Episode 45 — Apply anonymization and pseudonymization with honest limits and verification (Domain 4C-3 Anonymization and Pseudonymization)
This episode explains anonymization and pseudonymization in the way CDPSE expects: as risk-reduction techniques with strict limits, not magic labels that eliminate obligations. You’ll learn the functional difference between truly anonymized data and data that is merely pseudonymized, masked, or tokenized, and you’ll see why identifiability depends on context, auxiliary data, and re-identification feasibility. We’ll work through scenarios like sharing datasets for analytics, releasing aggregated reports, and de-identifying logs, highlighting where linkage risk remains even when direct identifiers are removed. You’ll also learn how to verify claims with practical tests and documentation, such as threat modeling the re-identification pathway, assessing k-anonymity-like exposure in practical terms, and ensuring separation of key material, access controls, and retention rules, so exam answers reflect defensible engineering judgment.
