Maybe a morbid question but could they theoretically unlock the phone with the fingerprint of his corpse or do those sensors require current (like a touchscreen does)? I'm asking because I heard in the US law enforcement can force you to unlock your device with biometrics but I wonder if that only works if the subject is alive.
- delecti 2y agoSeems the answer is yes, but only if you do the unlock very quickly after death. The reason seems to be what you suspected, that the fingerprint sensors require capacitance which is only maintained while we're alive. https://www.livescience.com/62393-dead-fingerprint-unlock-phone.html https://www.livescience.com/62393-dead-fingerprint-unlock-ph...

- neutered_knot 2y agoIt depends on the sensor and probably the state of the subject. This is called "liveness detection" and there is an article I found explianing the basics at: https://www.thalesgroup.com/en/markets/digital-identity-and-security/government/inspired/liveness-detection https://www.thalesgroup.com/en/markets/digital-identity-and-...
