1. A computer implemented method comprising: collecting at a trusted service, from a vehicle, sensor data together with an attestation of the authenticity of the data, which attestation does not reveal the identity of the vehicle owner; identifying data from each of at least two sensors and associating said data with a subscriber of said data; sending sensor data from the vehicle to a server for distribution to subscribers; receiving a first public key from a first subscriber, encrypt different sensor data with said first public key; receiving a second public key from a second subscriber, encrypt different sensor data with said second public key; authenticating the sensor data from said vehicle at the trusted service; reporting the collected and authenticated sensor data from said vehicle without identifying the vehicle owner; sending different encrypted information to two different subscribers depending on a subscriber's authority to receive information granted by an owner of the vehicle; encrypting data sent to the first subscriber using said first key and encrypting data sent to the second subscriber using said second key; and preventing a subscriber from identifying a vehicle owner using privacy preserving public keys to verify data as coming from a pre-defined group of vehicles.
