Title
Towards Secure And Practical Location Privacy Through Private Equality Testing
Abstract
In this paper, we propose a practical, privacy-preserving equality testing primitive which allows two users to learn if they share the same encrypted input data. Our protocol assumes no trust on a third party and/or other peers, and it is specifically suited for low-min entropy data (i.e., data that can be exhaustively searched by an attacker), such as encrypted users locations. We demonstrate that our primitive is secure and efficient: Two public-key exponentiations are required, per each user, for each equality testing. We give implementation results, showing that our primitive is practical in a multiple users scenario. Finally, we describe how we could use our primitive as a building block for a proximity testing buddy-finder service for social networks.
