Title: METHOD FOR AUTHENTICATING A USER VIA OPTICAL TRANSMISSION OF AN AUTHENTICATION TOKEN
Abstract: The present invention relates to a method and a system for authentication of a user for granting access to a service (110), the method comprising: receiving (S402), by a vehicle control unit (102) comprised in a vehicle (104), an authentication token based on a request for authentication for access to the service, the vehicle being in communicative connection with a remote server (108). A token sequence is sent by flashing with a light-emitting device (106) comprised in the vehicle (104), the token sequence is based on the authentication token. The token sequence is received by a light detecting device (112). The token is compared by the server with the authentication token. When the token sequence is determined to match the authentication token, access is granted (S408) to the service. The invention also relates to a vehicle implementing the method.

number: 5
text: The method according to any one of the preceding claims, wherein said light-detecting device (112) is a video camera, wherein said video camera acquires a video of the flashing light-emitting device for receiving said token sequence.
number: 6
text: The method according to any one of the preceding claims, wherein said light-emitting device comprises a plurality of light sources (202a-f), wherein each light source is flashable for sending said token sequence, each light source providing a light signal corresponding to a bit for each set of bits comprised in said token sequence.
number: 7
text: A system (100) for authentication of a user for granting access to a service (110), said user being associated with a portable electronic device comprising a light-detecting device (112), said system comprising:
number: 8
text: The system according to claim 7, wherein said light-detecting device is a video camera, wherein said video camera is configured to acquire a video of the flashing light-emitting device for receiving said token sequence.
number: 9
text: The system method according to any one of claim 7 or 8, wherein said server is configured to receive location information indicative of a present location for said portable electronic device, wherein when said location information is determined to match a location associated with the service, said server is configured to grant access to said service.
number: 10
text: The system method according to any one of claims 7 to 9, wherein said server is configured to receive location information indicative of a present location for said vehicle, wherein when said vehicle location information is determined to match a location associated with the service, granting access to said service.
number: 11
text: The system method according to any one of claims 7 to 10, wherein said server is configured to receive location information indicative of a present location for said vehicle, and to receive location information indicative of a present location for said portable electronic device, wherein when said vehicle location information is determined to match the portable electronic device location, granting access to said service.
number: 12
text: The system according to any one of claims 7 to 11, wherein said light-emitting device comprises at least one of: tail lights or head lights, or turn lights, or side repeaters, for said vehicle.
number: 13
text: The system according to any one of claims 7 to 12, wherein said portable electronic device is a mobile phone.
number: 14
text: A vehicle comprising a light-emitting device and a control unit, wherein said control unit is communicatively connected with a remote server,
wherein said server is configured to receive an authentication request from a service, and to provide an authentication token to said vehicle control unit,
wherein said vehicle control unit is configured to control said light-emitting device to flash for emitting a token sequence receivable by a light-detecting device of a portable electronic device,
wherein said server is configured to receive said token sequence from said portable electronic device, and to compare said token sequence with said authentication token, and, when said token sequence is determined to match said authentication token, grant access to said service.
