- algaexe 9y agoTwins and siblings that look like you are not random people.
- roywiggins 9y agoNow I'm imagining the FBI using its facial-recognition databases and tracking down people who look like the phone owner to wave an iPhone in front of their face.
- epicide 9y agoI'd watch that TV show. "Dylan and Luke are bounty-hunters of a new breed. They have to find the long-lost twins of suspects on FBI's Most Wanted list. On this episode of Face Hunters..."
- MBCook 9y agoBut you’d have to do it without it seeing people you don’t intend to test with. You only get 5 tries. You can’t wait too long or it will hit the timeout. Sounds like a movie plot to me (I made a guess at one if you dig through my comment history).
- matthewmacleod 9y agoFor random faces, yes, but for a twin or sibling it’s more likely; what’s interesting is that they haven’t said how much more likely. If it were less than 1/50k then you might have expected them to confirm that it was still more secure than Touch ID, though that’s not certain.
- jv22222 9y agoCan someone help me understand why @gre got down-votes here? I don't get it. As far as I remember, in the big reveal, they did make a point of saying that faceid had a much lower chance of of colliding than the fingerprintid system.
- skiman10 9y agoHe got downvoted because he said something that didn't match up with what OP said. In the presentation, Apple said > The probability of a false match is different for twins and siblings that look like you So that means the 1 in a 1,000,000 chance doesn't make sense here because Apple said the probability is different in regards to twins and siblings that look like you. So @gre just spouted off the statistic when OP was asking what the probability might be in regards to twins and siblings, because Apple says that it is different.
- matthewmacleod 9y agoThey did, but the quote above was about confusion between twins or siblings. Those are explicitly not random people.
- __jal 9y agoI'm not the down-voters, but my guess is due to citing the 1-in-a-million figure, which is Apple's claim about a random false positive, in response to a question about false positives with twins. Someone reading fast or simply not thinking critically could come away with the wrong impression.
