FIELD OF THE INVENTION The invention relates to a system for certifying a screening of a gaseous substance present in the air exhaled by an individual, the system comprising a sensor connected to a portable terminal. The invention relates in particular to the fact that the camera of the terminal takes an image of the individual doing the test in order to authenticate it by facial recognition. 2. Prior Art
    Nowadays alcoholism becomes a real societal problem. In France, there are 45,000 deaths each year related to excessive alcohol consumption. This is the second leading cause of preventable death in our country. Drugs such as cannabis and heroin are also the cause of many deaths from over-consumption. The damage that these substances cause sometimes goes unnoticed, and it is only with time that the effects are gradually felt, at that moment it is often too late. The so-called "psychotropic" substances act on the state of the central nervous system by modifying certain brain biochemical and physiological processes. The functions of the brain are altered by modifying the perception, the sensations, the mood, and in a general way the consciousness and the behavior of the one who consumes it, which is why they are harmful.
    The society condemns the use of these psychotropic substances and especially when they are taken before driving. One of the leading causes of road fatalities is alcoholism. In addition to the penalties for driving with a blood alcohol level higher than the legislation in force, the effects of drunk driving are known: narrowing of the visual field, reduced alertness and fatigue resistance, decreased reflexes, impaired ability to appreciate distances, increased sensitivity to glare or overconfidence. To detect the absorption of such substances, the authorities have developed means of detecting the blood alcohol level or the absorption of certain drugs. But the frequency of controls is low and makes little dissuasive these measures. Drunk driving can also be fought by developing the practice of self-screening. To do this, the authorities recently forced owners to have at least one breathalyzer in their vehicle. The purpose of a breathalyzer is to be able to indicate the alcohol content in the alveolar air exhaled in the breath of its user. Note that this rate is directly correlated to blood alcohol level. Recently released electronic breathalyzer models are connectable to a smartphone ("smartphone") and measure the rate of psychotropic substances exhaled by an individual. The measurement is sent to the smart phone for display purposes. The user of the ordiphone can thus self-test and decide knowingly to take the wheel or not. Nevertheless, if the individual does not take the test, or if the test is done but his judgment is too impaired, the individual can take the wheel and put himself in danger. If an individual is in a state of health not compatible with driving, then it must be prevented by all means to drive a vehicle. This attitude must be taken regardless of the activity of this individual, not just driving. The test can also be done by airplane pilots before taking off. The test can also be an incentive to encourage withdrawal. The ethylotest can be used by a patient for therapeutic purposes to ensure daily monitoring of his blood alcohol level and thus encourage him to stop drinking.
    Patent application US7934577 describes a control mechanism within a vehicle that requires the driver to self-test by a breathalyzer before driving. If the result of the test is positive (psychotropic substances have been detected and in proportions beyond a threshold) or if the test is not performed, then a control device prevents the engine from starting. If the result is negative, then the control device allows the ignition of the engine. This document provides for the vehicle to include one or more cameras making it possible to identify the driver. The cameras and the breathalyser are connected to the control device of the vehicle. This provision, however, has the disadvantage that it is possible to cheat by blowing the driver in an unconnected breathalyzer and another individual in the ethylotest that is actually connected to the vehicle control device. There is therefore a real need for a system of certification of the authenticity of a test for a gaseous substance applied to an identified individual.
    Document US 6,956,848 describes a system for verifying the identity of an individual, in that the image taken during the screening is compared with an image already taken. This only works in the case of an anti-start alcohol breath test, when you know the limits of this device. In addition, it is extremely difficult to provide a photo taking system in the case of an anti-start alcohol test. 3. Objectives of the invention
    The present invention provides a solution that does not have the drawbacks of the prior art. The proposed solution ensures that the measurement of the level of psychotropic substances is associated with an individual whose identity is well recognized. This invention allows in particular to prohibit this individual to perform an activity at risk for him or for people nearby. 4. Presentation of the invention
    The present invention provides a certification system for a screening of a gaseous substance present in the air exhaled by an individual, said system comprises a sensor detecting said gaseous substance in the exhaled air. Said sensor comprises a unit for collecting and analyzing a sample of air exhaled by said individual, able to provide a measurement of the amount of gaseous substance per unit volume. Said system further comprises a portable terminal equipped with a means of communication with the sensor for at least receiving the measurement. The portable terminal is provided with a camera intended to take an image of the individual blowing in said sensor to perform a screening, and an authentication module of the individual and the sensor used for this sample of exhaled air by analyzing the image data by facial recognition for the individual and analyzing a graphic marker affixed to the sensor. The terminal produces an information set comprising a datum representative of the quantity of gaseous substance measured in the sample and an authenticated identification datum of the individual having exhaled this sample.
