Abstract

See full text

This document describes techniques that prevent the sharing or leakage of user information. In one aspect, a method includes receiving, by a first MPC server, a request for a selection criterion of at least one interest group to which a user of a client device belongs. The received request does not reveal an identifier of the client device to the first MPC server. In response to receiving the request, the first MPC server determines a set of ordered selection criterion of the at least one interest group retrieved from a cache of the first MPC server. The set of ordered selection criterion is transformed into a set of key/value pairs secured from being revealed by the second MPC server. The first MPC server transmits the set of key/value pairs to the second MPC server with data that enables the second MPC server to identify a key having a highest value.
