Blockchain for Preserving Privacy in V2X Connected Vehicle Applications in Urban Environments

Trajectory data from connected vehicles (CVs), pedestrians, and micromobility sources such as scooters and bikes is an important input for researchers and policy makers to improve safety and develop innovative location-based applications. To address security and privacy concerns associated with the storage and preservation of this raw data, it must be stored and accessed from a non-proprietary database.

However, obfuscation and encryption techniques on existing cloud-based solutions incur data losses that are inefficient for accurate usage, which is especially detrimental in time-sensitive real-time operations. C2SMART researchers developed a more efficient, secure, blockchain-based system to story mobility data on a distribute ledger. To store this data at scale, researchers leverage InterPlanetary File System (OPFS), a scalable distributed peer-to-peer data storage system, and develop efficient consensus algorithms to prevent users from injecting malicious or fake trajectories into the ledger.