    In this way, the system can both authenticate the identity of the person performing the test, authenticate the sensor that is used for the test, and associate the result of the value of the screening to that person. These data can be used by any control system to allow the test taker to perform a certain activity or to prohibit it if it can endanger himself or a group of individuals.
    According to a first embodiment, the system comprises a control device in communication with the terminal, said device controlling the operation of a vehicle and allowing it to start when the individual identified by the received data is authorized to drive the vehicle and when the transmitted measurement indicates that the gaseous substance is not present or below a certain threshold. In this way, the vehicle can only start when the screening has been negative.
    According to another embodiment, the system comprises a sound transmission means integrated in a vehicle, such as a horn, the emission means is activated when the transmitted measurement indicates that the gaseous substance is present beyond a certain threshold. In this way, a sound signal is emitted warning the individual and his entourage that the screening was positive.
    According to another embodiment, the system comprises a remote device communicating by radio with the portable terminal, the remote device transmitting to the mobile terminal a signal triggering the appearance of a menu displayed on a screen of the portable terminal and requesting screening, the mobile terminal transmitting to this remote device by the mobile network information representative of the measurement and the authenticated identification data of the individual. In this way, a device centralizing data is constantly updated on the status of the screenings practiced on the members of an organization.
    According to another embodiment, the remote device triggers an alarm if no screening having resulted in a negative result has taken place correctly during a determined period. In this way, the tracking of an individual who has not been detected for some time is facilitated.
    According to another embodiment, the portable terminal has a geolocation means for the remote device to know its position, the remote device transmitting to the portable terminal the signal triggering the appearance of a menu as a result an immobilization of the terminal during a minimum period. In this way, if a driver makes a stop to eat for example, the system detects it and asks him to carry out a screening.
    According to another embodiment, the portable terminal detects the start-up by the individual of a device for use, the start-up triggering the appearance of the menu asking this individual to perform a screening. In this way, it is possible to request a screening each time a user of a machine turns it on.
    According to another embodiment, said sensor comprises an anemometer detecting the air flow resulting from an exhalation, the detection of an air flow resulting from an exhalation triggering the taking of at least one image. In this way, the image is synchronized with the exhalation of the individual which limits cheating.
    According to another embodiment, the graphic marker of the sensor is a visible light on the side opposite to that of a mouthpiece in which the individual blows during a screening, the light beam emitted by this indicator has characteristics identifying said sensor. In this way, the authentication of the sensor by the terminal is facilitated.
    According to another embodiment, at least one characteristic of the light beam emitted by the indicator light visible on the face opposite to that of a mouthpiece is provided by the portable terminal via the communication means 9. In this way, the Sensor authentication by the terminal is enhanced, making cheating almost impossible by using another sensor.
    According to another embodiment, the graphic marker is a QR Code or A_Barre code affixed to the opposite side to that of a mouthpiece. In this way, the authentication of the sensor by the terminal is facilitated and requires less computing power.
    In another embodiment, the terminal initiates communication with the sensor to ensure that only one sensor is connected. In this way, the fraud of using at least two sensors is almost impossible.
