Definitions

  • This invention relates to document security and in particular to tamper-evident forms for securely carrying information.
  • the invention has particular, but not exclusive, application to personal identification numbers (PIN) supplied to customers by financial institutions such as banks to enable the customer to validate a credit card or the like at the point of use.
  • PIN personal identification numbers
  • financial institutions such as banks
  • Secure transmission of a PIN to a customer is vital to reduce or prevent the fraudulent mis-use of credit cards.
  • the PIN is mailed to the customer using a tamper-evident form which enables the customer to detect if security has been breached by any unauthorised access to the PIN prior to receipt by the customer.
  • a tamper evident form for securely transmitting a PIN is disclosed in UK Patent No. 2 331 270 in which the form has an upper transparent lamina on which the PIN is printed and a lower non-transparent lamina carrying scrambling means which prevents the PIN being read when the upper and lower laminas are joined together wherein the lamina are separable to reveal the PIN printed on the upper transparent lamina.
  • This form relies on the presence of scrambling means so that the PIN is effectively hidden from view until the scrambling means is separated from the part of the form carrying the PIN.
  • the present invention seeks to provide a form for securely carrying information which does not rely on scrambling means to hide the information.
  • a form for securely carrying information including an upper lamina and a lower lamina releasably secured to the upper lamina, wherein the upper lamina is provided with perforations containing a filler material such that information printed on the filler material is revealed when the upper and lower lamina are separated.
  • the filler material in the perforations adheres to the lower lamina such that when the upper lamina is separated from the lower lamina, the filler material in the perforations remains adhered to the lower lamina and separates from the upper lamina with the lower lamina carrying with it the security information.
  • security information printed on the form is applied to the lower lamina through the upper lamina.
  • the filler material in the perforations changes colour where it is exposed to the printing such that, when the lamina are separated, the change in colour of filler material exposed to the printing reveals the security information.
  • the filler material is provided between the lamina and is received in the perforations of the upper lamina such that the filler material forms with the upper lamina a printable surface on which the information is printed.
  • the filler material may be provided by adhesive material employed to secure releasably the upper and lower lamina together.
  • the upper lamina is coated with filler material that is received in the perforations such that the filler material forms a, printable surface covering the perforations on which the information is printed.
  • the upper lamina may be secured to the lower lamina by adhesive applied to the upper lamina to be clear of the perforations and the coating of filler material fills the perforations and adheres to the lower lamina.
  • the filler material may be a printable material such as a cold set or heat set adhesive sealer material that can be dried by means of radio frequency (RF) , ultra-violet (UV) , infra-red (IR) or hot or cold air to produce a smooth, hard, non-tacky surface suitable for printing.
  • RF radio frequency
  • UV ultra-violet
  • IR infra-red
  • the filler material in the perforations of the upper lamina separates from the upper lamina and forms an array of raised pin heads on the lower lamina corresponding to the array of perforations in the upper lamina that carry with them the information printed on the pin heads exposed to the printing.
  • the PIN may be contained within an array of numbers printed on the form with the PIN being applied at a pre-determined location so that, when the lamina are separated, the PIN is revealed in a corresponding location of the lower lamina.
  • the lower lamina may be provided with a box at the pre-determined location that is concealed when the lamina are bonded together and which is exposed when the lamina are separated to allow the PIN contained within the box to be read.
  • the change in colour of the filler material exposed to the printing may enable the array of numbers printed on the form to be read while the form is intact but the PIN cannot be identified from within the array of numbers until the lamina are separated to reveal the location of the PIN on the lower lamina. This is completely different to UK 2331270 where scrambling means on the lower lamina prevents information printed on the upper lamina being read until the lamina are separated.

Abstract

L'invention porte sur une forme (1) destinée à supporter de manière sécurisée des informations sensibles telles qu'un numéro d'identification personnel (NIP), cette forme comportant un plastifié supérieur (2) et un plastifié inférieur (3) collés l'un à l'autre avec un adhésif (4) disposé pour remplir des perforations (8) du plastifié supérieur (2). L'adhésif (4) placé dans les perforations (8) forme des têtes d'épingle sur le plastifié inférieur (2) lorsqu'il est séparé du plastifié supérieur (3) de façon à révéler des informations imprimées sur la forme (1) dans la zone des perforations (8). Les informations révélées par les têtes d'épingle peuvent être un numéro d'identification personnel (NIP) appliqué sur une région prédéterminée de la forme (1) de sorte que ce NIP soit dissimulé jusqu'à la séparation des plastifiés (2, 3).
