Common questions

What counts as biometric data 'used for unique identification' under Article 9?+

Data such as fingerprint templates, facial recognition vectors, or iris scans processed specifically to identify a single individual falls within the special category; a photograph stored without any matching or identification processing generally does not trigger the same heightened protection.

How does Article 9's consent requirement affect law-enforcement biometric databases operating in the EU?+

Law-enforcement processing is typically governed by separate legal instruments rather than GDPR consent directly, but private companies building or supplying biometric identification tools used in or affecting the EU still need an Article 9 legal basis, which is why commercial facial-recognition deployments there face additional scrutiny.

Why does Article 9 matter to a forensic case involving a commercial face-recognition tool?+

If the underlying database or matching tool was built by scraping or processing biometric data without a valid Article 9 basis, evidence or leads derived from that tool can face legal challenge in EU-connected proceedings on data-protection grounds, independent of the identification's technical accuracy.
