The private information retrieval (PIR) problem was first proposed by Chor et al. in 1995, and it is a canonical problem in the study of privacy issues that arise from the retrieval of information fro...
Industrial Feasibility of Private Information Retrieval
Private Information retrieval Survey Implementation
2017/9/1
A popular security problem in database management is how to guarantee to a querying party that the database owner will not learn anything about the data that is retrieved --- a problem known as Privat...
Private Information Retrieval (PIR) allows a client to obtain data from a public database without disclosing the locations accessed. Traditionally, the stress is on preserving sublinear work for the c...
rPIR: Ramp Secret Sharing based Communication Efficient Private Information Retrieval
Private Information Retrieval Secret Sharing
2016/1/26
Even as data and analytics driven applications are becoming increasingly popular, retrieving data from
shared databases poses a threat to the privacy of their users. For example, investors/patients r...
XPIR: Private Information Retrieval for Everyone
Lattices Homomorphic Encryption Private Information Retrieval
2016/1/5
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-di...
On Basing Private Information Retrieval on NP-Hardness
Private Information Retrieval NP-hardness Reductions
2015/12/21
The possibility of basing the security of cryptographic objects on the (minimal) assumption
that NP ⊈ BPP is at the very heart of complexity-theoretic cryptography. Most known results
along th...
Exposing private information by timing web applications
web applications private information
2015/8/5
We show that the time web sites take to respond to HTTP requests can leak private information, using two different types of attacks. The first, direct timing directly measures response times from a we...
Asset Pricing Implications of Pareto Optimality with Private Information
Private Information Pareto Optimality
2015/7/23
We compare the empirical performance of a standard incomplete
markets asset pricing model with that of a novel model with constrained Pareto-optimal allocations. We represent the models’ stochastic d...

Self-Enforcing Trade Agreements and Private Information
Trade Agreements Private Information
2015/7/15
This paper considers self-enforcing trade agreements among privately informed governments.A trade agreement that uses weak bindings (i.e., maximal tari§ levels) is shown to o§er advantages relative to...
Outsourced Symmetric Private Information Retrieval
searchable encryption private information retrieval
2014/3/6
In the setting of searchable symmetric encryption (SSE), a data owner D outsources a database (or document/file collection) to a remote server E in encrypted form such that D can later search the coll...
Efficiency in Games With Markovian Private Information
Repeated Bayesian games efficiency Markov chains
2014/9/10
We study repeated Bayesian games with communication and observable actions in which the players' privately known payoffs evolve according to an irreducible Markov chain whose transitions are independe...
Decentralized Trading with Private Information
Decentralized Trading Private Information asset prices
2014/3/18
The paper studies how asset prices are determined in a decentralized market with asymmetric information about the assets' value. We consider an economy in which a large number of agents trade two asse...
Extended Combinatorial Constructions for Peer-to-peer User-Private Information Retrieval
applications
2012/8/28
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 h...
