Definitions
- the invention relates to a discrete authentication device remotely feasible for products to be protected against counterfeiting.
- 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 06117271 or in US Pat. No. 6,472,455, optically variable films as described, for example, in JP 2009107259, and various markers incorporated into the body of the document or on its surface.
- the elements of the type of security son or elements included in the mass of the packaging can not generally be used because of the costs and / or the possibility of application, they are also not verifiable remotely.
- the product must have a device that avoids duplication by the means accessible to everyone, that is, by color reprographic means and by scanning and then printing with domestic means, such as an inkjet or laser printer, the product must have a means of remote authentication, the security element being able to be carried by a label, by the packaging carton or by the product itself, which product can be located at a substantial distance from the authentication device operated by the verifier, this distance can be of the order of a few tens of centimeters or greater than one meter, which represents a detection distance totally beyond the reach of known techniques,
- this authentication must be able to be performed under varying lighting conditions since the product to be verified may be inside the trade or in full sun outside, which is also unusual and very unfavorable compared to the usual conditions of verification,
- the authentication device meanwhile must be reliable, low cost and usable in all climatic conditions that may be encountered by a controller.
- RFID radio frequency authentication
- a system Miniaturized electronic device is included in the product or its packaging, and carries information enabling authentication, the device being read remotely by means of a suitable reader emitting a wave in the radio frequency range.
- RFID radio frequency 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 unfavorable in the present context:
- the device placed on the product in the form of a chip for example, is expensive and impractical to install, very few transformers are equipped to perform this operation simultaneously with printing,
- the invention therefore aims to solve the specific problem stated above by proposing a new authentication system coupling a rare security element with a specific authentication device.
- the present invention relates to a discretable authenticatable device that can be used remotely for a product placed in variable luminosity conditions by means of an authentication device, as well as the corresponding authentication apparatus, the device is characterized by the fact that it comprises at least one security element affixed to said product capable of developing a coloration under the action of a spatially and temporally coherent radiation, of laser type, emitted by the authentication apparatus, and by the fact that said apparatus authentication device emits radiation, in the form of at least one beam, for covering a large area by a simple unidirectional scanning at a distance of between a few centimeters and more than one meter, the radiation emitted by the authenticator device being located outside the area of perception of the eye.
- the advantages of the system associating the security element and the specific authentication apparatus according to the invention are multiple: the authentication is feasible at a significant distance between the product and the authentication device and under varying lighting conditions,
- the authentication device is cheap, reliable, easy to use and easy to transport,
- the authentication is discrete since no visible light is emitted by the authentication apparatus
- the treatment of the product can be carried out for a modest additional cost because only a small surface of the packaging or of the product itself can be secured for authentication, and that the treatment can be carried out by conventional means of 'impression,
- the authentication method is simple, within the reach of all controllers and usable in all countries.
- Authenticable remotely a visualization of the physical reaction of identification allowing to certify the origin of the product without contact and at a distance which 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 authentication device and the document, or at a very short distance from the order of a few millimeters to a few centimeters at the most, the only authentication systems comparable to those described here are the RFID devices in which a chip is included in the product or its packaging and for which a remote reader emits radio frequency radiation allowing a feedback response of the device, such contactless systems allow a reading of the identification information to several meters.
- a product placed on a display unit is subject to ambient lighting, the product may be in the sun outdoors and be strongly lit, or indoors on a shelving height and dimly lit, and The product authentication can therefore be affected, for example it is totally impossible to authenticate labels with prints with optically variable inks or holograms under varying lighting conditions at a distance greater than forty centimeters.
- - Security element it must be understood one or more constituent materials, one or more inorganic or organic pigments, dyes, polymers, generally chemical elements or various combinations capable of producing coloring under the action of radiation adapted.

- the security element producing the coloration is an anti-Stokes dye or pigment, emitting in the visible zone of the spectrum under the action of the radiation, the emitted color being perceptible at least 50 cm when the authenticate is placed in the sun and at least 1 m when placed in dim light or indoors.
- the authentication apparatus emits radiation formed by two spatially close and parallel laser beams, a laser emitting preferably in a range of between 254 nm and 380 nm, in the ultraviolet, and a laser emitting preferably above 850 nm, in the infrared, the security element then being composed of a mixture of reagents producing visible coloration under UV and anti-Stokes reagents, more advantageously still the colorations produced by the two beams will be different.
- Such authentication is very sophisticated and very difficult to counter for counterfeiters.
- the control of the product it can be considered to operate the two beams simultaneously and the product will show two different colors close in the control zone, or to activate the beams one after another to develop the different colors successively.
- the security element is advantageously little or not colored in daylight or in a non-annoying color when it is included in a printing ink, a varnish or a surface coating.
- the invention also relates to a method for authenticating a product remotely under varying lighting conditions by means of an authentication device, characterized in that: the product carries at least one security element developing a coloring under the action of spatially and temporally coherent radiation, of laser type, emitted by the authentication apparatus, which radiation is either a laser beam emitting infrared light, more particularly a light at 980 nm and the element staining-resistant security device being an anti-Stokes pigment, ie a laser beam emitting a light close to 360 nm and the security element developing the staining being a dye or a fluorescent or phosphorescent pigment, or two laser beams emitting a 980 nm and the other at 360 nm and the security element combines an anti-Stokes pigment and a fluorescent dye or pigment or phosphor escent, the authentication apparatus emits radiation to cover a large area by a simple unidirectional scanning at a distance of between a few centimeters and more than one meter, which radiation is located outside the
