The good news is apparently that if you were dumb enough to use your fingerprint as your phone security, if you’ve been dead a few days it no longer works. The bad news is…well, obvious. From Ars Technica:
Three different lawyers told Ars said that the Phillip case was troubling, and they all agreed that it’s extremely difficult if not outright impossible for the estate of a dead person to assert an alleged 4th Amendment violation. Or, put another way, dead people have no privacy rights.
What about the messages, etc. from the people he talked to? Do they have privacy rights?
Moral of the story: Think about who you talk to on/with your phone. A warrant against them, to some extent, may expose you as well. And for the love of all that’s holy, don’t use biometric data to “secure” a device that can’t BE secured.
