Description

The present invention relates to the field of secure protective films for the protection of identity documents (passports, identity cards, driving licenses) and which are used to seal a page, paper, plastic or other, containing the personal information of the said identity document.

It is common to use a transparent protective film, which may include optical security elements (holograms for example), to seal personalization information printed on official documents such as passports. The protective films used for this purpose are generally reactivatable films having an activatable adhesive layer, surmounted by a transparent polymer layer acting as a protective layer. Thus, these films are activated when they are applied to the document to be protected in order to activate the adhesive property of the adhesive layer. Activation can be created by heating (thermo-activatable film) or radiation (for example ultraviolet). Such films include a certain number of optical safeties (UV prints, diffracting elements, holograms, variable inks, other special prints, ... widely described in the patent literature, for example US-2004/0239099 ) in order to allow authentication of the assembly consisting of a protective film and the document that it is supposed to protect. This component for sealing information is commonly called laminate.

These increasingly secure laminates are therefore one of the key obstacles to the production of a false identity document.

In the case of passports, it being understood that the invention concerns any document containing data sealed by a protective film, laminate and passport are manufactured by different stakeholders. The assembly is carried out either by the printer who integrates the laminate at the time of assembly of all pages of the passport, it is called "laminat sewn", either on the place of publication of the document, the personalization by printing the personal data to be sealed taking place according to the case either on the document or on the laminat before transfer.

The absence of any mark on the latter prevents individual management of these security components creating, inter alia, a security breach to the extent that the laminat may be lost, stolen or diverted for doubtful reasons before being sealed definitely on the document.

We already know, by the international patent application WO-2006/071732 an identity document structure comprising a main layer, a coating and a protective laminate. Information from the document holder is pre-printed on the main layer. The security coating is partially superimposed on the pre-printed information and represents personalized variable data to the document holder, such as an image, text or numbers. In this solution, the protective laminate is generic, not allowing individual management.

A first object of the invention is to allow such individual management of laminates so as to increase the security of laminated identity documents.

Another object of the invention is to secure the laminate, and thus the identity documents thus laminated, without complicating the process of manufacturing identity documents.

Other objects and advantages of the invention will appear on reading the description which follows.

At least one of these objects is achieved by the present invention by providing the laminates with identification numbers or other data enabling the unique identification of a laminate among a set of laminates. In particular, the subject of the invention is a transparent protective film for the protection of a surface, said protective film comprising the individualized and indelible inscription of a first unique film identification data. This inscription is made by the laminates supplier.

An individualized and simple management of laminates is thus made possible, like a simple management of identifiers. In addition, such laminates, if lost or stolen, can not be used simply for the realization of a false identity document since the apparent number remains easily identifiable. In addition, the pair consisting of this number and an identifier of the laminated document may constitute a reinforced security key.

Furthermore, the usual processes involving laminates do not need to be modified for the use of the laminates according to the invention. No additional steps in the use of these are necessary.

The identification data used may be of a different nature, provided that they can be generated in large numbers in order to ensure their uniqueness or quasi-uniqueness (use of an x number, two numbers are repeated every 10 ^x numbers). One-dimensional bar codes widely used, two-dimensional bar codes or alphanumeric sequences are particularly suitable for the implementation of the invention.

The invention also relates to an identity document of an individual comprising a support and such a transparent protective film, said protective film being laminated on the support so as to seal personal information of the individual.

The support is the paper or plastic base (PVC - polyvinyl chloride -, PET - polyethylene terephthalate -, PETF Polycarbonate etc ....) documents such as passport, identity card, driving license or any other a document assigned to a person, which is assigned a unique identification number, for example in the form of a bar code. As in the case of the passport, the personal data, for example the surname and forename, the date of birth, the nationality, the date of validity, a photo, ... are printed on this support, either directly or by the use of intermediate layers. For security reasons, these media now include optical security elements.

Generally, the protective films comprise a transparent polymer layer on one side, and an adhesive layer that is also transparent on the other, the latter allowing the laminate to adhere to the support, for example by thermo-activation. Optionally, the film is provided with one or more intermediate layers comprising optical security elements.

Compared to the solutions of the prior art, the identity document thus produced is more secure. In fact, the process of reconstituting a document or modifying an existing document by a malicious person is more complex: the latter must now obtain a blank protective film of the same type and provide the same with appropriate identification.

