Query: Immutable Autobiography of Smart Cars   The popularity of smart cars is increasing around the world as they offer a
wide range of services and conveniences.These smart cars are equipped with a
variety of sensors generating a large amount of data, many of which are
sensitive. Besides, there are multiple parties involved in a lifespan of a
smart car ,such as manufacturers, car owners, government agencies, and
third-party service providers who also produce data about the vehicle. In
addition to managing and sharing data amongst these entities in a secure and
privacy-friendly way which is a great challenge itself, there exists a trust
deficit about some types of data as they remain under the custody of the car
owner(e.g. satellite navigation and mileage data) and can easily be
manipulated. In this paper, we propose a blockchain supported architecture
enabling the owner of a smart car to create an immutable record of every data,
called the auto biography of a car, generated within its lifespan. We also
explain how the trust about this record is guaranteed by the immutability
characteristic of the blockchain. Furthermore, the paper describes how the
proposed architecture enables a secure and privacy-friendly sharing of smart
car data between different parties in a secure yet privacy-friendly manner.
