Claim 14:
15. A system for facilitating a subscription to access a subset of vehicle sensor data for a predetermined period to augment an information application, the system comprises:
a vehicle subscription server configured to generate at least one sensor public key and at least one subscription key using a public-key cryptosystem, each said key having respective predetermined expiration dates, wherein the at least one sensor public key is specific to a vehicle and sensor, including vehicle make, model, and a sensor feature;
a vehicle ECU connected to a plurality of in-vehicle sensors;
a memory of the vehicle ECU to store the at least one sensor public key and the at least one subscription key;
in response to a request for the subscription by the information application as an advance agreement that permits access to the subset of the vehicle sensor data, the vehicle subscription server is configured to transmit the at least one subscription key;
the vehicle ECU is configured to
encrypt the subset of vehicle sensor data using the at least one vehicle sensor key,
transmit the encrypted subset of vehicle sensor data;
the mobile device is configured to
decrypt, using the at least one subscription key, the encrypted subset of vehicle sensor data, and
