ABSTRACT
The thirst of acquiring and sharing the knowledge has been increased exponentially in these days due to the availability of the Internet at the finger tips. As a consequence, the need of privacy at various levels and various contexts has been comprehensively studied by various cryptographers. One of the user privacy preserving concepts called Private Information Retrieval (PIR) also provides user privacy at various levels. Several years of efforts on PIR have succeeded to provide almost practical communication efficient privacy preserving solutions.
