Basically, a verbal voice print-authenticated lockdown code, delivered via your digital assistant (Siri, Google Assistant, Alexa, etc) which immediately locks the phone down and disables biometric unlocking.

A modern-day panic PIN Could be interesting. Law enforcement might not care for it though.

I was debating with myself on calling it Verbal Panic PIN.

Nice, esp. if les enfants get hold of your work phone and start trying to find Farmville, par example.

Unfortunately, Le Loi already has deep-fake AI tech and can reverse engineer this p.d.q, especially if you've ever spoken aloud around your always-on phone.

I'd use it anyway, since power-outage (usually) weather-related technology 'supply chain issues' happen more and more often. (side note: do new cars just stop when they lose internet connectivity during a wildfire, insurrection or other crisis?)

Lock down phrase must include words you've never said before, in an unexpected order, for maximum bafflement.

I’d make the phrase “I can’t, the face I D is broken” - though this may be only a small obstacle to someone who wants to force my compliance. Couple this with the aforementioned "Panic PIN" - once primed by that lock phrase, entering the panic PIN or even an incorrect pin may be programed to wipe the device, trigger a siren, explode*, etc.

Fun fact, courts in U.S.A have upheld the notion that police may NOT legally compel someone to unlock a devices via password or PIN - but ARE allowed to force them to unlock via fingerprint or facial recognition.

I'd seen something about that, regarding the courts and police. It's part of what prompted the idea. I don't *think* they're allowed to gag you.

It's a good idea but only if it's permanent and irrevocable. Otherwise, linky

When I conceived the idea initially I thought of that and considered making a visit to a store that sells them necessary to show ID and have it unlocked, but then I remembered how often certain digital assistants like Bixby and Siri get activated by the wrong person's voice, and so the chance of it accidentally being duress locked is a little too high to make that an easy sell to consumers. That'd happen exactly once before I threw it out a window.