    In another aspect, the invention relates to a method of certifying a screening of a gaseous substance present in the exhaled air by an individual using a sensor detecting said gaseous substance in the exhaled air. This method comprises the following steps: exhalation by said individual in said sensor to provide a measure of the amount of gaseous substance per unit volume, taking at least one image of the individual blowing in said sensor to perform a screening with the camera (4) of a portable terminal (2) connected to said sensor (5), - authentication of the individual and the sensor used for this sample of exhaled air by analyzing the image data by facial recognition for the individual and by analyzing a graphic marker affixed to the sensor, - production by the terminal (2) of a set of information comprising a datum representative of the quantity of gaseous substance measured in the sample and a authenticated identification data of the individual who exhaled this sample.

DESCRIPTION OF AN EMBODIMENT OF THE INVENTION 6.1 GENERAL PRINCIPLE The invention relates to a system for certifying a screening of a gaseous substance present in the air exhaled by an individual. The system comprises a sensor detecting said gaseous substance in the exhaled air, said sensor comprising a unit for collecting and analyzing a sample of air exhaled by said individual, able to provide a measurement of the quantity of gaseous substance by unit of volume. The system further comprises a portable terminal having a means of communication with the sensor for at least receiving the measurement. The portable terminal is provided with a camera intended to take an image of the individual blowing in said sensor to perform a screening, and an authentication module of the individual and the sensor used for this sample of exhaled air by analyzing the image data by facial recognition for the individual and analyzing a graphic marker affixed to the sensor. The terminal produces a set of information comprising a datum representative of the quantity of gaseous substance measured in the sample and an authenticated identification datum of this individual having exhaled this sample. In this way, the system can both authenticate the identity of the person performing the test, authenticate the sensor that is used for the test, and associate the result of the value of the screening to that person. 6.2 Particular embodiment
    Fig. 1 represents a certification system for a screening of a gaseous substance according to an exemplary embodiment. The system 1 shown comprises a portable terminal 2 provided with a means of communication with a network, such as a mobile telephone network and a user interface 3 such as a screen and a keyboard. This interface may alternatively comprise a touch screen, or a voice recognition unit for receiving commands and to issue information to a user. The terminal 2 comprises a software module for downloading applications from the telephony network and a module for executing downloaded applications. The terminal 2 is also equipped with a camera 4 capable of taking photographs or videos, in particular of the user who can hold it at the end of the arm. This user may be the driver or any other person, such as a person of full age accompanying a minor during an accompanied driving. The system also comprises a sensor 5 comprising a unit for collecting and analyzing a sample of air exhaled by said individual, able to provide a measurement of the amount of gaseous substance per unit volume. This gaseous substance is preferably of the psychotropic type and covers in particular alcohol, cannabis, heroin. The sensor 5 may have a display means 6. The sensor 5 comprises a tip 7 allowing its user to exhale a charged or unloaded breath of said gaseous substance in a conduit 8 where it is analyzed, the exhaled air escaping at one end of the duct 8 opposite the tip 7. The sensor 5 is in communication with the portable terminal 2 by a computer link 9 wired or wireless (Wifi type for example).
