A group of German hackers has found a way to bypass Apple's TouchID, and claims that fingerprint biometrics is an unsuitable method of access control.
The group, known as the Chaos Computer Club (CCC), demonstrated that a
fingerprint of the phone user, photographed from a glass surface, was enough
to create a fake finger that could unlock an iPhone 5s secured with TouchID.
The print was first photographed with 2400 dots per inch (dpi) resolution. The
resulting image was then cleaned up, inverted and laser printed with 1200
dpi onto a transparent sheet with a thick toner setting. Finally, pink latex
milk or white woodglue was smeared into the pattern created by the toner on
the transparent sheet.
