Biometric enrolment
Your face, voice and fingerprints, taken and kept longer than the moment needs.
Understand it
Banks, airports, phones and shops increasingly capture biometrics - face, voice, fingerprint, even how you walk. Unlike a password, you can’t change your face if the record leaks, and it is often kept far longer than the transaction that needed it. Convenience now, a permanent identifier later.
How to spot it
Any point asking you to scan your face, record your voice or press a fingerprint is enrolling a biometric somewhere.
Close the gap
- Use a PIN or passcode instead of face or voice where you are given the choice.
- Prefer biometrics that stay on your device (as phones do) over ones sent to a company.
- Ask how long a biometric is kept, and whether you can decline or delete it.
- Be wary of “fun” apps that scan your face - that is a face record handed over.
What to do about it
Health data is sensitive and hard to claw back once it's shared. In the UK your main lever is the NHS National Data Opt-Out, which limits how your records are used beyond your direct care.
