Description

Identification system of an object bearing an identification mark and associated method

The present invention relates to a system for identifying an object bearing a mark, as well as a method for identifying such an object.

It is common to identify objects with a mark allowing a user to verify the authenticity of the object, or to check if the object has been reported as stolen. Such markings are in particular used for objects with high added value that may be stolen or have technical characteristics that are difficult to obtain and whose counterfeits may not fulfill the required functions.

Such marks include, for example, a serial number of the object, or a coded identifier such as a barcode for storing a large amount of information on a small area of the object.

In order to preserve the aesthetic properties of the object, and to prevent the mark being spotted and intentionally destroyed, this mark is often inscribed on the object with invisible ink under the normal conditions of use of the object. For example, inks that are transparent to visible light but emit visible light when illuminated by ultraviolet radiation are frequently used. In order to reveal them, specific illumination systems such as ultraviolet lamps are generally used.

These systems are then limited to the identification of comprehensible marks by humans, such as serial numbers or specific symbols. As a result, the amount of information carried by the mark is limited, the absence of the mark being, for example, interpreted by an observer as proof that the object has been infringed. If the targeted application requires more information, then it is common for the observer to note a serial number of the object to later compare it to an external database such as a stolen object database. The process of identifying the object is therefore long and complex. The object of the invention is therefore to propose a system for identifying an object bearing a mark that is easy and quick to use. For this purpose, the invention proposes a system for identifying an object bearing an identification mark, the mark being designed to emit visible radiation when the mark is illuminated with ultraviolet radiation.

The system is characterized in that it comprises: • a mobile device comprising an imager and a first radiofrequency communication module, • a lighting device configured to be fixed to the mobile device in an operating position and comprising a module lighting device capable of emitting ultraviolet radiation, and • an identification device, and in that the mobile apparatus is configured to control illumination of the object by the illumination device with ultraviolet radiation, to acquire an image of the mark when the object is illuminated, and to transmit to the identification device, by radiofrequency communication, a submission message containing the image, the identification device being able to identify the object from at least of the image.

The invention also relates to a method for identifying an object bearing a mark, the mark being intended to emit visible radiation when the mark is illuminated with ultraviolet radiation, the method being implemented by a system comprising a mobile device, a lighting device and an identification device.

The method is characterized in that it comprises steps of: a) fixing the lighting device to the mobile device in an operating position, b) controlling, by the mobile device, an illumination of the object, by the illumination device, with ultraviolet radiation, c) acquisition, by the mobile device, of an image of the mark when the object is illuminated by ultraviolet radiation, d) transmission by the mobile device , the identification device, by radiofrequency communication, a submission message containing the image, and e) identification of the object, by the identification device, from at least the received image.

The characteristics and advantages of the invention will appear on reading the description which follows, given solely by way of nonlimiting example, and with reference to the appended drawings, in which: FIG. 1 is a diagrammatic representation of an object bearing a mark and a system for identifying such an object according to the invention, the system comprising a lighting device; FIG. 2 is a perspective view of the lighting device of FIG. 1, comprising flexible branches for fixing the lighting device to the mobile device; and FIG. 3 is a flow chart of an identification method according to the invention, implemented with the identification system of FIGS. 1 to 3.

An object bearing a mark 15 and an identification system 20 has been shown schematically in FIG. 1. The object 10 is a physical element manufactured or transformed by man. For example, the object 10 is a manufactured object such as an electronic device. In another example, the object 10 is a package, a jewel, or a container such as a bottle.

Alternatively, the object 10 is a natural object such as a stone or a living being such as a fruit, a vegetable, or an animal.

The mark 15 is an information-carrying sign on a surface of the object 10. The mark 15 is able to identify the object 10. This means that the mark 15 is suitable for allowing the identification system 20 to transmit to a user U of the identification system 20at least one information relating to the object 10.

