@dangoodin@infosec.exchange @adamshostack@infosec.exchange Keep in mind that a search warrant authorizes law enforcement to do things, but does not (directly) compel anyone else to do anything (except not actively interfere). If they want a password, they would need a court order to the target, which could then be litigated as to whether providing it would be testimonial (and 5A protected).

Interesting. Any idea what happens if law enforcement in possession of a warrant instructs the journo to provide a biometric and she refuses? I mean, can LE physically place her finger on the scanner if she refuses to comply with an instruction?

@dangoodin@infosec.exchange @adamshostack@infosec.exchange The warrant authorizes them to obtain the biometric, but doesn't compel the journalist to cooperate. For that they need an order to the journalist (which they could probably get, but it's not the search warrant).

OK, thanks.

@dangoodin@infosec.exchange @mattblaze@federate.social @adamshostack@infosec.exchange Does this perhaps make faceid slightly more risky than fingerprinting (e.g. you can ball up your hands and refuse consent to have your finger scanned but hiding your face while handcuffed is difficult)?

Is there case law on this yet?

Closing your eyes prevents face ID from working in all cases I'm aware of. Still pretty easy to do that, even in cuffs (which I'm guessing the journo was not).

@rrb@infosec.exchange @dangoodin@infosec.exchange @azonenberg@ioc.exchange @adamshostack@infosec.exchange This is literally the origin of the term "mug shot". Arrestees would scrunch up their faces when photographed to make themselves less recognizable.
