Definitions

  • the invention relates to a device according to the preamble of the main claim.
  • Confidential information in particular those that are sent by mail, will be; like for example the PIN number to debit cards or phones, usually sent in a glued envelope that makes it apparent to the claimant, whether the confidential information before him has already read a third party unauthorized.
  • matrix printers have been used for printing, which label a paper in the envelope via a foil in the envelope, the outside of the envelope being blackened, so that no information can be read from the envelope itself. In any case, this can not be done without aids, which would be used only with greater expenditure of time.
  • unauthorized access is usually caused by tearing and is therefore noticeable after a short time.
  • an optically densely printed field (covered with a foil) is additionally provided with confidential information printed above it.
  • the information can be read or a partial information with a located on the back information to be completed.
  • the printing technique is comparatively alswenig, since it must be ensured that the information printed with film does not stand out from the dense printed field, (if not lifted even with criminal energy unauthorized persons with TESA film) and readily readable.
  • the invention is therefore based on the object to provide a method that allows to make accessible secret information with previously sent to the customer, or him also presented in the same letter in a detachable place aids.
  • a slightly removable silicone a so-called pressure silicone, between one after rear ejection punched out, wherein the information is printed on a transparent or translucent film, which is positioned in front of the tear-out, the film is advantageously matte and the tear-out, which is positioned behind the film having on its back the second line structure.
  • the translucent or transparent adhesive film may be made accessible to visualize printed information 14 printed on the film from its rear side, the sheet, by severing a perforation 18 in the sheet while separating out a sheet section 16 located behind the film 12. If necessary, the blade section can now be the aid on which the second line structure is located after being moved at an angle and preferably after the front and rear sides have been rotated.
  • the line structure may contain substantially parallel lines at least outside the areas to be read, the character representing areas and lines of different angles within the areas of the characters or the like.
  • a fingertip structure as a second line structure, in particular if this is present, for example, on a passport paper in a predetermined quality. If necessary, areas of the structure can be repeated several times to achieve the necessary fineness.
  • first line structure on a transparent area of a transmission carrier, and the second line structure on a separate device, which is placed underneath.
  • the second line structure can also be printed on a section in the same transmission carrier for visualization of the information printed in the first line structure, and a perforation or the like. for separation, wherein only after a separation is a read-enabling position (be it another angle, be it a twisting of the front and back of one of the line structures) below or above the first line structure possible.
  • first line structure is printed on a transparent area of a transmission carrier, under which a printed with Silkon printed section is detachable, on the back of the second line structure is printed, resulting in the procedure shown in the figures.
  • a second line structure which carries no information and is printed on a non-transparent area of a transmission carrier.
  • the information-bearing line structure may also be presented differently on a separate map or a tool that is placed under the second line structure.
  • the use of a valid, decrypting, but not information-bearing structure limited to, for example, a person or a time domain (e.g., a month) is conceivable.
  • the second line structure consists of finer lines with respect to the first structure, which lines run parallel to one another at least in partial areas.
  • the finer the structure the weaker the moiré effect, but the greater the density at the information site and around it.
  • the security can be increased since only the associated first line structure is made readable. This can be done, for example, by changing the line spacing while changing the line width. But also line length and curvature can be changed.
  • a further, second line structure for application to at least one other location on the form is calculated at the same time, which with the first line structure when superimposed creates a moiré effect which allows the man-made eye to recognize and read the information-carrying areas.
  • the printing process is preceded by, for each possible character, a vector-level area representation beyond the dimensions of the character, or as a bitmap to a printer memory of a graphics-capable printer. From there, it can be quickly retrieved and printed.

Claims (4)

  1. Dispositif pour la transmission d'une information secrète à l'aide d'une section (16), un accès de lecture à l'information secrète n'étant pas possible sans moyens auxiliaires spéciaux, avec
    - un support de transmission,
    - une zone transparente (10) du support de transmission qui porte l'impression d'un modèle et qui comprend une première structure de lignes,
    la première structure de lignes étant imprimée sur la zone transparente du support de transmission,
    la première structure de lignes comprenant dans les zones à lire et formant un signe (12) ou similaires de l'information, une modification qui se dessine de manière lisible en insérant au-dessous une deuxième structure de lignes (14),
    la zone portant l'impression d'un modèle étant imprimée avec un noircissement essentiellement régulier et
    la première structure de lignes (10) se composant de lignes essentiellement parallèles,
    caractérisé en ce que
    - dans les zones contenant les signes ou similaires de l'information, la première structure de lignes (10) est formée par des lignes ayant un angle différent et
    - la deuxième structure de lignes est imprimée sur une telle section (16) dans le même support de transmission et comporte une perforation pour l'extraction,
    une position sous ou sur la première structure de lignes (10) qui permet la lecture n'étant possible qu'après une extraction.
  2. Dispositif selon la revendication 1, caractérisé en ce que la première structure de lignes (10), laquelle est imprimée sur la zone transparente du support de transmission, peut être extraite sous la section (16) qui peut être imprimée au moyen d'une silicone et sur le côté arrière de laquelle est imprimée la deuxième structure de lignes (14).
  3. Dispositif selon l'une quelconque des revendications précédentes, caractérisé en ce que la deuxième structure de lignes (14) se compose de lignes qui sont plus fines par rapport à la première structure et qui s'étendent parallèlement entre elles.