    By connecting to a remote site, the terminal 2 downloads the APLY application for authenticating a screening. Once downloaded, the APLY application activates the camera 4 and the sensor 5 and informs the user that the test is ready to be performed. According to an improvement, the terminal 2 initiates a communication with the sensor 5 so as to ensure that only one sensor is connected. The user directs the lens of the camera towards him so that part of his face appears on the captured images. Ideally, at least one image is taken when the user is blowing into the tip 7, but this is not a necessity, the images can be taken shortly before or after the test. The sensor currently in use requires a warm-up time that can be used to take a photograph and identify the person. At least a portion of the user's face and the sensor 5 are visible on the captured image. According to the invention, the sensor 5 used has a graphic marker 10 making it possible to identify it among any other sensor. This marker is for example an A-bar code, or a QR-code, or any graphic symbol appearing on the side of the sensor opposite to that of the tip. This marker can also be a luminous element such as an LED or a light which at least one light characteristic identifies the sensor. For example, the diode is controlled by a PWM generator whose frequency and the duty cycle are particular to this sensor, and can not be known from another sensor. These light signals are picked up and analyzed by the camera of the terminal. The frequency and the duty cycle are also transmitted by the link 9 so as to be compared. Advantageously, the characteristics of the light beam identifying said sensor are provided by the portable terminal 2. In this way, only the sensor in communication with the terminal can know them and we can ensure that only one sensor is connected to this terminal . The APLY application analyzes image data, or images taken to look for a face, and then, to identify the user by facial recognition. The APLY application also searches for the presence of the graphic marker 10, and in case of detection, the analysis to extract the identifier. The image analysis can be performed during a preheating step of the sensor and / or at the time of measurement. In all cases, taking pictures and measuring the sensor are done at very close times to ensure that the person photographed is the one who breathes in the breathalyzer. Advantageously, the screen of the terminal 2 displays indications to help the user to perform the screening. These indications are for example: "Center your face", "Put the tip of the sensor in your mouth", "Keep your face in the center of the image and still", "Hold the sensor by its lower part", " Inhale deeply and then blow. " Thank you ! The test is finished. "
    The terminal warns the user when the sensor is operational by a light signal (message displayed on the screen 6, lighting of the LED diode, lightning flash, ...) or sound, or by vibration. The appearance of this light signal and / or sound triggers the taking of at least one image with the camera 4, during this time the sensor 5 analyzes the breath exhaled by the user and passing through the conduit 8 to determine the rate in psychotropic substances. If the image taken does not allow the identification of the user and the sensor, a message appears on the screen 3 asking to repeat the test. Here are the most frequent reasons for the failure of a test: - the user is not recognized, - the sensor is not recognized, - the face leaves the field of the camera, - other faces are present in the image, - the duration of the process is too long, - the quality of the image taken is insufficient (brightness, contrast, focus) - the quality of the reference image is insufficient. The APLY application receives from the sensor 5 via the link 9, the data representative of the measurement of the quantity of gaseous substance per unit of volume, and the identifier of the sensor. The application can then compare the identifier received from that extracted from the image of the sensor and compare them. If the identifiers are equal, then the sensor is authenticated otherwise an error message is displayed. The application identifies the user by facial recognition and once these checks are made, associates the measurement with the identity of the user who did the test. In this way, cheating on the user performing the test is virtually impossible to achieve.
    Such a system can be used by many applications. The present invention provides for integrating this system into an immobilizer mechanism of a vehicle, and in a method of controlling the state of the members of an organization. 6.3 Application in an immobilizer mechanism
    Fig. 2 illustrates an immobilizer mechanism incorporating a certification system of a screening. This mechanism is present in a vehicle 11 which comprises an onboard computer 12 communicating in particular with the electronic ignition of the engine with the fuse table of the vehicle, or a wave jammer preventing the propagation of the wave emitted by a key without contact. According to an alternative embodiment, the mechanism controls the horn of the vehicle and triggers an effect similar to that of a flight when the screening is positive. With this communication, the on-board computer 12 can prohibit the starting of the engine when the driver 13 uses his key and when certain conditions on the state of health of the driver are not respected, this state being provided by the system 1 screening certification previously described. The onboard computer has a communication module with the portable terminal 2 of the driver, this communication is preferably made by short-range radio link (using the "Bluetooth", for example), it can also s' perform a wired connection (via a "USB" port for example).
