GDPR Glossary

What is Biometric data?

Data from physical or behavioural traits — like fingerprints or facial geometry — used to uniquely identify a person.

Biometric data results from specific technical processing of physical, physiological or behavioural characteristics — fingerprints, facial geometry, iris scans, voice patterns — that allow or confirm unique identification.

When used to identify someone, it is special-category data and needs an Article 9 condition on top of a lawful basis.
