Description

TECHNICAL FIELD

[0001] The present invention relates generally to a method for identifying and authenticating a user profile to use a service loaded on a motor vehicle. BACKGROUND

[0002] All types of vehicles, such as private, commercial, utility, agricultural, collective or military vehicles, generally comprise an on-board multimedia system allowing access to on-board services, such as management of comfort parameters (cabin air conditioning) or radio frequency reception.

[0003] These on-board multimedia systems are now able to allow access to online services via a remote connection, in particular a wireless connection of 3G, 4G, 5G type or Wi-Fi, Sigfox, ZigBee or LORA. These online services can provide access to content, such as audio, video or audiovisual content, but also updates, maps or navigation information.

[0004] Such a multimedia system is known, for example, from document WO2014 / 035434.

[0005] However, such online services can require login information in order to establish a backup of content and / or settings or subscriptions or payment systems. This connection information can therefore be associated with personal and / or banking information of the user, and it is not desirable to share this information with other users of the vehicle.

[0006] Document WO201435434 describes a method for providing a service in a unit of a vehicle, the method comprising receiving, by a server, a request from a remote peripheral device (mobile device) of an authenticated user, identifying, by the server, a remote vehicle unit associated with the request, and providing, by the server, a service or information to the vehicle unit based on preferences of the authenticated user in response to the request.

[0007] However, this authentication is not associated with a profile identifying the user in the vehicle. SUMMARY

[0008] The purpose of the invention is to provide an identification and authentication method that can take into account various scenarios in which there is one or more or no portable device registered in the vehicle.

[0009] To this end, a first aspect of the application relates to a method for identifying and authenticating a user profile, said method enabling the use of connected services on a multimedia system loaded on a motor vehicle, said multimedia system comprising an on-board memory in which a user profile for a portable device is stored, said vehicle comprising a first communication device for communicating with a remote server, said remote server comprising a storage memory and a second communication system for communicating with said portable device, said portable device comprising a storage memory, characterized in that said identification and authentication method comprises a detection step of detecting the presence of a portable device in said vehicle by said multimedia system; if a portable device is detected, said method comprises a reception step of receiving, by said multimedia system of the vehicle, user authentication information of said detected portable device stored on said detected portable device; a transmission step of transmitting, by said multimedia system, user authentication information of said detected portable device to said remote server; a verification step of verifying, on said remote server, user authentication information of said detected portable device; if said user authentication information matches user identification information recorded in the storage memory of said remote server and previously received by said remote server via said second communication system, then said method comprises a reception step of receiving, by said multimedia system, a use validation of a user profile stored on said multimedia device.

[0010] Thus, it can be understood that the method according to the application identifies and authenticates the user only by detecting said portable device.

[0011] According to another embodiment, the on-board memory of said multimedia system comprises a plurality of user profiles of portable devices, and if, during the detection step of detecting the presence of a portable device in said vehicle by said multimedia system, said multimedia system detects a plurality of portable devices, the authentication information transmitted to said remote server in the transmission step of transmitting user authentication information of said detected portable device corresponds to the user whose profile was last validated on said multimedia system.

[0012] According to another embodiment, if, during the detection step of detecting the presence of a portable device in said vehicle by said multimedia system, no portable device is detected by said multimedia system, the user profile last used on said multimedia system is used.

[0013] A second aspect of the application relates to a system for identifying and authenticating a user profile, said system enabling the use of connected services on a multimedia system loaded on a motor vehicle, characterized in that it comprises means for implementing the steps of the identification and authentication method according to the first aspect of the application.

[0014] A third aspect of the application relates to a computer program comprising instructions for implementing the identification and authentication method according to the first aspect of the application when said instructions are executed on one or more processors. BRIEF DESCRIPTION OF DRAWINGS

[0017] - Figure 2 A schematic view of the interaction between a user, driver or passenger of a motor vehicle and said motor vehicle according to the method of the application is shown in a first embodiment of the method according to the application;

[0018] - Figure 3 A schematic view of the interaction between a user, driver or passenger of a motor vehicle and said motor vehicle according to the method of the application is shown in a second embodiment of the method according to the application. DETAILED DESCRIPTION

[0019] Figure 1 A user environment of a motor vehicle 2 is schematically shown, which can be a driver or passenger of the vehicle 2 and the vehicle 2. The user can have an electronic device 5, for example a smartphone, which will allow authentication for online services, as described below.

[0020] Optionally, the vehicle 2 is connected to a remote extension server 3 via a communication network 100. The communication network 100 here comprises a mobile telephone network, through which the vehicle 2 is able to connect to a network, for example the Internet, and access online services and / or multimedia applications, for example online services and / or applications dedicated to motor vehicle drivers and / or passengers.

[0021] The vehicle 2 comprises an on-board multimedia system provided with, inter alia, a return component comprising at least one display 21 arranged for displaying remote content, i.e. remote applications, catalogues or services, for the user of the vehicle. The vehicle 2 further comprises a storage component in the form of a local memory unit 221 to store information, a remote detection component, a remote communication component, for example a communication module 23, to allow communication with the electronic device 5 and / or with the remote extension server 3 via the communication network 100, and an authentication module 24 usable in cooperation with the communication module 23 and the memory unit 221 to authenticate the electronic device 5. Optionally, said detection component and said remote connection component can be two distinct modules.

