Feds Walk Into a Building, Demand Everyone's Fingerprints To Open Phones (dailyherald.com)

An anonymous Slashdot reader quotes the Daily Herald: Investigators in Lancaster, California, were granted a search warrant last May with a scope that allowed them to force anyone inside the premises at the time of search to open up their phones via fingerprint recognition, Forbes reported Sunday. The government argued that this did not violate the citizens' Fifth Amendment protection against self incrimination because no actual passcode was handed over to authorities...

"I was frankly a bit shocked," said Andrew Crocker, a staff attorney at the Electronic Frontier Foundation, when he learned about the scope of search warrant. "As far as I know, this warrant application was unprecedented"... He also described requiring phones to be unlocked via fingerprint, which does not technically count as handing over a self-incriminating password, as a "clever end-run" around constitutional rights.

    ... keep holding it down.

    Seriously, this is such an unconscionable violation of basic privacy that even people who have done nothing wrong should automatically have that reaction. And anybody who has done something wrong should know better than to use a fingerprint for unlocking anyway. What was this supposed to prove other than that they have a judge who will rubber-stamp any order no matter how appalling?

    Pattern required to start device before fingerprint reader will work.

    if the iPhone reboots, the key code must be entered as touchID does not work. Passwords are still protected by the 4th amendment in the US, right?

      This is the same for any Android phone that has fingerprint recognition.

    In a premises search, they can compel an unlock of phones by fingerprint, assuming you lock your phone that way.

    The specific legal decision was the 1988 John DOE, Petitioner v. UNITED STATES. 487 U.S. 201 (108 S.Ct. 2341, 101 L.Ed.2d 184) decision.

    It came down to whether on not an affirmative action was required on the part of someone, or if it was a non-affirmative action. Use of a key on a safe or lockbox is not affirmative. Being forced to enter the combination is not affirmative; it's tantamount to compelled testimony.

    Here's the part of the decision of interest:

    A defendant can be compelled to produce material evidence that is incriminating. Fingerprints, blood samples, voice exemplars, handwriting specimens, or other items of physical evidence may be extracted from a defendant against his will. But can he be compelled to use his mind to assist the prosecution in convicting him of a crime? I think not. He may in some cases be forced to surrender a key to a strongbox containing incriminating documents, but I do not believe he can be compelled to reveal the combination to his wall safe —- by word or deed.

    Moral of this story: use a pin code, rather than using the fingerprint unlock. It may be a cool feature, but it offers you no legal protection.
