## Abstract

The invention relates to a method for identifying and authenticating a user profile, allowing the use of services connected to a multimedia system on-board a motor vehicle (2), the multimedia system comprising a memory (221) comprising a user profile for a portable device (5), the vehicle comprising a first device for communicating with a remote server (3), the remote server comprising a memory (222) and a second system for communicating with the portable device, the portable device (5) comprising a memory, the method comprising a step of detecting the presence of a portable device (5), if a portable device (5) is detected, the method comprises a step of receiving authentication information of the user, a step of transmitting the authentication information to the remote server, a step of verifying the authentication information, and a step of the multimedia system receiving a confirmation of the use of the user profile if the authentication information is compliant.

## Claims

### Claim 1

A method for identifying and authenticating a user profile, making it possible to use connected services on a multimedia system on board a motor vehicle, the multimedia system comprising an on-board memory in which a user profile for a portable device is stored, the vehicle comprising a first device for communicating with a remote server, the remote server comprising a storage memory and a second system for communicating with the portable device, the portable device comprising a storage memory, wherein the identification and authentication method comprises:
a step of detection by the multimedia system of a presence of a portable device in the vehicle;
when a portable device is detected, the method comprises:
a step of reception by the multimedia system of the vehicle of authentication information of the user of the detected device stored on the detected portable device,
a step of sending by the multimedia system the authentication information of the user of the detected portable device to the remote server,
a step of verification, on the remote server, of the authentication information of the user of the detected portable device,
when the user authentication information matches the identification information of a user recorded in the storage memory of the remote server and previously received by the remote server via the second communication system, then the method comprises:
a step of reception by the multimedia system of a confirmation of the use of the user profile stored on the multimedia device.

### Claim 2 (depends on 1)

The method for identifying and authenticating a user profile according to claim 1, wherein the on-board memory of the multimedia system comprises a plurality of portable device user profiles, and when, during the step of detection by the multimedia system of the presence of a portable device in the vehicle, the multimedia system detects several portable devices, the authentication information of the step of sending the authentication information of the user of the detected portable device to the remote server corresponds to the user for which the use of the profile was validated most recently on the multimedia system.

### Claim 3 (depends on 1)

The method for identifying and authenticating a user profile according to claim 1, wherein when, during the step of detection by the multimedia system of the presence of a portable device in the vehicle, no portable device is detected by the multimedia system, the last user profile to be used on the multimedia system will be used.

### Claim 4 (depends on 1)

A system for identifying and authenticating a user profile, making it possible to use connected services on a multimedia system on board a motor vehicle, wherein the system comprises means for implementing the identification and authentication steps according to claim 1.

### Claim 5 (depends on 1)

A computer system comprising one or more processors, a non-transitory computer readable medium, and a computer program stored on said non-transitory computer readable medium, the computer program comprising instructions, which when executed by said one or more processors implement the method for identifying and authenticating a user profile according to claim 1.
