  A blockchain framework is presented for addressing the privacy and security
challenges associated with the Big Data in smart mobility. It is composed of
individuals, companies, government and universities where all the participants
collect, own, and control their data. Each participant shares their encrypted
data to the blockchain network and can make information transactions with other
participants as long as both party agrees to the transaction rules (smart
contract) issued by the owner of the data. Data ownership, transparency,
auditability and access control are the core principles of the proposed
blockchain for smart mobility Big Data.
