Replication is NOT Needed: SINGLE Database, Computationally-Private Information Retrieval
We establish the following, quite unexpected, result: replication of data for the computational Private Information Retrieval problem is not necessary. More speciically, based on the quadratic resid-uosity assumption, we present a single database, computationally-private information-retrieval scheme with O(n) communication complexity for any > 0.
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...
متن کاملA Graph-Based Information Retrieval Model
The goal of information retrieval is to effectively retrieve documents relevant to users’ queries. A variety of models and techniques have been proposed over the past 50 years. In this research, we introduce a novel, graph-based approach to information retrieval. Its computation is fast and scalable, and its structure is flexible to incorporate many performance enhancement techniques. The perfo...
