Synthetic Data
Artificially generated data that mimics real-world data patterns without containing actual personal information.
Definition
Data artificially generated by purpose-built mathematical or ML models trained on source data to reproduce statistical properties and utility of the original dataset without preserving exact original records. The Guide treats synthetic data as a Privacy Enhancing Technology but notes it may still carry re‑identification risk and thus requires privacy risk assessment.