[0022] Finally, a human-machine interface, not illustrated, allows the interaction with the user via a touch layer and / or buttons and a keyboard of the display 21. Moreover, the portable electronic device 5 can constitute at least part of said human-machine interface.

[0023] The extension server 3 is used to extend some capabilities and / or functions of the vehicle 2, for example storage capabilities. In particular, the extension server 3 can comprise a remote memory unit 222 arranged for storing vehicle configuration data, so that these configuration data are accessible from another vehicle. The system comprising the local memory unit 221 of said vehicle and comprising said remote memory unit is called the extended memory 22 of said vehicle.

[0024] During a previous configuration, for example during a parameter setting step, one or more users of the vehicle 2 create and configure respectively at least one user profile by using said human-machine interface, for example the display 21 of the vehicle 2. All the user profiles thus configured by the users are stored in the extended memory 22 of the vehicle 2, in particular in the local memory unit 221.

[0025] It is also possible to consider storing the created user profiles in the remote memory unit 222 of the remote extension server 3. In this case, the memory units of the vehicle 2 and of the extension server 3 can be synchronized.

[0026] The user profile comprises an identifier represented by a name and / or an icon or an image, said identifier being associated with a portable electronic device as identified by a unique identification number. Moreover, the user profile can comprise a set of personal data related to the user, in particular configuration data associated with the use of the vehicle 2 and specific to said user, for example a list of presets of the user's favorite radio stations, adjustment data for the vehicle seat of said user, adjustment data for one or more rearview mirrors of said user, etc.

[0027] Moreover, the user personal data can comprise a list of online services, for example comprising remote applications, directories or contents to be displayed or played by the multimedia system loaded on the vehicle 2. The remote applications are for example applications able to monitor or predict vehicle maintenance, financial services, or map, navigation or tourism guide services, or services providing enhanced navigation with information specific to the user's interests. The contents can be music or videos, newsletters or images. The directories can be lists or services providing applications for purchasing or subscribing to remote contents. In particular, it is possible to provide for each user to store information associated with the identity of said user, in particular connection information, for example a password or a payment authorization for a given remote application, directory or service.

[0028] It is noted that an online service can generally be displayed in two forms: a public mode, i.e. a version of the online service accessible by any user; and a private mode, i.e. when the user has chosen an identifier and entered connection information, such as an access code or banking details, in order to, for example, carry out a purchase and for which payment is made.

[0029] Similarly, during another previous configuration, the user saves user authentication information on the portable device 5, for example via a dedicated application stored on the portable device. According to the application, his authentication information is also stored on the remote server. This authentication information is used to validate the use of the services associated with the user.

[0030] According to a first step E0 of the method according to the application, the multimedia system of the vehicle 2 detects the presence of a portable device 5 in the vehicle 2. This detection is triggered, for example, when the vehicle 2 is unlocked or when the ignition of the vehicle is started. If a portable device 5 is detected and corresponds to a previously saved user profile, the user profile is pre-selected on the multimedia system of the vehicle. If the user selects this pre-selected user profile on the multimedia system, the portable device 5 transmits E1 the user authentication information stored on the portable device to the multimedia system of the vehicle 2. Upon receipt of this authentication information, the multimedia system sends an authentication request to the remote server from the user of the detected portable device 5. This authentication request includes the authentication information. This authentication information received by the server is compared with the authentication information stored on the remote server 222. If the received authentication information does indeed match the authentication information already stored, the remote server 22 transmits E2 a request to the multimedia system of the vehicle to validate the use of the user profile selected by the user. The receipt of the request by the multimedia system of the vehicle to validate the use of the selected user profile triggers the activation E3 of the services associated with the user profile and the activation of the configuration data associated with the use of the vehicle.

[0031] According to an optional embodiment, if several previously registered portable devices 5 are detected by the multimedia system during the detection step, the user profile pre-selected on the multimedia system will correspond to the last one validated on the multimedia system.

[0032] According to another optional embodiment, if no previously registered portable device 5 is detected by the multimedia system during the detection step, the user profile pre-selected on the multimedia system will correspond to the last one validated on the multimedia system. However, if this user profile is selected by the user, the activation of the services associated with this profile will only be triggered in a mode in which the personal data of the user cannot be used, for example in public mode.

[0033] If the user decides not to select a pre-selected user profile on the multimedia system at the end of the detection phase, he has several possible options. According to a first option, the user can select another user profile E4 from the list of user profiles already saved on the multimedia system. In this case, the activation of the services associated with this profile will only be triggered in a mode in which the user's personal data cannot be used, for example in public mode.

[0034] According to a second option, the user can not select E5 any of the user profiles offered in the list of user profiles already registered on the multimedia system. In this case, a default pre-selected user profile will be automatically triggered by the multimedia system in a mode in which the user's personal data cannot be used, i.e. in public mode when the vehicle 2 is in use, i.e. when the ignition is on. If the vehicle 2 stops, the multimedia system of the vehicle 2 can be automatically turned off E6 after a determined time length.

[0035] It should be understood that various modifications and / or improvements to the various embodiments of the application described in the present specification can be made to those skilled in the art without departing from the scope of the application.
