1. A method of facilitating a subscription to access a subset of vehicle sensor data for a predetermined period of time in a vehicle electronic control unit (ECU) to augment an information application, the method comprises:
generating, by a vehicle subscription server using a public-key cryptosystem, at least one vehicle sensor key and at least one subscription key for the subscription, wherein the at least one vehicle sensor key is specific to a vehicle and sensor, including vehicle make, model, and a sensor feature;
installing, in a memory of the vehicle ECU, the at least one vehicle sensor key and the at least one subscription key that expires after the predetermined period;
in response to a request for the subscription by a mobile device as an advance agreement that permits access to the subset of the vehicle sensor data, transmitting, by the vehicle subscription server, the at least one subscription key;
using the at least one subscription key, by the vehicle ECU, to authenticate the mobile device as having obtained the subscription;
encrypting, by the vehicle ECU, the subset of vehicle sensor data using the at least one vehicle sensor key;
transmitting, by the vehicle ECU, the encrypted subset of vehicle sensor data;
decrypting, by the mobile device, using the at least one subscription key the encrypted subset of vehicle sensor data; and
augmenting, by the mobile device, the information application with the subset of the vehicle sensor data that is specific to the vehicle make, model, and sensor feature.
