Welcome to the resource topic for 2017/044

Title:
Anonymous contribution of data

Authors: Matthew McKague, David Eyers

Abstract:

Many application domains depend on the collection of aggregate statistics from a large number of participants. In such situations, often the individual data points are not required. Indeed participants may wish to preserve the privacy of their specific data despite being willing to contribute to the aggregate statistics. We propose a protocol that allows a server to gather aggregate statistics, while providing anonymity to participants. Our protocol is information theoretically secure so that the server gains no information about participants’ data other than what is revealed by the aggregate statistics themselves.
