Abstract

The document has a sheet (11) comprising interference units receiving interference from magnetic field induced by an antenna from a base station. The units are formed by sheet impressions made by a conductive ink and block remote power feeding of the antenna, so that exchange of personal data is not performed. The units are inoperative when sheets (10, 11) form an angle greater or equal to 90 degrees.

Description

The present invention relates to a security document, such as a

  passport, driver's license, etc., which includes printed features related in particular to the identity of its carrier.

  The incorporation of a contactless integrated circuit (or chip) in such a document makes it possible to increase the level of security by securely storing therein variable information, relating in particular to the identity of the bearer, as well as biometrics elements characterizing it. Examples of such biometric information are: simple photography, facial recognition photography, fingerprint, iris print, hand or finger shape, voice print, retina recognition, signature dynamics, etc. Access to this information by proofreading makes it possible to ensure the authenticity of the document and its concordance with the holder, by visually confronting the biometric information with the holder, and with the printed data if necessary.

  The principle of contactless chip technology is based on the use of a radiofrequency (ie an electromagnetic wave) which is transmitted by a base station towards an antenna connected to a chip (or transponder) .

  This radio frequency makes it possible both to supply power to the chip (in one direction, from the base station to the chip) and also to convey the signals of the information (in both directions, from the base station to the chip and Conversely).

  Even if a majority of people are willing to accept that biometrics elements, by definition singularizing and discriminating, are incorporated into security documents in order to increase the general level of security, especially in airports, there are still public reluctance towards these new means of control and authentication.

  Indeed, when biometric recording and verification techniques are perceived as intrusive, people may feel directly assaulted.

  Fear of the "file" is also one of the legitimate concerns of citizens, that is to say, there remains a latent uncertainty hanging over the storage of biometric data in secure databases (to what degree?), Including the use is allowed to certain authorities (which ones?). But above all what crystallizes the fears of the individuals, it is to know that these databases could be pirated or, even worse, that it is possible without the knowledge of the holder, when this one circulates with his document, of have direct access to the chip data by any means for the purpose of illegal or even fraudulent exploitation.

  The present invention aims to remedy these difficulties, at least in part, by proposing a security document in which it is possible to store information including biometric in the chip according to ICAO (International Civil Aviation Organization) ), the reading of these being made possible only following a voluntary action of its bearer.

  Another purpose is to propose a document whose manufacturing technique is not fundamentally challenged compared to the traditional manufacturing technique.

  The present invention therefore relates to a security document, such as a passport, a driver's license, etc., which includes printed characteristics related in particular to the identity of its carrier, and which comprises at least a first and a second sheets adapted to pivot relative to each other to occupy multiple positions between a first extreme position called "closed", wherein said sheets are superimposed and form between them an angle of 0 and a second extreme position called " open "in which the sheets form between them an angle greater than or equal to 90, the first sheet being provided with a non-contact chip associated with an antenna, the pads of the chip being in contact with appropriate ranges of the antenna with a view to ensuring the remote power supply of the chip and / or the exchange of information, respectively with a radiofrequency transmitter / receiver system called "base station", by magnetic induction phenomenon.

  According to the invention, the second sheet is provided with means for disturbing the induced magnetic field received by the antenna from the "base station", these means blocking remote power supply totally or partially, thereby making the exchange of information impossible, and being inoperative when said first and second sheets form between them an angle greater than or equal to 90.

  It is therefore an original solution intended to alleviate some of the fears listed above in the introduction, by protecting the personal and / or biometric data against a consultation without the knowledge of the holder.

  The latter must therefore have a voluntary action on the document itself, by opening the latter, to make possible the reading of the data, when necessary, and only when it is necessary.

  According to other advantageous and nonlimiting features of this document - the inner face of said first sheet, that is to say that which faces the second sheet is provided with said non-contact chip associated with an antenna, while the inner face of said second sheet is provided with said disturbance means; the document comprises a third sheet which is provided with additional perturbation means, said first sheet being sandwiched between said second and third sheets; the disturbance means are located opposite or substantially opposite said transponder antenna when the sheets occupy said "closed" position; said transponder antenna consists of an impression of said first sheet with a conductive ink; said disturbing means consist of at least one printing of said second sheet, respectively of said third sheet, with a conductive ink; said ink is the same; said ink is screen printed; said transponder antenna is in the form of a track wound on itself; said printing consists of a series of concentric loops; said printing has the form of one or more windings closed on themselves; - said printing has the form of a flat; the document is in the form of a notebook, said antenna of the transponder and perturbation means being respectively integrated in the cover pages; the document is in the form of a notebook, said antenna being integrated in a page which is interposed between cover pages, at least one of which is provided with said perturbation means; - the said notebook contains at least one additional page; - The chip and its associated antenna, respectively the disturbance means, extend under a cover sheet, so that they are not visually identifiable.

