Abstract
Techniques of information sharing involve processing queries from exchanges with multiple, non-colluding servers. Along these lines, each server stores a share of the query data such that readable query data may be reproduced only through combining the shares stored on a minimum number of the servers. In addition, a client wishing to submit a query encrypts any query input as well as a query function that provides an answer to the query. The client then sends a portion of the garbled query function to each of the servers. Each of the servers then evaluates their respective portion of the garbled query function using Yao's protocol in a serial manner so that one of the servers produces a garbled output. The client then determines the answer to the query by decoding the garbled output.