The mark 15 comprises for example a predetermined pattern. By "predetermined pattern" is meant a mark 15 of any shape, the presence or absence of which enables the identification system 20 to obtain information relating to the object 10. For example, the mark 15 is an associated logo to a company that makes the object 10.

Advantageously, the mark 15 is able to identify the object 10 in a unique manner. This means that the mark 15 is associated with a single object 10.

The mark 15 comprises, for example, a set of alphanumeric characters, such as a serial number of the object 10.

Alternatively, the mark 15 is a coded mark intended to be interpreted by a machine, such as a barcode or a matrix code. The matrix code is, for example, a QR code (of the English Quick Response Code or QR Code). QR codes are frequently used matrix codes consisting of black and white squares that correspond to the zero and one digits, respectively. Each square contains in this case a bit of information. According to another variant, the mark 15 comprises a set of symbols such as numbers organized in the form of a square grid.

The mark 15 is intended to emit visible electromagnetic radiation Rv when the mark 15 is illuminated by ultraviolet electromagnetic radiation

Ru. The mark 15 is preferably invisible to the human eye when it is not illuminated by ultraviolet light Ru.

For example, the mark 15 comprises organic molecules such as chromophores capable of emitting visible electromagnetic radiation Rv when the mark 15 is illuminated by ultraviolet electromagnetic radiation Ru. A chromophore is a group of atoms having one or more double bonds, and forming with the rest of the molecule a sequence of conjugated double bonds, that is to say an alternation of double and single bonds. Alternatively, the ink comprises crystals having rare earth atoms, such as europium atoms. The crystals preferably have dimensions less than or equal to a few hundred nanometers.

The first computer 65 is configured to transmit the control message Mc to the lighting device 30 via the first communication module 50.

The first computer 65 is further configured to determine a geographical position P of the mobile device 25. For example, the first computer 65 comprises a GPS receiver.

According to the example of Figure 2, the housing 70 is substantially parallelepipedic. The housing 70 has a front face 105, a rear face 110 opposite the front face 105 in a fixing direction Df, and four side faces 115. Each face 105, 110, 115 is flat.

As a variant, the front face 105 is convex, that is to say that the housing 70 has a thickness measured in the fixing direction Df from a point of the front face 105, and that the thickness measured at from a point in the center of the front face 105 is greater than the thickness measured from a point of the front face 105 in contact with a side face 115.

The width I is measured in a second direction Y perpendicular to the fixing direction Df and the first direction X. The width I is between 50 mm and 70 mm.

The lighting module 75 is carried by the front panel 105. The lighting module 75 comprises a light emitter 120. Preferably, the lighting module 75 comprises a first light emitter 120 and at least one second light emitter 120. According to the example of FIG. 2, the lighting module 75 comprises three light emitters 120.

Each light emitter 120 is capable of emitting ultraviolet radiation Ru. Each ultraviolet radiation Ru has a set of wavelengths A.

At least one wavelength of the set of wavelengths is an ultraviolet wavelength. Ultraviolet wavelengths are wavelengths between 100 nanometers (nm) and 400 nm. Preferably, each wavelength A is an ultraviolet wavelength.

Each radiation Ru has a nominal wavelength An. The nominal wavelength An is the wavelength for which the radiation Ru has a maximum intensity.

The radiation Ru corresponding to each light emitter 120 is different from the radiation Ru of each other light emitter 120. This means that each set of wavelengths A corresponding to a light emitter 120 is different from each other set of wavelengths A corresponding to each other light emitter 120. Preferably, the nominal wavelength An of each radiation Ru is different from each other nominal wavelength An.

For example, each nominal wavelength An is selected from the group consisting of 254 nm, 280 nm, 312 nm, 330 nm, 365 nm, 500 nm, 650 nm and 950 nm.

Each light emitter 120 is detachable relative to the housing 70. Each light emitter 120 is configured to be attached to the housing 70 in an attachment position by the user U and to be detached from the housing manually by the user U.

