Pseudonymization - Distinguishing individuals in a dataset using a unique identifier that does not reveal their real-world identity (UK ICO definition).
In the CIPP/US body of knowledge, Pseudonymization comes up under Chapter 3: Introduction to Technological Aspects of Privacy; Chapter 4: Information Management and Privacy Risk Management.
Pseudonymization in context
- [[Anonymization]] removes identifiability; [[pseudonymization]] masks identity with a unique identifier. (Deidentification: Anonymous vs Pseudonymous and Identifiers)
- A data breach readiness assessment examines the risk of a breach plus the likelihood and severity of a personal data breach, weighing data type, technical safeguards (==encryption, pseudonymization==), effect on data subjects, and potential for malicious use or substantial physical damage.
