Development of a speed-limit enforcement system with particular care for driver privacy and anonymity. Based on an application of identity-based encryption and homomorphic commitments, a driver's identity can be processed in a way that is implicitly constrained to the mere detection of a speed limit violation. Using shared information that is distributed over the components of the system, we can assure protection of an identity even against insider attacks, up to the point where evidence of a speed limit violation is available.
