Can you opt out of my brain recognizing your face?

Centralized face recognition where a single entity knows everybody a la Facebook would be a dystopian nightmare. Personalized face recognition where everyone has their own instance trained purely on the data they have access to (e.g. Apple's existing Photos face recognition) and only linking that face to the user's Contacts entry for the recognized person, that's not a privacy violation because that's just offloading information from my brain into my personal digital assistant.

Personalised but running on a cloud server, controlled by any third party is a step too close.

Who's to say they won't retain the biometrics long after you requested they remove the data? The standard HN trope is if it's out there it's never deleted. Trusting any corporate with data, given the last ten years, is never wise. Even Apple, busy marketing the privacy high ground.

No doubt someone would make a GDPR case against it though...
