Method for managing sharing of location data between a source device of a user and a destination device of a third party, said method being implemented by a server which is remote from said source device of a user and from said destination device of a third party, said method comprising the following steps: - receiving, from the source device of the user, a first identifier of the source device of the user, a first identifier of the destination device of the third party, and an authorization message indicating whether the destination device of the third party is authorized to obtain location data from the source device of the user, - constructing or updating a lookup table associating the first identifier of the source device of the user with the first identifier of the destination device of the third party, - receiving location data from the source device of the user, - receiving, from a companion application dedicated to sharing location data and executed by said destination device of the third party, an identifier of the destination device of the third party, referred to as the second identifier of said destination device of the third party, said second identifier of said destination device of the third party being received during the creation of a user account with said server by a user of the companion application, - transmitting, in response to said receiving of said second identifier of the destination device of the third party, a message to said destination device of the third party, said message comprising an authentication code, - receiving, from the destination device of the third party, a request to transmit location data from the source device of the user, the receiving of the request using a token comprising the second identifier of the destination device of the third party and said authentication code, said request further comprising a second identifier of the source device of the user corresponding to the first identifier of the source device of the user, - verifying, using the authentication code, that said user of said destination device of the third party is authorized, - determining, using the second identifier of the source device of the user and the lookup table, whether the first identifier and second identifier of the destination device of the third party match, and - transmitting, to the destination device of the third party, the location data from the source device of the user, in response to the request, when the first identifier and second identifier of the destination device of the third party match. - receiving, from the source device of the user, a first identifier of the source device of the user, a first identifier of the destination device of the third party, and an authorization message indicating whether the destination device of the third party is authorized to obtain location data from the source device of the user, - constructing or updating a lookup table associating the first identifier of the source device of the user with the first identifier of the destination device of the third party, - receiving location data from the source device of the user, - receiving, from a companion application dedicated to sharing location data and executed by said destination device of the third party, an identifier of the destination device of the third party, referred to as the second identifier of said destination device of the third party, said second identifier of said destination device of the third party being received during the creation of a user account with said server by a user of the companion application, - transmitting, in response to said receiving of said second identifier of the destination device of the third party, a message to said destination device of the third party, said message comprising an authentication code, - receiving, from the destination device of the third party, a request to transmit location data from the source device of the user, the receiving of the request using a token comprising the second identifier of the destination device of the third party and said authentication code, said request further comprising a second identifier of the source device of the user corresponding to the first identifier of the source device of the user, - verifying, using the authentication code, that said user of said destination device of the third party is authorized, - determining, using the second identifier of the source device of the user and the lookup table, whether the first identifier and second identifier of the destination device of the third party match, and - transmitting, to the destination device of the third party, the location data from the source device of the user, in response to the request, when the first identifier and second identifier of the destination device of the third party match.
