Abstract

The graphic security pattern comprises areas (2, 3, 4, 5) containing respectively graphic lines designating the date of birth (2a), the family name and first name (3a), the place of birth (4a) and the special peculiarities (5a) of an identified individual. It also applies to the identification of objects of any kind.

Description

Method for producing a graphic security pattern and graphic security pattern obtained by this method.

The present invention relates to fiduciary documents such as personal identity documents or personal permits with or without photographs or fiduciary documents such as banknotes, securities, stocks, bonds, checks and the like.

We know that these documents must be protected against falsification and counterfeiting.

It is well known that one of the means of protecting these documents is printing on the document by conventional printing means such as letterpress, intaglio, offset, rotogravure, printing of security graphics fixed called guiHoches.

These graphic patterns have the particularity of being very difficult to reproduce by manual, photographic or computer means.

They are used for visual authentication or by optical enlargement processes of the originality of the documents on which they appear. The different categories of these graphic safety patterns are:

- the backgrounds occupying most of the surface of a document and in particular the locations thereof intended to bear printed indications; - the frames which, as their name indicates, surround the useful area of a document on which various indications are written;

- the strips which extend on at least one side of a document forming a margin; - the rosettes which generally occupy a central region of a document;

In addition, within a security motif, in particular for the backgrounds, local deformations can reveal a text or an image with a relief effect; we then speak of numismatic motif by analogy with the motif which is revealed by rubbing with graphite on a sheet of paper placed on a coin.

The design and production of these security features was first carried out manually, then by mechanical means such as guilloché lathes or gray-out machines. It is currently provided by computer means using a computer system consisting of a computer, appropriate graphics software and a computer tracing device such as a plotter, a graphic printer or a photocompo¬ seuse.

The fixed security graphic patterns generated by computer systems are designed using digital data, the number of which varies according to the system used and whose order of magnitude is from ten to a few tens.

The layout of these security patterns is used, together with other fixed information, for the manufacture of a fixed printer form intended for a printing machine in typography, intaglio, offset, gravure or serigraphy or any other process. fixed printing or reproduction process.

The result is a printed document with fixed security features.

Several means for designing and printing documents comprising fixed security reasons are known and do not relate to the present invention.

Certain fiduciary documents include both fixed information, fixed security graphic patterns and variable information.

In this category of documents we can cite, for example, personal identity documents or personal permits with or without photographs such as for example identity cards, passports, permits drive or fiduciary documents such as securities, stocks, bonds, checks.

The fixed or variable information in these documents is, for example, issuing State names, personal names, first names, dates of birth, places of birth, nationalities, addresses, designations of children, special distinctive signs, measurements, measurements, observations, comments, amounts, characteristics of companies, characteristics of issuers, beneficiaries as well as photographs, autograph signatures, fingerprints or drawings.

The computer systems for the design and creation of graphic security patterns work with mathematical models programmed in the software.

These mathematical models use a set of numerical or textual data.

The invention aims to create a graphic security motif which allows the precise identification of a document which carries it.

It therefore relates to a method of producing a graphic security identification pattern for a document, characterized in that it consists in entering, using a computer keyboard or a peripheral for scanning fixed information forming part of a basic graphic motif, entering variable information concerning the identity of the object with which the document is to be associated, to be constituted by calculation using automatic computer means from '' at least part of the fixed and variable information, digital information capable of mathematical combination with at least part of the digital data of the basic graphic pattern, to modify the shape of said pattern and to control using said information the printing a graphic security pattern resulting from the modification of the basic pattern using the said information and specific to the object with which the document is associated.

