Abstract
A system for performing private information retrieval may include a data requesting computer that is configured to receive a query string, homomorphically encrypt the query string to generate an encrypted query, transmit the encrypted query to a data repository computer, and receive resultant encrypted datasets. The data repository computer may be configured to access a database comprising a plurality of datasets, receive the encrypted query, and perform a search of the plurality of datasets to identify the resultant encrypted datasets that include data that matches the encrypted query for provision to the data requesting computer. The search may be performed such that encryption of the encrypted query is maintained while performing computational operations of the search.