    One embodiment of a method for prohibiting the starting of a vehicle is explained by the flow chart of FIG. 3 given as an example. This flowchart shows the steps of an application using the system 1. In step 3.1, the driver enters the vehicle and requests a start with the ignition key. The computer receives the start command in the form of a signal and informs the driver of the need to test for psychotropic substances (step 3.2). This information can be done by a display on a screen or by voice synthesis. The on-board computer then asks the driver to launch the APLY application on his terminal. In step 3.3, the on-board computer enters into communication with the portable terminal 2 and waits for the data resulting from the test. The portable terminal activates the sensor 5 and warns the driver when the sensor is operational (step 3.4). In order to prepare the test, the terminal informs using its screen 3 of the conditions for setting up the test. These conditions consist in that the driver's camera is placed facing him, possibly by hooking it to the central mirror as shown in FIG. 3, so that the image data taken at this time includes both the driver's face and the sensor side where the graphic marker is located. In step 3.5, the terminal receives the measurement data from the sensor and analyzes the image (s) taken by the camera. The APLY app performs a facial recognition task to determine the identity of the person in the photo. This technology is known per se and can provide an identity with maximum certainty. The APLY application also executes a search program of the graphic marker present on the sensor and decoding of this graphic marker in order to extract the identifier associated with the sensor. The sensor 5 also transmits to the terminal 2 the result of the measurement and its identifier by its link 9. The terminal then compares the identifier received from the sensor of the sensor and the decoded identifier of the graphic marker (step 3.6). If the identifiers are not identical, then one may suspect cheating and the terminal 2 transmits to the computer 12 a signal representative of a failure of the measurement. By receiving this signal, the computer will not allow the engine to start (step 3.7). If on the other hand, the identities are respected then the breath analyzed is that of the person who is present in front of the camera 4 and who holds the sensor 5 in hand. In this case, in step 3.8, the APLY application compares the representative data. the amount of gaseous substance per unit volume with a threshold value. The threshold for blood alcohol is for example 0.5 grams per liter of blood. If the threshold is exceeded, the terminal 2 sends to the computer board 12 a signal indicating that the identity of the driver is verified but is not in a state to drive. A "change of driver" type message may be reproduced (step 3.9). If, on the other hand, the blood alcohol threshold is not exceeded and if no drug is detected, the computer authorizes the engine to start (step 3.10). The application thus described makes it possible to ensure with a high level of safety that the driver has carried out the test. According to a technique known per se, the sensor 5 has a micro-anemometer 14 integrated in the duct 8 which controls in particular that the flow of exhaled air and its volume is sufficient, in fact only the alveolar air is charged with alcohol and you have to blow a certain volume without stopping to exhale it. According to an optional improvement, as soon as the microanemometer detects the presence of a breath, the sensor transmits to the terminal 2 a start of measurement signal which triggers the taking of at least a first image. When the micro-anemometer detects the end of the breath, the measurement is completed and the measurement value of the rate of psychotropic substance is transmitted to the terminal. 6.4 Application in a screening mechanism of the screening status of members of an organization
    The certification system of a gaseous substance screening can also be used to monitor the screening status of members of an organization, and this with a high level of security. The term "organization" describes any group of individuals responsible for carrying out a certain work requiring a good level of health and under the responsibility of an authority. An organization is for example a transport company where drivers carrying passengers make journeys. It can also include workers in a factory, tile washers, masons, etc ... in general any occupation for which an employee must be in full possession of his means.
    Fig. 4 illustrates such an application in the field of transport, for example coaches carrying passengers. During its journey, bus 20 crosses geographical areas covered by telephone networks represented by fixed stations 21, belonging to a mobile phone operator type 3G / 4G for example. The driver of the bus is equipped with the system 1 described above. The portable terminal 2 communicates with the various fixed stations 21 and has a geolocation means. This means can be the telephone network itself by triangulation analysis of the return times of communications with several fixed bases. This means can also be a GPS module (Global Positioning System) integrated in the terminal. In all cases, the location of the terminal, and consequently that of the bus driver, is transmitted via the telephone network to a remote server, called "management of the members of the organization", or server "GMO" 22 .
    Fig. 5 illustrates the main components of a GMO server 22. According to this exemplary embodiment, the GMO server 22 comprises an ALU central unit 23 connected to an executable program memory PM 24, an HD hard disk 25 containing a database for the non-volatile data storage. The program memory includes a GMO application for managing the members of the organization and for knowing at least the latest screenings that have been performed on them. The server 22 also contains an I / O interface 26 for communication with the telephone network. The messages received by the I / O interface make it possible to receive data on the screening carried out on the various drivers making trips. It is not excluded that the connection means differ according to the type of device in communication, so the optimization server 23 can communicate with the telephones through a wireless network (3G / 4G mobile telephony) or by a cable via any digital network (Internet for example).
    After having detailed the main elements of this application, we will now explain how they cooperate.
