1. A method of preserving privacy in a data set used to estimate information configured to be used by a third party, the method comprising the steps of:
receiving an initial information data set and a user's privacy setting, the user's privacy setting including one or more privacy instructions defining conditions for sharing regarding the initial information data set;
using the initial information data set and the user's privacy setting as input, producing a privacy-preserving stochastic map using an updated prior knowledge data set, the user's privacy setting, and extraction noise statistics as inputs and then applying the privacy-preserving stochastic map to an extracted initial information data set to produce an adjusted information data set; and
using the adjusted information data set and the privacy-preserving stochastic map as inputs, applying a stochastic inference algorithm to produce an estimate of the initial information data set and an estimation error value, wherein the adjusted information data set is constrained to meet every condition defined within the user's privacy setting.