The subject of the invention is also a graphic security motif, intended for the identification of an object, characterized in that it comprises at least one graphic line arranged in at least one region and the shape of which corresponds to relative information. to the identity of said object. The invention will be better understood on reading the description which follows, given with reference to the appended drawings, given solely by way of examples and in which:

- Figure 1 is a plan view of a graphic security pattern according to the invention containing the identity information of a person;

- Figure 2 is a view similar to that of Figure 1 showing a graphic security pattern of another person living in the same locality as the person identified by the pattern of the person in Figure 1;

- Figure 3 is a view similar to that of Figure 2 showing a graphic security pattern of the same person as that identified by the pattern in Figure 2 but having changed place of residence; and - Figure 4 is a plan view of a passport open on the identification pages of its holder and bearing on its two pages the graphic security motif according to the invention.

In Figure 1 there is shown a graphical security pattern according to the invention in the form of a rosette containing graphical information relating to the identity of an individual.

The rosette 1 is subdivided into regions 2, 3, 4, 5 arranged approximately concentrically. In the example shown, the annular external region 2 contains graphic lines 2a which are reproduced periodically around its periphery and which correspond to the date of birth of the individual concerned.

The region 3 adjacent to the exterior region 2 contains graphic lines 3a corresponding to the surname and first name of the individual, for example Dupont Michel.

Regions 2 and 3 are separated from each other by a line 7 whose particular outline designates the place of residence of the individual, for example Montreuil.

Line 7a for the separation of regions 3 and 4 has a "homothetic" form from that of line 7 and therefore also contributes to the identification of the place of residence.

The region 4 adjacent to the region 3 towards the interior of the rosette contains graphic lines 4a designating the place of birth of the individual. The central region 5 contains graphic elements 5a characterizing the particular signs of the individual such as hair color, eyes, measurements, or the like.

This region is delimited externally by a contour 8 also delimiting the neighboring region 4 and corresponding to the country of nationality of the individual, for example France.

It will be noted that the border lines separating regions 2 to 5 from each other are defined by the graphic lines 2a to 5a contained in the corresponding regions and of which they constitute envelopes.

Figure 2 is a security graphic pattern in the form of a rosette containing information relating to the identity of another individual than that identified by the rosette in Figure 1 but living in the same locality, and having the same nationality.

The outer region 2 of the rosette 1 contains graphic lines 2b corresponding to a date of birth different from that designated by the graphic lines 2a of the rosette shown in FIG. 1.

Similarly, region 3 contains graphic lines 3b corresponding to the surname and first name of this second individual, for example Durand Jacques, which are different from lines 3a designating Dupont Michel in the rosette in Figure 1.

Regions 4 and 5 also contain graphic lines 4b and 5b respectively designating a place of birth and particular signs of Mr. Durand Jacques different from lines 4a and 5a giving the corresponding information on the subject of Mr. Dupont Michel.

On the other hand, the two people residing in Montreuil and being of French nationality, lines 7, 7a and 8 corresponding respectively to this information, are the same for the two rosettes.

FIG. 3 represents a graphic security motif according to the invention, relating to the same person as that identified by the motif in FIG. 2, namely Mr. Durand Jacques.

Consequently, the graphic lines 2b, 3b, 4b, 5b of regions 2 to 5 relating to the identification information of this person are the same as those in FIG. 2. On the other hand, Mr. Durand Jacques having changed domicile and now living the town of Sceaux, lines 7 and 7a separating zones 2 and 3 and 3 and 4 have a shape different from that of figure 2 which characterizes the town of Montreuil. FIG. 4 represents the pages of a passport bearing in clear the identification information of its holder.

On the left page 9 you can read the surname, first name, nationality, date and place of birth, of the holder, the date of issue and the expiration date of the passport.

There are also the signatures of the representative of the authority that issued the passport and that of the holder, as well as a photograph of it.

All of this information is variable information depending on the individual.

On the right page 10 appear the address of the holder, as well as his size, the color of the eyes which are also variable information.

At the bottom of each of these pages is a graphical security pattern 12 according to the invention similar to the graphical pattern described with reference to FIG. 1. Each of these patterns incorporates in graphical form all of the variable information shown in clear on the passport pages including graphic information corresponding to the holder's photograph. The graphic security patterns 12 form rosettes incorporated into the pages of the passport when it is completed and therefore personalize this passport by making it a practically unforgeable document containing the identification information of the holder. To produce a graphic security pattern according to the invention, the procedure is as follows.

