The legal situation is more complex and nuanced than the headline implies, so the article is worth reading. This adds another ruling to the confusing case history regarding forced biometric unlocking.

9 points

This is the best summary I could come up with:


The US Constitution’s Fifth Amendment protection against self-incrimination does not prohibit police officers from forcing a suspect to unlock a phone with a thumbprint scan, a federal appeals court ruled yesterday.

The ruling does not apply to all cases in which biometrics are used to unlock an electronic device but is a significant decision in an unsettled area of the law.

Judges rejected his claim, holding “that the compelled use of Payne’s thumb to unlock his phone (which he had already identified for the officers) required no cognitive exertion, placing it firmly in the same category as a blood draw or fingerprint taken at booking.”

Payne conceded that “the use of biometrics to open an electronic device is akin to providing a physical key to a safe” but argued it is still a testimonial act because it “simultaneously confirm[s] ownership and authentication of its contents,” the court said.

The Supreme Court “held that this was not a testimonial production, reasoning that the signing of the forms related no information about existence, control, or authenticity of the records that the bank could ultimately be forced to produce,” the 9th Circuit said.

The Court held that this act of production was of a fundamentally different kind than that at issue in Doe because it was “unquestionably necessary for respondent to make extensive use of ‘the contents of his own mind’ in identifying the hundreds of documents responsive to the requests in the subpoena.”

People who demand constant internet connect when thy go out have a higher probability of having too much personal information on their phone. It’s a difference in mindset or mentality.

Cell service is overrated. Given the amount of people in public that are either scrolling or on some form of a social media shows having data service is not as important as people think it is. I have a GrapheneOS phone for listening to music and if I want to check for public wi-fi for a specific task but most days I never connect online when I am out and I’ve never signed up for a cell data plan before.

Life can be happier when someone is out in public and can’t check messages, that usually can wait anyways for a few hours, and they can enjoy the world around, not what’s on a screen.

Most traffic these days goes over secure channels. Any time the website you’re accessing is HTTPS, they can see that you’re accessing that website, but they can’t see which pages you’re on our read what they say, or what you submit.

The exception is if they get you to install their own certificate to allow them to man-in-the-middle you. Laws in some authoritarian countries already require devices have root certificates that allow the government to spy on everything. And the EU is currently considering the same. Which should be a major concern for any European residents.

Yeah, it’s like if you kept a bunch of illegal things in a safe the authorities have the authority to force you to unlock the safe.

Authorities with a warrant can drill into a safe to get to its contents. That’s legally distinct from forcing someone to unlock the safe by entering the combination. It takes some mental effort to enter a combination, so it counts as “testimony”, and in the USA people can’t be forced to testify against themselves.

The parallel in US law is that people can be forced to unlock a phone using biometrics, but they can’t be forced to unlock a phone by entering a passcode. The absurd part here is that the actions have the same effect, but one of them can be compelled and the other cannot.

It’ll be interesting to see if it applies to facial recognition. In iOS, at least, you need to look at the phone to unlock it. That’s an intentional action. If you look to the side or close your eyes, it won’t work.

So if you’re conscious, you can’t easily be forced to unlock the phone with your face and eyes if you’re able to resist. But if you’re unconscious, then maybe they could use your face (assuming your eyes aren’t rolled back into your head because the cops gave you brain damage.)

They can also compel you to provide a key to the safe, should one exist.

The issue constantly is something you have vs something you know. They also can compel you to provide a document or item from within the safe, if they know that the item exists.

Hopefully it gets overturned and your compulsion to stick your finger on the devices requires a warrant.

I’m in partial agreement with @gomp@lemmy.ml, they should be allowed to take your fingerprint and then apply that fingerprint to a device. Or get a warrant to make you stick you finger on the device. Recording your fingerprint is just collecting data to investigate a crime, it generates a record. Sticking your finger on a device is making you participate in the investigation, and generates no investigative record other than “device did/didn’t unlock”.