    One embodiment of a limb health management application is explained by the flow chart of FIG. 6 which illustrates a preferred embodiment. The flow chart example shows the steps of an exemplary implementation of the method according to the invention.
    During a preliminary step 6.1, the server 23 initializes in its memory 25 a table comprising lines corresponding to each member of the organization. Each line of the table contains the following information: Identity (first and last name) of the member and telephone number, biometric data identifying the member's face, date and time of the last test, state of the last test. At a given moment a need for personnel appears and a step of searching for at least one member able to carry out a certain work is launched. The GMO app then calls a sub-list of members and asks them to perform the screening test (step 6.2). The test is carried out using the system described in paragraph 6.2. As soon as the first results arrive at the server, they are stored in the memory 25 (step 6.3). Advantageously, the location of the place of screening is also recorded. In step 6 .4, at least one member is selected for the job to be performed. These selected members must of course have made a negative screening. The selected members are then contacted to give them instructions to follow in order to complete the requested work.
    According to an improvement, during the performance of the work, the member is contacted by his portable terminal 2 to perform a new screening (step 6.5). The triggers of these new screenings can be performed at regular intervals of time, every 3 hours, for example. According to one variant, the trigger occurs randomly over time, for example in a time range between one hour and 6 hours from the previous test.
    If a new test can not be done, there is a doubt about the screening status of this member, so the server can trigger an alarm in order to replace this member by another, the other having previously been screened negative.
    According to an improvement, if the screening is positive, then a message is sent to at least one third person whose identity is stored in the server 23. The message can be transmitted by any means: SMS, email, voice call by phone, ... This person may be a parent (in the context of family monitoring, for example), either to a line manager or a safety officer (in the context of work and remote screening), or to a medical advisor or a health professional.
    According to a development that applies primarily to an organization in the field of transportation, the GMO server tracks in real time the movement of members and determines whether they are mobile or fixed. The triggering of a new screening is done when the member does not move in his vehicle, or in other words if his speed of movement is less than 5 km hour for example. Beyond this value, we can consider that he is driving and that it is not the moment to disturb him. According to another improvement, the test can be performed when the GMO server detects an immobilization for at least a certain time, then a displacement less than a certain speed (typically 5 Km / h, which can mean that after a stop, the driver regains his vehicle on foot). We can assume that he had a lunch break and that it is time to check that he has not consumed alcohol.
    According to an alternative embodiment, the terminal 2 receives short-range radio signals from local transmitters, these signals triggering the screening (step 6.6). This variant occurs for example when activating the ignition key of a vehicle, or the start of the machine on which a worker works. This variant can also intervene when surveillance cameras detect the unusual behavior of an employee. According to this variant, once the screening is carried out, the terminal 2 transmits the results to the GMO server for the purpose of recording in the memory 25. This variant is perfectly combinable with the fact that the server also requests to carry out screenings. In this case, the server GMO stores in the memory 25 the equipment that triggered the screening: either a local device or the server. 6.5 Application to manage medical records
    The certification system for a gaseous substance screening can also be used to update delocalized medical data. Patients are prevented from performing tests at certain times and the values thus measured are transmitted by the telephone network and recorded in a remote server. Depending on the patient, screening requests are made at random times during a given period, or at fixed times, or during the patient's "craving" periods (ie, at times where he has an irrepressible desire to drink), the server is searchable by health professionals who can see the rate of psychotropic substances exhaled by a patient, and see the evolution over time. This evolution is particularly useful during weaning, especially to help a person to no longer be dependent on alcohol. Access to the server data is secure so that only healthcare professionals and / or the patient himself can read the recorded data. Authorizing the patient to access the data is a help because it allows him to see that his efforts are producing results. Depending on the value of the detected rate, messages are sent to the people, either congratulatory messages if the values are low, or messages of encouragement, or messages urging him to contact a health professional. The invention is not limited to the embodiments that have just been described. In particular, the system is usable for any human activity where it is necessary to ensure that the measurement of the rate of psychotropic substances associated with an individual is well below a determined threshold.
