Privacy-Enhanced Searches Using Encrypted Bloom Filters
Steven M. Bellovin William R. Cheswick
It is often necessary for two or more or more parties that do not fully trust each other to selectively share data. We propose a search scheme based on Bloom filters and Pohlig-Hellman encryption. A semi-trusted third party can transform one party's search queries to a form suitable for querying the other party's database, in such a way that neither the third party nor the database owner can see the original query. Furthermore, the encryption keys used to construct the Bloom filters are not shared with this third party. Provision can be made for third-party ``warrant servers'', as well as ``censorship sets'' that limit the data to be shared.
