re: iPhone Fingerprint Hack Contest Dangles $18,000
There is a video today of someone supposedly "hacking" the Touch ID... but it's the same guy who registered his fingerprint that "unlocks" his iphone with something on his fingertip.
Even if you have thick chapped skin on your fingertips, the Touch ID will still recognize you because it reads your sub-dermal prints.
Of course he is going to unlock his own phone, because the Touch ID does not read the surface, but scans below the outer skin to recognize him as the owner.
We need to see another person who has NOT registered his fingerprints on this phone, using the registered person's printed fingerprint. But the guy who made this video obviously knew that wouldn't work. ;-))
Here is some information about the deep scanning that Touch ID does, and why printing a fingerprint, or using a severed finger will NOT work:
Capacitive -- A capacitive sensor is activated by the slight electrical charge running through your skin. We all have a small amount of electrical current running through our bodies, and capacitive technology utilizes that to sense touch. This is also the same technology used in the iPhone's touchscreen to detect input.
Radio frequency -- RF waves do not respond to the dead layer of skin on the outside of your finger -- the part that might be chapped or too dry to be read with much accuracy -- and instead reads only the living tissue underneath. This produces an extremely precise image of your print, and ensures that a severed finger is completely useless.
This video only proves that Touch ID can still recognize your fingerprint, even if you have something thin between you and the scanner.
This guy is not winning the contest, but nice try to fake things. ;-))
