Apple’s Touch ID may mean U.S. iPhone 5s users can’t ‘take the fifth’

“There’s a lot of talk around biometric authentication since Apple introduced its newest iPhone, which will let users unlock their device with a fingerprint,” Marcia Hoffman writes for Wired. “Given Apple’s industry-leading position, it’s probably not a far stretch to expect this kind of authentication to take off. Some even argue that Apple’s move is a death knell for authenticators based on what a user knows (like passwords and PIN numbers).”

MacDailyNews Take: It is.

“While there’s a great deal of discussion around the pros and cons of fingerprint authentication — from the hackability of the technique to the reliability of readers — no one’s focusing on the legal effects of moving from PINs to fingerprints,” Hoffman writes. “Because the constitutional protection of the Fifth Amendment, which guarantees that ‘no person shall be compelled in any criminal case to be a witness against himself,’ may not apply when it comes to biometric-based fingerprints (things that reflect who we are) as opposed to memory-based passwords and PINs (things we need to know and remember).”

Hoffman writes, “If Apple’s move leads us to abandon knowledge-based authentication altogether, we risk inadvertently undermining the legal rights we currently enjoy under the Fifth Amendment. Here’s an easy fix: give users the option to unlock their phones with a fingerprint plus something the user knows.”

  1. “give users the option to unlock their phones with a fingerprint plus something the user knows.”

    Um, I thought that is what they have done. Up to five finger prints plus one pin or passcode.

    1. “give users the option to unlock their phones with a fingerprint plus something the user knows.”

      This is the dumbest idea yet. The whole purpose of Touch ID is a more secure and faster authentication without having to remember pins, passwords, etc. So now Hoffman wants to ADD pins and passwords to fingerprint IDs?

      Stupid.

  2. I don’t understand how this would change Fifth Amendment cases. If a law official asks a defendant to unlock their phone, they can refuse citing their Fifth Amendment right against self-incrimination. Why would the phone’s unlocking mechanism being fingerprint or password make a legal difference here?

    1. It wouldn’t. The police can forcibly take your fingerprints at your arrest for identification purposes, but they can’t force you to unlock a safe, for example. They can get a warrant and break into the safe (or iPhone), but that’s another matter entirely.

    2. Since the government ignores the rest of the constitution why would you expect Fifth Amendment protection? If anyone in the government wants your information they’ll just take it as they do from every other source.

      1. I was looking at from a strictly legal standpoint, like the article.

        If we do assume laws would be broken to obtain private information, I think the finger scan is actually more secure than just a password, and the two combined in two-factor authentication would be even more secure. A password can be stolen in many ways including simple surveillance of the password being entered. Stealing a finger reading is a bit more involved because the person would have to be forced or tricked into physically unlocking the device in person.
