using the at least one subscription key to authenticate the mobile device as having obtained the subscription;
augmenting, by the vehicle ECU, the information application with the subset of the vehicle sensor data accessed based on the at least one vehicle sensor key;
installing, in the memory of the vehicle ECU, at least one region key for a geographic region;
in response to the request for the subscription, transmitting, by the vehicle subscription server, the at least one region key;
outputting to the information application, by the vehicle ECU, the subset of the vehicle sensor data based on the at least one subscription key and the at least one region key;
installing, in the memory of the vehicle ECU, a plurality of different vehicle group sensor keys each for a group of vehicles;
in response to the request for the subscription, transmitting, by the vehicle subscription server, a subset of the plurality of vehicle group sensor keys to the information application; and
