivet. Here are the two ways that the one the hidden information in the lot itself or on the other in the second information sent by SMS or e-mail located. In the first case, the owner sends the lot to the initiator the winning action as proof, in the second case the proof is over the personalized SMS or e-mail provided.
