Overview
Pseudonymization replaces identifying data with artificial identifiers (pseudonyms). Unlike anonymization, pseudonymization is reversible if one has access to the 'key' that links the pseudonym back to the original data.
GDPR Context
The GDPR encourages pseudonymization as a way to reduce the risks associated with data processing while still allowing the data to be used for analysis or research.
Benefits
- Enhanced Privacy: Reduces the impact of a data breach.
- Utility: Allows for data to be linked across different systems without exposing the actual identity of the individual.
