What is Pseudonymization?

Pseudonymization replaces identifiers with pseudonyms so data cannot be linked to individuals without separately held keys, reducing privacy risk.

Understanding Pseudonymization

Pseudonymization is a data protection technique that replaces identifying fields with artificial identifiers, or pseudonyms, so that data can no longer be attributed to a specific individual without additional information kept separately. Unlike anonymization, it is reversible when the separate key is available, and under the GDPR pseudonymized data remains personal data subject to protection. It reduces privacy risk while preserving data utility for analytics and processing.