In addition, it is preferable to protect the laminate number from access by a third party, who can then modify it by chemical or laser methods. It is thus expected that said first identification data is mirrored on the face of the protective film adjacent to said support. The face adjacent to the support is that which is constituted by the adhesive layer. Thus, the number of the laminate can be written on this adhesive layer by processes adapted to the nature of the adhesive. Since this face is turned upside down when laminated against the document support, it is necessary to write this number or the data in reverse (by the mirror effect). In this way, when the identity document is rolled, the registered area is not directly accessible for a third party. The latter must either take off the laminate or pierce the upper layers (upper polymer layer and optionally the intermediate layers with optical security elements) to access the area. It is then easy to detect an alteration of the laminate and therefore a false document potential.

The registration methods which are particularly applicable to the invention are, by way of example, ink jet printing, thermal marking, laser printing, etc.

Advantageously, in the case of ink jet printing, an ink which penetrates the thickness of adhesive and is "absorbed" by said support under the effect of a stress during rolling can be used. The term "absorbed" means that at least a portion of the ink of the film is transferred to the support, the latter absorbing this ink in its paper or plastic structure. Different constraints can be applied to transfer this ink: thermal and / or mechanical transfer or by ultraviolet irradiation or by infrared irradiation. In particular, it is expected that this constraint is the same as that used for rolling, allowing in a single action to achieve both rolling and ink transfer.

The chosen ink can be visible or invisible in the visible and revealable spectrum under UV (ultraviolet) or IR (infrared) light.

As a result, an indelible mark of the number is transferred onto the paper medium and the subsequent laying of a new numbered film is then complicated by a need for precise positioning and alignment on the old inscription. In addition, in the presence of optical safety elements, the inscription of the number on the protective film must also be accurate with regard to the position of the optical security elements.

An alternative to mirror printing is that the protective film comprises a transparent outer layer, a transparent adhesive layer capable of being applied to said support, and a metallized surface representing a portion of the surface of the protective film, said metallized surface being disposed between said outer layer and said adhesive layer, and said first identification data is etched in said metallized surface. Etching is performed, for example, by laser marking. The metallized surface may also include optical security elements such as a hologram to complicate the reproduction thereof.

Furthermore, it is provided that said first identification data further comprises control data of said bar code or sequence. alphanumeric. For example, the number written on the film is supplemented with several control digits calculated according to known methods, for example according to a hash function (for example, SHA-256), a checksum per parity bit by redundancy or by cyclic redundancy (CRC). The presence of such data complicates the generation of coherent data identification and allows a first local verification of this consistency.

The invention also relates to a set of protective films comprising a single base having a plurality of protective films, each of the protective films comprising the registration of a first unique film identification data. According to a first variant, the protective films are arranged on said base, for example by means of a weakly adhesive layer. According to a second variant, the protective films are made in one piece with the base and are not cut yet.

The set of protective films may be in the form of a coiled coil, in the form of large format sheets comprising several films or in other independent formats.

This set is made by the laminates supplier and is easy to use for the personalization center or printer.

Optionally, said first identification data is generated randomly for said plurality of protective films. Therefore, the circulation of a number (or a barcode) does not inform other numbers also circulated through the same coil or the same set.

In a variant for simplifying the management of these identification data, it is provided that the first identification data comprises an alphanumeric sequence and the alphanumeric sequences are generated sequentially for said plurality of protective films, for example by simple incrementation.

In order to simplify the identification of the protective films in this set, it is intended to provide this set of marks. Holographic images present in the structure can be used as landmarks when the same pattern is applied at the same location for each of the protective films. When the assembly is continuous, that is to say a pattern is repeated all along without any information of any position of the protective film, it is envisaged to provide a regular marking on this assembly (coil), by example by printing a marker, a pre-cut or an identifiable sign.

In the solutions of the prior art, the verification of passports at a customs station is confined to verifying that the photo is that of the carrier and the printed data corresponds to the passport number in a central database. These systems do not make it possible to take into account, during verifications, new data inserted into the laminates. The invention also aims to solve this problem by proposing a system for managing a plurality of identity documents of individuals comprising a support and a transparent protective film laminated on said support so as to seal personal information of the individual, said protective film comprising a first identification data, the supports of said documents further comprising a second unique data of support identification, for example the passport number, said system comprising a first database, "the central database ", storing, in a single record for each document, at least the first protective film identification data, the personal information and the second media identification data. These records are accessible by customs officers without modifying their interface and require only a small adjustment of existing databases to add a dedicated field to the number of the laminate. In this way, checks at customs posts can be more complete.