  Other features of the invention will appear on reading the following description of certain non-limiting embodiments. This description will be made with reference to the accompanying drawings in which: - Figures 1 2 and 3 are simplified perspective views of three embodiments of a security document according to the invention, in this case a passport; FIGS. 4a and 4b, 5a and 5b are simple diagrams intended to explain the principle of operation of the technical means included in the security document.

  The following description will be made with reference to a security document consisting of a passport.

  However, this description is in no way limiting and must be understood the term "security document" in its greater generality, including including a driver's license, an identity card, a ticket and so on. The shaping of a passport generally comprises steps of assembling and sewing a booklet consisting of several sheets. In parallel is prepared the cover of the document, which includes the gilding of its visible face.

  The cover is then laminated on the cover pages of the booklet, that is to say the first and last sheets.

  Finally, the passport is broken, beaten and cut into the final format.

  With reference to the appended FIGS. 1 to 3, the passport according to the invention comprises printed characteristics, linked in particular to the identity of its wearer. These are invariable printed features such as "name", "first name", "size", "age", etc. but also of variable characteristics which change according to the identity of the wearer.

  This passport comprises at least a first and a second sheet 10, respectively 11, able to pivot relative to each other about an axis referenced X-X ', to occupy multiple positions between a first extreme position called "closed" in which these sheets 10 and 11 are superimposed and thus form between them an angle of 0 and a second extreme position called "open" in which these sheets form between them an angle greater than or equal to 90.

  The sheets 10 and 11 which have been reported can be constituted by the cover pages of the passport. However this is not mandatory.

  Moreover, these sheets can be mono- or multilayer.

  The pivot axis X-X 'of the first sheet relative to the second is constituted by a fold line.

  These first and second sheets may, in certain embodiments, consist of a sheet of larger size, folded in two.

  However, in other embodiments, it could be a comb binding or any other means for rotating the sheets relative to each other.

  According to the invention, the inner face 100 of the first sheet 10, (shown in the appended figures in vertical position), that is to say the face which is turned towards the second sheet 11, is provided with a contactless chip 2 associated with an antenna 3.

  By the term "internal face" is meant the side of the first sheet which is turned towards the second. However, this does not necessarily mean that this internal face is the "outermost" of the first sheet.

  In other words, this "internal face" can itself be covered with one or more sheets of cover. This aspect will be developed in the following description.

  The electronic component or integrated circuit commonly referred to as a chip may be referred to as the generic term "transponder" when connected to its antenna.

  This transponder stores in a remote memory the data forming part of the application in question and, on the other hand, carries out the control of the communication and ensures the connection by radio frequency.

  There is no physical electrical contact between the transponder and the base station (equipment containing all the controls capable of reading, writing and managing transponder information using radio frequencies) during the operation of the transponder. 'application.

  The chip is attached to the sheet by any suitable means known to those skilled in the art. This chip, in order to function, must draw its energy from the electromagnetic wave which supports the exchange of information.

  In order to have the electrical energy necessary for this operation, the chip must be connected to an antenna, that is to say a winding of conductive material of the current.

  When the antenna is placed in an electromagnetic field, a magnetic induction phenomenon generates in the turns of the antenna a current and a voltage which serve to supply the chip with power.

  Preferably, but not necessarily, the antenna consists of an impression of the first sheet 10 with a conductive ink. This ink is advantageously constituted by either a polymeric resin added with atoms, silver, gold, copper or any other electrically conductive metal, carbon, or even their combinations, or else intrinsically organic polymers. conductors, dissolved in a suitable vehicle.

  The deposit of the ink on the sheet is for example made by screen printing. But any other printing technique to achieve finesse and thicknesses required for the proper operation of the device are also conceivable.

  The pads of the chip are in contact with appropriate ranges of the antenna 3, in order to ensure the remote power supply of the chip and / or the exchange of information with respect to a base station, as is well known .

  According to the present invention, the inner face 110 of the second sheet 11 is provided with means for disturbing the induced magnetic field received by the antenna 3 from the base station.

  With reference to this second sheet, the expression "internal face" must be understood in the same way as that specified above, with reference to the first sheet.

