Abstract
One embodiment provides a system for noise addition to enforce data privacy protection in a star network. In operation, participants may add a noise component to a dataset. An aggregator may receive the noise components from the plurality of participants, compute an overall noise term based on the received noise components, and aggregate values using the noise components and overall noise term.