The filling of this database, in particular the activation of the laminate number and its association with the passport data, is performed during a quality control step of the identity document, just before delivery. Various mechanisms make it possible to activate the laminate number, for example automatically simply because this number is present in the database and therefore used, or specifically by filling in a dedicated field (a flag for example) when it is desired to effective activation, for example, when delivering the identity document to its holder.

It seems desirable to provide additional control over these numbers of laminates available at the time of this control step in order not to validate a mis-seized or misidentified number. For this purpose, the system is furthermore provided with a second database storing the first identification data of the protective films and comprising, for each of the identification data, a status indicator taking a first value. when said first identification data is associated with a second identification data in a record of the first database and takes a second value when said first identification data is not present in the first database.

This second database is supplied by the laminates supplier who, as they are manufactured, provides the numbers of the laminates produced and delivered for circulation. In this database, the numbers are identified as good for production (first value of the status indicator), that is, the corresponding laminate is available for application to an identity document, and then identified as used (second indicator value) when they appear in the central database, that is, the corresponding laminate was used to roll an identity document. The consultation of this second database makes it possible to validate the availability of a number before its use and the putting into use of the corresponding passport or document.

This second database can simply be in the form of an electronic file containing all available numbers.

The control step is usually performed by an automatic scanner that reads information and data from identity documents. It is thus provided that the system further comprises means for scanning said identity documents, said means scan means being arranged to determine the first identification data of the protective film and the second identification data of the support and to associate, in the first database, said first identification data of the protective film to a recording comprising said second carrier identification data. Optionally, the scanner also verifies the accuracy of the personal information provided in the database with regard to those scanned.

The invention also relates to a method for manufacturing, by the laminate supplier, a transparent protective film of a surface comprising a step of generating a first unique identification data and a step of associating said first identification data to said protective film by writing said first identification data to one of the faces of said film. The transparent film previously mentioned is thus obtained.

It turns out that this method differs from known methods of the prior art since no registration of an identification data is performed on known laminates. These are used blank, as shown in the application WO-2006/071732 previously mentioned.

This method has the advantage of remaining simple while providing an additional degree of safety of such laminates.

As indicated above, the protective film may be provided with an activatable adhesive layer and the inscription is then carried out inversely (mirror effect) on said adhesive layer.

Alternatively, the protective film, or even the base from which said film is made, comprises a metallized surface disposed between the activatable adhesive layer and the outer protective layer, wherein said film identification data is etched into the metallized surface.

It is understood that preliminary steps of constitution of the transparent film can be provided, in particular to develop a multilayer structure provided with security elements as previously stated.

The invention also relates to a method of manufacturing an identity document of an individual comprising a document medium and a transparent protective film, the method comprising a step of recording personal information of the individual [ on said support or said transparent film] and a step of rolling the transparent protective film on the document support so as to seal said personal information, said transparent protective film comprising, during said rolling step, a first unique identification data of movie. The invention thus differs from the prior art in that it now applies, as laminat, a protective film with an identification number or equivalent.

The security advantages previously mentioned are thus provided by this method. The traditional processes are only slightly modified and rely on the same rolling machines, printing, ...

• FIG. 2 représente la structure d'un document laminé avec le film protecteur de la FIG. 1 ; et
• FIG. 4 est un exemple d'architecture système pour la gestion des laminats (films protecteurs) numérotés selon l'invention.

The invention will also be better understood with the aid of the drawings, in which:

• FIG. 1 and 3 show examples of non-rolled protective films according to the invention;
• FIG. 2 shows the structure of a laminated document with the protective film of FIG. 1; and
• FIG. 4 is an exemplary system architecture for the management of laminates (protective films) numbered according to the invention.

