What is a potential outcome of pseudonymized data under GDPR?

Pseudonymized data retains its status as personal information under the General Data Protection Regulation (GDPR) because it still can be linked back to an individual, albeit indirectly. Pseudonymization involves processing personal data in a way that it cannot be attributed to a specific individual without the use of additional information, which is kept separate and secured. However, this does not change the fundamental nature of the data — it remains personal by definition, as it can still be re-identified if the supplementary information is accessible.

This distinction is crucial, as it means that organizations are still required to comply with GDPR principles and obligations when handling pseudonymized data. They must ensure appropriate protection measures are in place and respect the data subjects' rights, maintaining compliance as if the data were fully identifiable.
