XPIR : Private Information Retrieval for Everyone
A Private Information Retrieval (PIR) scheme is a protocol in which a user retrieves a record from a database while hiding which from the database administrators. PIR can be achieved using mutually-distrustful replicated databases, trusted hardware, or cryptography. In this paper we focus on the later setting which is known as single-database computationally-Private Information Retrieval (cPIR)...

متن کاملEfficient Private Information Retrieval
Informally, private information retrieval for k >= 1 databases (k-PIR) is an interactive scheme that enables a user to make access to (separated) k replicated copies of a database and privately retrieve any single bit out of the n bits of data stored in the database. In this model, “privacy” implies that the user retrieves the bit he is interested in but releases to each database nothing about ...
متن کاملPractical Private Information Retrieval
In recent years, the subject of online privacy has been attracting much interest, especially as more Internet users than ever are beginning to care about the privacy of their online activities. Privacy concerns are even prompting legislators in some countries to demand from service providers a more privacy-friendly Internet experience for their citizens. These are welcomed developments and in s...
متن کاملNearly Private Information Retrieval
A private information retrieval scheme is a protocol whereby a client obtains a record from a database without the database operators learning anything about which record the client requested. This concept is well studied in the theoretical computer science literature. Here, we study a generalization of this idea where we allow a small amount of information about the client’s intent to be leake...
