Inferential Learning & Privacy

As artificial intelligence algorithms make rapid strides in deriving seemingly hidden inferences from outwardly harmless data, the privacy of individuals is often compromised, not through hacking or identity theft but through learning and inference. Legal protections for privacy only extend to information that is stolen, not that which is inferred. Our research develops data processing and decision making mechanisms backed by statistical inference theory that balance optimally the level of desired privacy and the loss in utility in the data or decision making processes.