Biometric is high security against thieves and nosy girlfriends, not kidnappers or cops apparently. You need to be physically present for most of them which means it can’t be done without you knowing. The problem arises when the person who wants access also has access to you.

Also not a lawyer or a US person, but from listening to American tech media, this has been an issue of some debate for a decade or more now.

The trick lies in their 5th amendment right against self-incrimination. Police cannot require you to give your PIN because that would violate 5th amendment rights. It has been ruled in some parts of America (but the ruling in other parts has been the opposite, IIRC) that you can be forced to give biometric unlocks. In my opinion this is kinda silly and inconsistent. It might be in line with the letter of the law, but it’s certainly not in keeping with its spirit.

As an American and avid rights understander, it is not the 5th Amendment which this risks violating (which you did cite correctly), but the 4th Amendment, which guarantees protection from undue searches and seizures of your person, property, or effects. This is the whole reason for the warrant requirement and the reason you hear us bitching whenever something comes up that lets police or agents of the government acquire non-public access to information or property in a warrantless way.

An example: the police are investigating Mary’s death and suspect you of having planned the murder in the Notes app on your phone, so they want to get into your phone. Without a court order (warrant), you have to give them permission. With the court order, you must give the passcode and/or unlock the phone.

Now, at this point, if your passcode happened to be ‘I killed John02&’ you could argue 5th Amendment protection because divulging the information would incriminate yourself in the crime, or a different crime.

I believe the reason the 5th is usually referenced is that this usually comes up in situations where the 4th is already not relevant. Either because there already is a warrant, or because you’re crossing a border (which IMO seems like an incredibly sketchy excuse and would likely not have been accepted by those who originally penned the 4th amendment, but is at least well-established law at this point).

With the court order, you must give the passcode and/or unlock the phone

The thing is, case law has determined that this is not the case. Passcodes are fairly well protected, from what I’ve heard. You cannot be made to divulge them anywhere in the US, because of the 5th amendment, even with a warrant. Case law is more split on whether biometrics should be offered the same protection.

Though again, this is all my understanding of it having heard it third hand from Americans. Mostly from Americans who themselves are not legal experts, though I think I’ve at least a couple of times heard it directly from lawyers.

The bigger problem IMO is that the Constitution does not universally apply at or within 100 miles of a border, which is where apparently 72% of the population lives.

I just wish you could setup logic for this. Pulling out your phone to hold the power button for 3 seconds and then tapping the lockdown button is slow, very obvious, and likely to be prevented by an attacker.

Would be great if I could set it up to lockdown on a specific finger, or a specific number of presses on an analog button. Or even like if I leave a WiFi network or some other arbitrary condition.

This article and similar threads keeps popping up in my feed, so I’m going to keep spreading this tip around. (I’m using Android.)

I use tasker to automatically lockdown my phone based on accelerometer and Bluetooth. A sharp tap to my phone or being disconnected from Bluetooth is enough to lockdown my phone and disable all biometric access. I dialed in the sensitivity so that it doesn’t take much, just a tap on my pocket, being set down a little too aggressively, pulled from my car and thrown to the ground is all it takes. I set it to notify me with a quick vibrate when it does this for a little added confidence that it is behaving as expected.

For a little added effort I can have tasker snap a photo that gets backed up to the cloud any time there is a failed unlock attempt, just be prepared for some unflattering photos of yourself looking like an aging male boomer posting selfies to the facebook.

Not sure about all phone models, but at least with mine, if I switch it off then it requires a PIN, rather than biometrics, upon being switched back on. Thus if the police arrive, immediately switching off your phone could be a sensible thing to do

Reminder that on an iPhone, if you hold the Volume Up and Power buttons simultaneously for several seconds, the phone will vibrate and will require the PIN or password next time you unlock it, not Face/TouchID. This happens whether the screen is on or off, so you can discretely do it in your pocket.

Absent an idiotic carrier/mfg skin that disables the feature, you just long-press power then click “lockdown”.

Or reboot the device. Rebooting the device will also leave it encrypted if your device has encryption (the PIN/password is needed to decrypt, essentially).