  In the embodiments of FIGS. 1, 2 and 3, these means 4, 5 respectively 6 are located facing or substantially facing the antenna 3 when the sheets 10 and 11 occupy the closed position.

  In other words, in this position, the disturbance means 4, 5 and 6, and the antenna 3, are superimposed.

  Still in accordance with an essential characteristic of the invention, the disturbance means 4, 5, 6 block the remote power supply totally or partially, thereby making the exchange of information mentioned above impossible and, moreover, means are inoperative when the first and second sheet 10 and 11 form between them an angle greater than or equal to 90.

  Preferably, these disturbance means are constituted by at least one printing of the second sheet 11 with a conductive ink.

  More preferably, the ink used is the same as that used for the antenna 3 and the deposition is done in the same way, preferably by screen printing.

  Thus the ink deposits for the realization of the antenna on the one hand, and disturbance means on the other hand, can be performed simultaneously during the manufacture of the passport, resulting in a real economic advantage offered by the implementation of the present invention.

  In the embodiment of FIG. 1, the disturbance means 4 consist of the printing of a series of non-contiguous concentric loops 40.

  In FIG. 2, the printing 5 has the shape of a solid surface which occupies substantially the same surface as that of the antenna 3.

  In FIG. 3, the printing 6 has the form of a winding of turns closed on itself, which occupies substantially the same surface as that of the antenna 3. In a variant, several coils nested within each other are envisaged.

  In both embodiments Figures 1, 2 and 3 are shown in transparent form, intermediate pages 12 which form part of the passport and do not interfere with the operation of the means according to the invention.

  In Figure 4a is shown schematically a passport according to the invention which is shown in a position such that the sheets 10 and 11 form between them an angle of 90.

  The station base BS produces an alternating magnetic field creating in the medium where it develops a magnetic induction B. This magnetic induction causes the appearance of a magnetic flux at a given distance through the surface which is based on the contour the antenna (cl) being proportional to the number of turns).

  The instantaneous variation as a function of time of the magnetic flux (4) produces the appearance of a potential difference (ddp) induced across the antenna.

  This ddp processed by resonant circuits of L, C type tuned to the carrier frequency emitted by the BS station base is the power supply source of the integrated circuit 2. The remote power supply takes place and the exchange of data is thus made possible.

  In FIG. 4b, (illustrating the closed oppositions of the document) the perturbation means 4, 5, 6 present on the sheet 11 spatially disturb the induced magnetic field B, either by absorbing all or part of its energy, which reduces the remote power supply. transponder at zero or a threshold that does not allow its proper operation, or by actually preventing its establishment without interference through the turns of the transponder antenna, especially by reflection phenomenon.

  The means 4, 5 and 6 can therefore be described as inhibitory devices or "radio inhibitors".

  Preferably, the first sheet 10 is presented so that the plane of the antenna is orthogonal to the propagation of the field.

  It is therefore easy to understand that it is therefore necessary that the holder of the passport opens it so that the pages form an angle greater than or equal to 90, so that the information contained in the chip are read. This situation can occur when the wearer comes to a check, either spontaneously for an automatic examination, or because he is invited by an authorized staff.

  On the contrary, when the passport is closed and, moreover, is stored in a garment bag or inside a bag, the disruption means fully fulfill their function, so that the information contained in the chip can not be read without the permission of the holder.

  In a variant of the invention illustrated in FIGS. 5a and 5b, the conveyor is integrated in a page 10 which is interposed between first page 11 and last page 11 'of coverage.

  To allow the operation of the transponder, the sheet 10 must form an angle of at least 90 with each of the covers 11 and 11 '.

  This corresponds to the position of Figure 5a. The disturbance means are inactive and do not interfere with the operation of the transponder.

  In contrast, in the "closed" position of FIG. 5b, the disturbance means 30 block the remote power supply.

  As described above and preferably, the chip and its associated antenna on the one hand, and the magnetic field perturbation means on the other hand, placed on the pages 10 and 11, are themselves covered with a sheet, they are thus protected against deterioration and, moreover, are not visible to the naked eye.

  In the event that someone degrades the passport, it would also irreversibly degrade the chip, the antenna and the means of disruption since they are hidden.

  In the description that has just been given, the antenna and the disturbance means are printed on the passport. In conjunction with a variant embodiment not shown, they could be integrated into a support called "inlay", which would then be reported (glued) to the corresponding sheets of the passport.
