pseudonymization
Data identity substitution
Pseudonymization is replacing identifying information with artificial identifiers, allowing data to be processed without revealing who it belongs to.
Unlike full anonymization, pseudonymized data can be re-linked to individuals if you have the key: The hospital pseudonymized patient records before sharing them with researchers.
The term appears frequently in privacy regulations like GDPR.