The fixed and variable data are, as already indicated above, entered by means of computer systems for the design and creation of security patterns. operating with mathematical models programmed in software and using a set of digital data resulting from the conversion into digital form of clear data comprising numbers, letters and images.

Each security data set obtained by the operator by means of computer keyboards for numbers and texts or by means of image scanning peripherals for photographs, drawings, autograph signatures and fingerprints corresponds to a security reason. unique, this data can be stored by a computer.

The remainder of the presentation develops the originality of the invention, based on the fact that a document includes graphic security patterns of variable forms, the variability of which depends on the identification and authentication information of the document, thus allowing individual control visually or using an automatic control process and apparatus. These security reasons are designed automatically by a computer system.

For the design and generation of document information and variable security reasons, the operator enters fixed or variable document information, including photographs, autograph signatures, fingerprints, using computer keyboards or scanning devices. or drawings.

It is also possible to add automatic codes not visible on the document to these data, these codes being able to vary, for example, by date ranges of document issue.

Then, by calculation with automatic computer means, all or part of the fixed or variable information entered from the aforementioned document is included, including photographs, autogra- phes, fingerprints or drawings, as well as the automatic codes added, of the digital or textual information susceptible, by mathematical combination with all or part of the digital or textual data of a basic graphic security pattern formed from fixed information, to influence the shape of said pattern. There are computer processing algorithms which allow starting from an original text resulting from information entered by the operator, to construct a text or a set of transformed numbers which is unique for each text d 'origin. These techniques are used in particular in computer systems of cryptology.

The transformed text or set of numbers is then used to constitute parameters for varying the shapes of the variable security graphic patterns.

The shape can vary globally over the entire pattern or partially in a specific area of the pattern. This last zone can be fixed or variable in the pattern depending on the information in the document.

The resulting graphic security pattern is therefore variable depending on the fixed or variable information in the fiduciary document.

Depending on demand, this reason may or may not be unique per document within the scope of the document's fixed or variable information.

In addition, certain forms of the variable security graphic pattern can reveal, by simple inspection with the naked eye, fixed or variable information of the document such as for example the issuing State or the region of residence, individualization being obtained. by variable designs around these visually recognizable shapes.

This is how curves 7, 7a and 8 of the graphic patterns in Figures 1 to 3 represent respectively vely the place of residence, Montreuil and the country of nationality, France.

It is also possible, from all or part of the fixed or variable information of the document, to calculate numerical and textual control information, which information can then be printed on the document.

The variable security graphic patterns concern all categories of guiHoches with or without numismatic effect: backgrounds, frames, bands, rosettes.

The variable security patterns are then superimposed on the computer with the legible information to be printed, digital, text, photographs or drawings to form an overall image to be printed.

This image is then printed by a peripheral computer on a support pre-printed in a fixed or non-pre-printed way, in paper, plastic, self-adhesive label, on the front or on the back, in the mass, with or without inversion of image, in black and white or in color, the support being able to be opaque, translucent or transparent. All or part of the fixed or variable information of the document, all or part of the variable security pattern, all or part of the control information are printed on the support by computer means on a variable printing device in black and white or in colors, by electrostatic, inkjet, laser, thermal, sublimation or any other printing process by computer periphery. This last operation produces a document such as the passport of Figure 4, on the two pages 9 and 10 of which appears the rose 12 identifying its holder. This document can then be protected in welded envelopes, transparent or not, or stuck on a support.

In the example which has just been described, it has been considered that the invention is applied to the production of graphic security patterns in the form of identification rosettes for passports.

It is of course possible to apply the invention to graphic patterns of any shape such as funds, frames, banners to ensure the identification of objects, currency, stocks, oblivion gations or others without departing from the scope of the invention.
