Definitions

• the invention relates to a remote authenticated authentication document and a tester for authentication.
• Security documents such as banknotes, identity documents, driving licenses, bank cards, travel vouchers, vouchers, checks, gift certificates, etc. must be protected against copying and have elements allowing the verification in a certain way of the document.
• These elements are security threads, such as those described in documents US 61 321, EP 59 056, JP 63182497, holograms, indicated in particular in US 3,552,853, US 3,668,795, JP 2009015338, US 2009154813, optically variable inks, explained in the application WO 061 17271 or in patent US 6 472 455, optically variable films as described for example in JP 2009107259, and various markers incorporated in the body of the document or on its surface.
• the document must have a device which avoids the reproduction in the same way by the means accessible to everyone, that is to say by means of color reproduction and by scanning and printing with domestic means, such as inkjet or laser printer, - the document must have a means of remote authentication, the credit card or ticket may be placed on the dashboard of the vehicle or pressed against the windshield, that is to say at a distance of tester operated by the tester of the order of a few centimeters to a few tens of centimeters, or can be placed on a seat or side of the vehicle difficult to access for the controller, that is to say at a distance that can be greater than one meter, which represents a detection distance totally beyond the reach of known techniques,
• the tester meanwhile must be reliable, low cost and usable in all weather conditions that may be encountered by a controller for documents placed in all types of vehicles.
• RFID radiofrequency authentication
• a miniaturized electronic system is included in the document, or placed on its surface, and carrying information enabling the authentication, the device being remotely read by means of a suitable reader emitting a wave in the radio frequency range.
• RFID radiofrequency authentication
• Such a device is known for a long time and applied in the field of identity documents, including passports, and described in various patents, for example, to name only a few, in WO 0036555, WO 05098748, WO 05100021, WO 08119904, WO 2009007659, FR 2 899 000, EP 2 084 654, US 20030006121.
• RFID devices have several major difficulties that make them almost unusable in the present context:
• the device placed on the document in the form of a chip, for example, is expensive and impractical to install, very few printers are equipped to perform this operation simultaneously with printing, and the paper-making process generates an important additional cost for the document produced.
• the invention therefore aims to solve the specific problem stated above by proposing a new authentication system coupling a secure document with a specific pointer.
• the present invention thus relates to a security document that can be authenticated remotely under varying light conditions through a transparent or translucent physical barrier by means of a tester, as well as the corresponding tester and the test method, the invention is characterized by the fact that the document comprises at least one reagent developing a coloration under the action of spatially and temporally coherent laser-like radiation emitted by the tester, said radiation being called authenticator radiation, and in that said tester comprises means for accurately positioning said authenticator radiation on the security document at a distance between a few centimeters and more than one meter, the means for positioning the radiation on the document being a laser beam or an intense and narrow radiation said pointer radiation emitted in the area of perception of the eye, said tester thus emitting at least one visible radiation at a distance.
• the advantages of the system associating the secured document and the specific tester according to the invention are multiple: authentication is possible at a variable distance between the document and the tester and under varying lighting conditions, for all types of vehicles, the tester is cheap, reliable, simple to use and easy to transport,
• the document can be manufactured for a modest additional cost because only part of the document can be secured for authentication, and the processing can be performed by conventional printing means,
• the document can be processed to be reproducible by photocopying or scanning simultaneously with the processing used for the authentication and possibly even by applying a single printing ink containing all the products,
• the authentication method is simple, within the reach of all controllers and usable in all countries.
• - Security document any paper, plastic or laminate document containing elements preventing identical copying or reproduction by scanning and then printing, and / or, any document containing materials allowing its authentication and identification, tracers or markers for example, and / or any document containing chemical elements reactive to erasing agents, for example by causing coloration on the document, and / or any document emitting light emission under specific lighting or observation conditions.
• the authentication can be human or automated with suitable devices.
• Authenticable remotely a visualization of the physical identification reaction to certify the origin of the document without contact and at a distance that can be between a few centimeters and more than one meter, knowing that the authentication of a document is produced either by direct contact between the tester and the document, either at a very short distance of the order of a few millimeters to a few centimeters at most, the only authentication systems comparable to those described here are the RFID devices in which a chip is included in the document and a remote reader emits radiofrequency radiation allowing a response back of the document, such contactless systems allow reading of the identification information to several meters.
• Variable light conditions a document placed in a vehicle, such as for example a credit card or a parking ticket, is subject to ambient lighting, the vehicle may be in the sun outdoors and the document be strongly lit, or still inside a covered parking and dimly lit, moreover the windows of the vehicle can be partially reflective or tinted and the authentication of the document can therefore be affected, it is for example completely impossible to authenticate carrier documents prints with optically variable inks (OVD) or holograms under varying lighting conditions at a document distance greater than about 30 centimeters behind a transparent or translucent physical barrier.
• ODD optically variable inks
• Transparent or translucent physical barrier any type of glazing, tinted or not, partially reflective or totally transparent, used to make windscreens and windows more generally, in practice any closed environment allowing at least partial vision of the area containing the document to be authenticated and allowing the passage of a radiation as described by the present invention, it can thus be the passenger compartment of a vehicle but also a hermetically sealed box containing valuable elements and having a window, or other neighboring applications.
• the pointer makes it possible to visualize the zone where the authenticating radiation is located, this zone may be a point in the case of a highly focused laser beam but also a line, a cross, a circle, a disk, the tester emitting in the latter case a more or less open cone of light, ideally the marked area of the document, that containing the reagent, is reduced, and the positioning of the authenticator radiation must be precise enough so that the auditor does not waste too much time in positioning the radiation.
• the pointer radiation on the document may be at a point, a small disk or a cross, however the authenticator radiation will advantageously be a disk to easily cover the area to be authenticated by scanning a larger surface than that of the radiation pointer .
