A scalable architecture for peer privacy on the Web

Spyros Kotoulas
Ruud Stegers

We consider the privacy implications of exchanging Web data and present the design of a peer-to-peer discovery mechanism with strong privacy guarantees. Its benefits are that it does not rely on a trusted third party, spreads the computational cost among participants and places minimal restrictions on privacy policies. Furthermore, it provides scalability both in terms of system size and level of privacy offered. We outline an implementation that relies on two overlays: a distributed hash table for discovery and an anonymising overlay. Finally, we evaluate the proposed mechanism against a number of privacy threats and analyse its complexity.
