Abstract

Various techniques for collection and processing of motor vehicle telematics data and establishing control over access to the telematics data are disclosed herein. In an example, a communication device (e.g., a computing device) operated by an owner or operator of a motor vehicle operates to receive telematics data from a telematics system, generate and transmit a derived indication of the telematics data (e.g., using a hash of the data), receive and process a request for information from the telematics data, and generate and transmit an answer and proof of the answer validity in response to the request for information. In an example, the proof of the answer validity may be provided as a zero knowledge proof. The proof may be verified using the derived indication of the telematics data, such as from an indication that is stored in a public distributed blockchain that is auditable and unalterable.