The first light emitter 120 is controlled independently of the second light emitter 120, that is to say that the control message Mc generated by the mobile device 25 comprises a list of light emitters 120, comprising at least one indicator In a corresponding light emitter 120, and the second computer 80 is configured to control the transmission, by each light emitter 120 whose indicator In is contained in the list of emitters Le, the corresponding ultraviolet radiation Ru. The indicator In is, for example, a number of the light emitter 120, or the nominal wavelength An of the emitter 120.

Preferably, each light emitter 120 is controlled independently of the other light emitters 120.

Each light emitter 120 comprises at least one light-emitting diode. For example, each light emitter 120 is a straight bar having a plurality of light-emitting diodes. In this case, when each light emitter 120 is in its respective fixing position, each light emitter 120 is parallel to the other light emitters 120.

The second computer 80 includes a first memory 125 for storing an identifier Id of the lighting device 30.

The first memory 125 is a read-only memory, that is to say that the first memory 125 is configured so that the identifier Id can be read by the lighting device 30 but can not be modified by the device. For example, the first memory 125 is a PROM memory. A PROM (Programmable Read Only Memory) is a type of ROM that can only be programmed once.

In a variant, the first memory 125 is an EPROM memory. An EPROM (Erasable Programmable Read-Only Memory) is a type of ROM that needs to be exposed to ultraviolet radiation for reprogramming.

The first memory 125 is provided to keep the identifier Id even when the first memory 125 is not powered. The identifier Id is able to identify the lighting device 30 uniquely. The identifier Id is, for example, a serial number of the lighting device 30.

The second communication module 85 is configured to exchange information with the first communication module 85 by radio frequency communication.

Each leg 90 is configured to collaborate with the other leg 90 of the same pair to secure the light device 30 to the mobile device 25 in the operating position.

When the illuminator 30 is in the operating position, the imager 60 is exposed, i.e., the illuminator 30 is not interposed between the imager 60 and the object 10 when the secondary face 45 is directed towards the object 10. The imager 60 is then able to acquire an image Im. When the lighting device 30 is in the operating position, the rear face 110 bears against the secondary face 45.

Each branch 90 extends from a corresponding side face 115. The lateral face 115 corresponding to each branch 90 is parallel to the lateral face 115 corresponding to the other branch 90 of the same pair. Each branch 90 is flexible, that is to say it is provided to be elastically deformed by the user U to fix the lighting device 30 in the operating position.

Each branch 90 includes a fastener 135, a resilient portion 140 and a hook 145. The fastener 135 is adapted to secure the branch 90 to the housing 70. The fastener 135 is configured to allow a respective rotation of the branch 90 relative to the 70. For example, the fastener 135 is traversed by a pin 148 for fixing the fastener 135 to a respective lateral face 115, the fastener 135 being able to pivot around the corresponding stud 148.

The elastic portion 140 connects the hook 145 to the fastener 135. The elastic portion 140 is a strip made of an elastomeric material. The elastic portion 140 is provided to exert on the hook 145 an elastic restoring force tending to bring the hook 145 closer to the fastener 135.

The hook 145 is made of a rigid synthetic material. For example, the hook 145 is made of acrylonitrile butadiene styrene. Acrylonitrile butadiene styrene is a thermoplastic polymer having good impact strength, relatively rigid, light and moldable. The hook 145 has a first end portion 150 and a second end portion 155.

The first end portion 150 is configured to bear against the main face 40 of the mobile device 25 when the lighting device 30 is in the operating position. The first end portion 150 is provided for exerting, under the effect of the elastic restoring force generated by the elastic portion 140, a pressure force on the main face 40 of the mobile apparatus 25 when the lighting device 30 is in the operating position. The pressing force tends to press one against the other the secondary face 45 of the mobile apparatus and the rear face 110 of the lighting device 30.

The first end portion 150 is covered with a flexible material such as felt, able to prevent the first end portion 150 from damaging the main face 40.

