Query: A multi-layered blockchain framework for smart mobility data-markets   Blockchain has the potential to render the transaction of information more
secure and transparent. Nowadays, transportation data are shared across
multiple entities using heterogeneous mediums, from paper collected data to
smartphone. Most of this data are stored in central servers that are
susceptible to hacks. In some cases shady actors who may have access to such
sources, share the mobility data with unwanted third parties. A multi-layered
Blockchain framework for Smart Mobility Data-market (BSMD) is presented for
addressing the associated privacy, security, management, and scalability
challenges. Each participant shares their encrypted data to the blockchain
network and can transact information with other participants as long as both
parties agree to the transaction rules 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 data-market. In a case
study of real-time mobility data sharing, we demonstrate the performance of
BSMD on a 370 nodes blockchain running on heterogeneous and
geographically-separated devices communicating on a physical network. We also
demonstrate how BSMD ensures the cybersecurity and privacy of individual by
safeguarding against spoofing and message interception attacks and providing
information access management control.