• un film porteur polyester 1 d'épaisseur comprise entre 10 et 50 µm ;
• une couche de détachement 2 qui équivaut à une cire ;
• une ou plusieurs couches de protection 3. Cette couche est la couche extérieure du produit après laminage. Elle peut donc être constituée de plusieurs couches présentant des caractéristiques de résistance mécanique et chimique. Cette couche est transparente ;
• une couche d'estampage 4, par exemple une couche thermoformable.

With reference to FIG. 1, a numbered protective film is made from a holographic laminating film comprising:

• a polyester carrier film 1 with a thickness of between 10 and 50 μm;
• a detachment layer 2 which is equivalent to a wax;
• one or more protective layers 3. This layer is the outer layer of the product after rolling. It can therefore consist of several layers having mechanical and chemical resistance characteristics. This layer is transparent;
• a stamping layer 4, for example a thermoformable layer.

This last layer 4 is stamped to form, under the action of heat, micro-structured zones constituting the optical security elements.

It follows a vacuum deposit, on the free surface of the stamped layer 4, a layer of a transparent material having a high refractive index optical 5, for example a transparent dielectric material including ZnS. This layer is also an optical and holographic security element.

Then, the lower surface of the refractive layer 5 is coated with a heat-reactive adhesive layer 6. Individual personalization of the laminates is provided by printing a number 7 on the lower surface of the adhesive layer. This impression is made in mirror.

The adhesive layer is transparent either by nature or after thermal activation or equivalent that is to say once laminated, this layer must be transparent so as to allow the vision from above of the protective film number 7 printed.

Finally, it is done finishing, typically the manufacture of coils / reels or components to be inserted in the passport. Optionally, the customization can take place before or after finishing.

FIG. 2 shows a document 8 laminated by the previous protective film. For this purpose, the personalized and finished film (see FIG.1) is placed on the substrate 8 of the document to be laminated, adhesive side on the document. A thermal activation of the adhesive layer 6 makes it possible to seal, on the document 8, the information printed on this document as well as the laminate number 7. The polyester carrier 1 allowing easy handling and protection of the film before application is removed at 2. The remaining layers are transparent so as to allow through-reading of the number 7 printed in mirror and thus read straight.

After rolling, only the layers 3 to 7 are thus transferred to the document to be protected.

Another embodiment of the film is shown in FIG. 3. The production starts from the same holographic rolling film comprising the layers 1 to 4 mentioned above. After the stamping step, vacuum deposition is performed on the free face of the stamped layer 4, aluminum or other metal 9. This deposit can be located on only a portion of the stamped layer. A demetallization is performed on all areas of the film to remain transparent to leave only the inscriptions 10. Many demetallization processes are known and can be used.

It follows a deposition step of a refractive layer 5 and an adhesive layer coating 6 as explained above.

The individual personalization step of the laminates is carried out by laser marking in the metallized layer of a number, for example by local destruction of the layer.

The finishes apply in the same way as before.

The protective film thus produced is applied in a manner similar to that described in relation to FIG. 2.

Toute tentative d'adultération du numéro se traduit donc par la destruction locale du passeport à l'endroit du numéro.

Various characteristics of the numbering of the laminate are envisaged:

• • sequential or random numbering using either alphanumeric codes (OCR font), 1D or 2D barcodes, possibly secure. This number can be a sequential or more sophisticated serial number with one or more control digits (hash function, checksum) ...
• Thermal marking, by ink jet, laser or other.
• • the position of the number can be done in a privileged place, under the picture (as shown in the diagram).
• • an indelible / indestructible numbering. In particular, the printed (mirror) on the inner face of the laminate allows the number after sealing of the laminate on the passport is trapped under the laminate. Any attempt to adulterate the number therefore results in the local destruction of the passport at the location of the number.

With reference to FIG. 4, the laminate manufacturer 40 performs the printing of the laminate numbers on the adhesive back of the coil 41 of protective films via a printer 42.

The manufacturer 40 then transfers (43) the roll of laminates numbered to the printer 44 which will roll these films on the official documents to be sealed. Transfer of the numbers made corresponding to the numbers carried by the laminates is also achieved (45) either via a database entered by the manufacturer 40 or via a dedicated digital file.

If necessary, the laminate manufacturer 40 can securely transmit (46) to its final customer 47 (not the printer, but generally the state service responsible for issuing the passports), a file 48 containing the all codes issued.

The printer 44 then transmits (49) the laminated documents to the end customer 47.