The second end portion 155 is opposite to the first end portion, that is to say that the point of the hook 145 furthest from the first end portion 155 is carried by the second end portion. 155. The energy storage member 95 is configured to electrically power the lighting module 75, the second computer 80 and the second communication module 95. The storage member 95 comprises a battery and a coil to enable charging the battery by induction. The battery is a rechargeable battery. For example, the battery is a flexible battery with organic radicals. Batteries of this type can store a high energy density per unit area out with a very low volume.

In a variant, the energy storage member 95 also comprises an interface for connecting an electrical conductor for charging the accumulator.

The identification device 35 is a data processing device such as a computer or a computer server. The identification device 35 includes a second memory 160. The identification device 35 is configured to identify the object 10 from the image Im.

The second memory 160 is adapted to store a list Lm of marks 15 and a list Li of identifiers Id.

The list of marks Lm contains a plurality of computer representations Ri of marks 15.

For example, if a mark 15 has an alphanumeric character string, the corresponding computer representation Ri is a list of characters contained in the second memory 160. Each character of the character list Le is associated with a single character of the mark 15. and identical to the corresponding character of the mark 15.

In the case where the mark 15 comprises a two-dimensional grid of digits, the corresponding computer representation Ri is a set of several character lists Le.

In the case where the mark 15 is a coded mark such as a matrix code, the corresponding computer representation Ri is a computer file containing the same information as the matrix code.

Each mark 15 of the list of marks Lm corresponds to an object registered in the identification system 20.

The list of marks Lm further includes a description D of each registered object. The description D includes for example the name of an owner, a serial number, a date of manufacture, a place of manufacture, or a state of the object 10. The state of the object 10 is for example a "stolen" condition when item 10 has been reported by its owner as stolen.

The list of identifiers Li comprises a plurality of identifiers Id each corresponding to a lighting device 30 recognized by the system 20. A lighting device 30 recognized by the system 20 is a lighting device 30 authorized to exchange information. For example, a recognized lighting device 30 is a lighting device 30 whose user U has previously registered with an operator of the identification system 20.

The operation of the system 10 is described below.

A flow chart of an exemplary method of identifying an object 10 is shown in FIG.

The identification method comprises a fixing step 200, a control step 210, an acquisition step 220, a transfer step 230, a selection step 240, a transmission step 250, an authorization step 260, an identification step 270, a communication step 280, a refusal step 290 and a failure step 300.

During the fixing step 200, the lighting device is fixed by the user U to the mobile device 25 in the operating position.

During the control step 210, the control message Mc is generated by the mobile device 25 and transmitted to the lighting device 30 by radio frequency communication. The mobile device 25 thus controls the illumination of the object 10, by the lighting device 30, with the ultraviolet radiation Ru.

During the acquisition step 220, at least one light emitter 120 emits the corresponding ultraviolet radiation Ru. Each light emitter 120 whose corresponding In indicator is included in the list of emitters Em emits the corresponding ultraviolet radiation Ru. The light emitters 120 whose corresponding In indicator is not included in the list of emitters Le do not emit the corresponding ultraviolet rays Ru.

Preferably, during the acquisition step 220, the ultraviolet rays Ru are emitted successively by the corresponding light emitters 120, that is to say that no ultraviolet radiation Ru is emitted when another radiation Ru ultraviolet is emitted.

When the object 10 is illuminated by ultraviolet radiation Ru, the mark 15 emits visible radiation Rv, and is therefore visible by the human eye and by the photographic devices. The imager 60 then acquires an image Im corresponding to each ultraviolet radiation Ru when the ultraviolet radiation Ru considered is emitted.

During the transfer step 230, a transfer message Mt containing each image Im is generated by the second computer 80 and transferred, by radio frequency communication, to the mobile device 25. The transfer message Mt further comprises the identifier Id of the lighting device 30.

During the selection step 240, each image Im is displayed by the screen of the man-machine interface 55 to the user U. The user U then selects an image Im, preferably the image Im on which the mark 15 is the most visible. The selection step 240 comprises, for example, the enlargement, by the second computer 80, of a part of the image Im in order to make the image of the mark 15 more legible.

