ABSTRACT
This paper proposes an efficient and effective "Locality Preserving Mapping" scheme that allows text databases representatives to be mapped onto a global information retrieval system such as Peer-to-Peer Information Retrieval Systems (P2PIR). The proposed approach depends on using Locality Sensitive Hash functions (LSH), and approximate min-wise independent permutations to achieve such task. Experimental evaluation over real data, along with comparison between different proposed schemes (with different parameters) will be presented in order to show the performance advantages of such schemes.

    We consider user-private information retrieval (UPIR), an interesting alternative to private information retrieval (PIR) introduced by Domingo- Ferrer et al. In UPIR, the database knows which records have been retrieved, but does not know the identity of the query issuer. The goal of UPIR is to...
