PeRA: Individual Privacy Control in Intelligent Transportation Systems
نویسندگان
چکیده
In the domain of Intelligent Transportation Systems (ITS) manufacturers and service providers start to implement and deploy plenty of (new) applications running on a vehicle. These applications involve the user and external services. Therefore, we must incorporate mechanisms providing the individual for controlling his/her privacy. Existing approaches only consider to control the event of data access using a central instance. In contrast, we consider to implement individual privacy requirements for the complete data flow of distributed systems. The Privacy-enforcing Runtime Architecture (PeRA) provides a holistic privacy protection approach, which implements user-defined privacy policies. A data-centric protection chain ensures that ITS components process data according to attached privacy policies. PeRA instances constitute a distributed privacy middleware, which evaluates privacy policies to mediate data access by applications. The PeRA architecture includes an integrity protection layer to create a distributed policy enforcement perimeter between ITS nodes, which prevents the circumvention of policies. We implemented the PeRA architecture as a proof-of-concept prototype.
