Abstract: Methods and systems implement replacement of features extracted from captured data at edge devices before the captured data is collected at a cloud computing system. Based on operation of an identifying system including one or more learning models, features dispositive to matching features against user records may be determined. A feature synthesizing model may be trained based on random, synthetic, and/or generic data to generate synthetic features which are not identifying of users. The identifying features from the captured data may be replaced with these synthetic features before the captured data is transported across a privacy boundary to a cloud computing system for backend computations supporting IoT services by one or more learning models. In this manner, data may be collected and stored in a manner which avoids individual users being exposed by inspection, while still maintaining utility in allowing identifying models to function and user profiles to be updated.
