I'm not sure that is accurate... "As an example, he demonstrated how he could use his fake fingerprint to unlock his iPhone — that features a ‘Touch ID’ fingerprint sensor integrated into its home button." http://www.iphonehacks.com/2014/12/hackers-reproduce-fingerprints-german-defense-minister-public-photos.html http://www.iphonehacks.com/2014/12/hackers-reproduce-fingerp... It isn't entirely clear which fake fingerprint was used. I guess we should probably watch the CCC talk.

    Hehe well obviously not hers. What I meant was that it wasn't clear how he built the fake fingerprint he tested, whether he used the exact same method he used to construct the defense minister's fingerprint, or whether he "cheated" to make it easier on himself.

      Ah haha, sorry, I misunderstood you. Yes, definitively the details of this are fundamental to know if this could work in non-ideal conditions -it's not the same to take a high res photo only of your finger with good lighting than use publicly available, normal photos.

        Agreed, you worded it much more clearly than I did :)

The only fun thing here is that he pulled them off a photo. The Myth Busters guys did this a long while back with dusted prints .... https://www.youtube.com/watch?v=3Hji3kp_i9k https://www.youtube.com/watch?v=3Hji3kp_i9k Of course, things may have gotten better or worse since then.
