Privacy‑Enhancing Technologies (PETs)
Privacy
Category of technical methods that reduce privacy risk during collection, processing, or sharing.
Definition
PETs include techniques such as encryption, differential privacy, secure multi-party computation, secure aggregation, federated learning, and tokenization. They are often combined with governance and access control.
Why this matters
Why it matters: PETs can reduce exposure while preserving utility, but they require correct implementation and threat modeling.
Example
Example: Combine secure aggregation + differential privacy to produce analytics while limiting inference about any individual.
