Why “Anonymous Data” Might Not Be Anonymous Under GDPR
Introduction
Many companies rely on “anonymous” data but GDPR has a strict definition.
And most data isn’t truly anonymous.
1. Pseudonymous ≠ Anonymous
Data is not anonymous if it can be:
-
Re-identified
-
Linked
-
Combined
2. Common Examples That Are NOT Anonymous
-
IP addresses
-
Device IDs
-
Analytics identifiers
-
Hashed emails
3. Re-Identification Risk Matters
If re-identification is reasonably possible, GDPR applies.
4. Why This Impacts Consent
If data isn’t anonymous:
-
Consent may be required
-
Transparency is mandatory
-
Users have rights
5. Cookiepal Helps Prevent False Assumptions

-
