Jiayang Liu, Jingguo Bi · 2016
A private information retrieval (abbreviated as PIR) protocol deals with the schemes that allow a user to retrieve privately an element of a non-replicated database. The security of PIR protocol is that the user wants to retrieve information in a database without the database knowing which information has being retrieved. This is widely applied in medical files, video or songs databases or even stock exchanges share prices.
