Definitions

  • This difference o f reso lution allows the overlapping either partial or complete of the two patterns . Furthermore, this difference of reso lution can make it impossible for a device adapted for one of the reso lution to read the pattern with the other resolution.
  • the first pattern is rendered illegible to a user who does not already know the alphabet used to create the pattern, that is to say, who does not know the valid and invalid states of the symbo ls .
  • the fact that the symbo ls inscribed on the article cannot be determined makes the pattern impossible to find.
  • the invalid state or states of the symbo ls in particular make the reading practically impossible without the knowledge of the alphabet.
  • At least one valid state of at least one symbol of said identification pattern represents a digital information item.
  • the valid states of each symbo l o f the pattern may respectively represent binary values o f a digital information item.
  • the pattern is therefore particularly suited to encrypting binary information.
  • each invalid state of a symbo l is different from the valid states of any one o f the symbo ls o f the alphabet.
  • PI can be used in order to form a second pattern according to the invention.
  • PI' may be applied on a surface in order to be read under a second reading condition.
  • the different invalid states may comprise, for each of their groups Gil to GI14: no dot El, a single dot El, two dots El or even three or four dots El, such as, for example, for the group GI14.
  • the non-dots E2 are arranged at the positions left free by the dots El .
  • P2 is assigned one of the two valid states Vil or Vi2. This assignment is made randomly or in a specifically determined manner according to an information item that the reference pattern is required to represent.
  • Figure 2 shows, as an example, two possibilities of representation denoted P2' and P2". It will obviously be understood that a large number of other possibilities can be envisaged with the two valid states Vil and Vi2.
  • the two representations P2' and P2" differ by the use, for certain symbols of the reference pattern P2, of different valid states.
  • the symbol A' located in the top left corner of the representation P2 is represented in the form of the valid state Vil corresponding to the group Gl of the alphabet AT2.
  • the same symbol A' in the top left corner of the representation P2" is represented in the form of the valid state Vi2 corresponding to the group G2.
  • the first valid state Vil corresponds to the value 1
  • the second valid state Vi2 corresponds to the value 0.
  • the first symbol SP1 of the determined pattern PI corresponds to the value 1
  • the second symbol SP2 of the determined pattern PI corresponds to the value 1
  • the third symbol SP3 of the determined pattern PI corresponds to the value 0
  • the fourth symbol SP4 of the determined pattern PI corresponds to the value 0.
  • the first four symbols represent the decimal value 12.
  • a partial alteration o f a certain number of symbo ls o f an identification pattern can therefore be tolerated. This represents an affirmation o f the robustness o f the identification o f the identification pattern.
  • the robustness o f the identification o f the identification pattern can be enhanced by having a number o f representations (identical or not) of the reference pattern on the article. The need to have to place the article according to an exact position when the detector is fixed is thus avoided.
  • a black or colored ink is used for printing the first pattern and a second ink is chosen in the group formed by black or colored IR transparent ink is used for printing the second pattern.
  • Typical black or colored ink printed by inkj et or laser techniques are already known by the one skilled in the art and so ld under the market by know providers such as Hewlett Packard, Olivetti i-j et or Canon.
  • Typical black or colored IR transparent ink are also known by the one skilled in the art and described in EP 1789505B 1 or WO2007133533 A l .
