This book deals with Private Information Retrieval (PIR) a technique allowing a user to retrieve an element from a server in possession of a database without revealing to the server which element is retrieved. PIR has been widely applied to protect the privacy of the user in querying a service provider on the Internet. For example by PIR one can query a location-based service provider about the nearest car park without revealing his location to the server. The first PIR approach was introduced by Chor Goldreich Kushilevitz and Sudan in 1995 in a multi-server setting where the user retrieves information from multiple database servers each of which has a copy of the same database. To ensure user privacy in the multi-server setting the servers must be trusted not to collude. In 1997 Kushilevitz and Ostrovsky constructed the first single-database PIR. Since then many efficient PIR solutions have been discovered. Beginning with a thorough survey of single-database PIR techniques this text focuses on the latest technologies and applications in the field of PIR. The main categories are illustrated with recently proposed PIR-based solutions by the authors. Because of the latest treatment of the topic this text will be highly beneficial to researchers and industry professionals in information security and privacy.
