WiSec 2011 demo: PRECIOSA PeRA -- practical enforcement of privacy policies in intelligent transportation systems

Cooperative Intelligent Transportation Systems must incorporate privacy-enhancing mechanisms to gain public acceptance. The PRECIOSA Privacy-enforcing Runtime Architecture (PeRA) provides a data-centric protection chain, which ensures that ITS components process data according to attached user-defined privacy policies. PeRA instances constitute a distributed privacy middleware that evaluates privacy policies to mediate data access by applications. An integrity protection layer creates a distributed policy enforcement perimeter between ITS nodes to prevent circumvention of policies. The PeRA has been implemented as a proof-of-concept prototype.
