Definitions

  • This invention broadly relates to security and protection systems for documents subject to counterfeiting or falsification attempts and, more particularly, it relates to a combined synergistic system which, by exploiting the combination of various protection systems, each individually valid and effective, at least to a certain extent, enables a finished product to be obtained with an absolute security level or, anyway, a security level much higher than the security level achievable as a sum of the security levels of the individual systems.
  • a further system provides for incorporating metal wires with the thickness of the paper.
  • OSI Overt Security Image
  • GSI Covert Security Image
  • This protection system comprehends the protection against falsifications and colour photocopies as well as the protection of the data amenable to be modified.
  • This protection can be easily checked not only by a person skilled in the art, but also by a user having no particular training, because it is inherent in quite evident manner in the image itself.
  • this printing technique is quite different from the latent imaging technique as presently practiced in the value-paper field, consisting of an image hidden in the drawing (as it is implicitly comprehensible from the term "latent"), such latent image being only evidenced when it is observed under certain angles and only when it is illuminated by grazing light. In other words, the effect is hidden and it is made visible only under determined conditions, only known to persons skilled in this specific field.
  • the technique according to this invention can be assimilated to the technique of holograms in which the image is not hidden, but it is in any manner and under any observation angle apparent, but, when its supporting sheet is displaced, the image varies thereby exhibiting a
  • Such a technique can be performed by: - combining particular patterns together, so as to enhance the visible effect under any condition;
  • This technique as adopted in this invention distinguishes from the holograms which are overposed on the paper and, as such, are removable therefrom and reapplicable to another document, and it allows to obtain an effect directly incorporated with the paper itself, without any possibility that it is removed and reapplied to another document.
  • a printing process namely a chalcographic printing process. It is carried out by performing engravings in the printing plates and subsequently by filling said engravings with ink, said ink being subsequently transferred to the paper by application of a very high pressure (as typically employed in chalcographic printing machines) that deforms the paper so as to force it to penetrate into the tiny engravings of the plate, with contemporaneous ink transfer.
  • a very high pressure as typically employed in chalcographic printing machines
  • the plate segments that have been filled with ink transfer the latter to the paper. These segments will have a relief that can be perceived also by the touch, provided that the engravings realized in the plate have a sufficient depth.
  • the perceived colour is the sum of the colour of the walls (for instance, sky-blue, if a sky-blue ink has been used) and of the colour of the paper (for instance, yellow, if a yellow paper has been used), and consequently the observed colour will be green (because, in the additive colour technique, the sum of a yellow colour and of a sky-blue colour furnishes a green colour).
  • Still other variations can be obtained by means of ridges of variable heights, obtained by realizing engravings of variable depths in the printing plates.
  • the protection of modifiable data such as the serial number
  • the serial numbers or broadly the 25 data it is desired to protect against any alteration, to be printed for one half on the positive band and for the other half on the negative band.
  • the printing colours as used in this invention can have a high coverage figure or can be transparent, so as to achieve the following effects.
  • 30 A In the case of a high coverage colour, the erasure operations turn out to be very difficult, in view of the fact that, it the colour existing between said printing grooves is to be eliminated, it is absolutely necessary to etch the paper structure, which, of course, makes the tampering visually apparent.
  • 35 B In the case of a penetrating colour, it can be observed that the colour penetrates to a still deeper level into said grooves, so that the erasure difficulty still increases, thereby making any tampering even more apparent.
  • This protection system provides, in the first place, for drawing according to predetermined patterns all those parts that it is desired to protect against erasures, for instance the Serial Number of bank cheques, or any writing it is desired to make alteration resistant, and like.
  • This drawing step which practically entails embossing of the paper, can be carried out either before or after the serial numbers have been inserted.
  • the latter procedure is surely more effective, in view of the fact that it deforms the characters themselves of the printed serial number according to the embossing pattern.
  • the characters become extremely difficult to be erased, because the ink is absorbed in the depth of the deformations and it becomes unreacheable not only by abrasive mechanical means, but also by chemical solvents.
  • this protection system based upon latent images provides for inserting, upstream of the standard magnetic band of certain documents, for instance, a letter in CMC7 characters, that can be magnetically read by means of an algorithm, possibly an intelligent algorithm, previously agreed upon with the client.
  • This algorithm can be inserted into electronic computers and it can be varied, for instance, according to pre-established number ranges. Only by way of exemplification, the case can be mentioned of a client with whom it has been agreed to utilize a letter as suffix 13 of the serial number, according to the following scheme, that is one of the innumerable possible schemes:
  • the above mentioned letters can also be illegible with naked eye, so that only magnetic readers can decode them.
  • the position of the literal or numeric algorithm is such that these documents are anyway read, without interferences or noise caused by the concerned literal suffix .
  • the algorithm can also be intelligent and such that it can be computed only by an electronic computer and it can be changed according to ranges previously agreed directly with the interested client.
  • One of the innumerable intelligen algorithms can be only by way of exemplification as follows: - only the odd figures are taken from the serial number, starting from the first figure that is unity (one),
  • each of these figures is multiplied by each figure of a predetermined fixed number (such as 97246), namely the first figure is multiplied by 6, the second figure is multiplied by 4, the third one is multiplied by 2, and so on,
  • the complement to the subsequent ten (that, of course will be a number between 0 and 9) is considered as intelligent algorithm.

Abstract

L'invention concerne un système de protection combiné pour des documents présentant une ou plusieurs protections choisies dans un groupe OSI (Overt Security Image/Image de sécurité manifeste) à images de sécurité apparentes et/ou dans un groupe CSI (Covert Security Image/Image de sécurité invisible) à images de sécurité latentes, ledit groupe OSI comprenant: (I) une protection contre les falsifications et les photocopies en couleurs, basée sur l'adoption de procédés d'impression dans lesquels on utilise les phénomènes de réflexion de la lumière, conjointement avec des motifs et des gravures particuliers, pour donner une apparence différente à différents détails des motifs; (II) une protection des données modifiables par l'impression de différentes parties desdites données modifiables sur des parties du document présentant différentes caractéristiques de réflexion de la lumière. Ledit groupe CSI comporte: (I) le dessin ou la gravure en relief des parties du document que l'on veut protéger contre l'effacement, en particulier celles contenant des données numériques, en fonction de motifs particuliers; (II) l'insertion d'une lettre supplémentaire lisible magnétiquement ou d'un numéral en amont de la bande magnétique standard, la lettre ou le numéral variant en fonction d'un algorithme personnalisé; (III) l'application d'une encre sympathique invisible à l'oeil nu, conçue pour devenir visible définitivement lorsqu'elle est mise en contact avec des substances activantes spécifiques; (IV) pour les documents dont la négociabilité doit être limitée, l'enlèvement irréversible d'une partie prédéterminée de ceux-ci.