During the transmission step 250, the submission message Ms containing the image Im selected is sent by the first communication module 50 to the identification device 35. The submission message Ms contains the identifier Id.

Preferably, the submission message Ms also contains the geographical position P of the mobile device 25 at the time when the submission message Ms is generated.

During the authorization step 260, the identification device compares the identifier Id received at the transmission step 250 with each identifier Id of the list of identifiers Li.

If the identifier Id is identical to an identifier Id contained in the list of identifiers Li, the authorization step 260 is followed by the identification step 270. Otherwise, the authorization step 260 is followed by the refusal step 290.

During the identification step 270, the identification device 35 recognizes the mark 15 on the image Im received. It is understood by "recognizing" an action to identify, on the image Im, data associated with computer data contained in the second memory 160. Computer methods of pattern recognition are commonly used in many applications to identify geometric shapes or characters such as numbers or letters.

If the identification device 35 recognizes the mark 15, the identification device 35 generates, in the second memory 160, a computer representation Ri of the mark 15 received.

The identification device 35 then compares the received mark with each mark in the list of marks Lm. More specifically, the identification device 35 compares the computer representation Ri of the received mark with each computer representation Ri of the mark list Lm.

If the computer representation Ri of the received mark 15 is identical to a computer representation Ri contained in the mark list Lm, the communication step 280 is then implemented.

If the identification device 35 does not recognize the mark 15, or if the computer representation Ri of the mark 15 received is not identical to a computer representation Ri contained in the mark list Lm, the failure step 300 is then implementation.

During the communication step 280, the identification device 35 transmits to the mobile device an identification message Mi containing the description D of the object 10 bearing the mark 15. The description D is then displayed, at the destination of the user U, via the man-machine interface 55.

During the refusal step 290, the identification device 35 transmits to the mobile device a refusal message M. The rejection message Mr comprises, for example, a message, intended to be displayed by the human interface. machine 55, indicating that the lighting device 30 is not recognized by the identification device 35.

The geographical position P is also stored in the second memory 125. For example, the identification device 35 stores a marker indicating an unauthorized connection attempt. The marker comprises the identifier Id received, the geographical position P, and a date of receipt of the submission message Ms.

During the failure step 300, a failure message Me is transmitted, by the identification device 35, to the mobile device 25. The failure message Me comprises, for example, a message intended for be displayed by the man-machine interface 55, indicating that the object 10 could not be identified.

In order to use the identification system 20, the user U only needs to control, via the mobile device 25, the taking of an image lm of the object 10, and to select the image on which mark 15 appears. The identification system 20 is very easy to use.

In addition, the lighting device 30 and the mobile device 25 do not perform operations involving complex algorithms or a large calculation power, since the analysis of the images lm and the identification of the mark 15 is carried out by the identification device 35.

The lighting device 30 is therefore compatible with a wide variety of mobile devices 25, and it is often unnecessary for the user U to obtain a specific mobile device. Only the purchase of the lighting device 30 is necessary.

In addition, the system 20 is compatible with a large number of different mark formats, since only the identification device 35 needs to be programmed to recognize and identify the marks 15. It is therefore easy to make the system of identification 20 compatible with a new type of marks 15, for example a new type of matrix codes. In particular, such a modification does not involve modifying the lighting device 30 or the mobile device 25.

In addition, the identification system 20 is compatible with marks of very small areas, for example less than 0.8 square centimeters. Indeed, the use of a shape recognition step allows the identification system 20 to identify even a mark 15 of very small dimensions.

The identification system 20 is, furthermore, easily compatible with new types of marks 15 sensitive to different nominal wavelengths. It is sufficient for the user U to add a light emitter 120 adapted to the light emitters 120 already installed.

The identification system 20 is therefore more adaptable than the identification systems 20 of the state of the art.
