first_imgThe rumors of a fingerprint scanner in the new iPhone have been circulating for months, and at least this time, the rumors were right. The Touch ID sensor is one of the headlining features of the top-of-the-line iPhone 5S. Biometric security measures have the appeal of being easy to use, but a password is something you can keep to yourself, whereas a fingerprint is something you leave all over the place. It was only a matter of time before someone figured out a way to beat the Touch ID sensor, but it’s surprising it happened this fast. The Chaos Computer Club (CCC) claims to have defeated the iPhone’s fingerprint scanner in only a few days.According to the CCC, the hack was accomplished with standard household items. In fact, it links to a 9-year-old how-to on recovering and copying fingerprints from surfaces that details the process used. It all starts with finding the target print. It can be visualized on a surface with superglue or graphite powder — dusting for prints, basically. Then it needs to be captured in a digital image or scanned at about 2400dpi, which is high, but within the realm of a high-end consumer camera. So now you have captured the target’s print, but things get a bit more complicated from there.The digital version of the print is probably imperfect, so some Photoshop work might be needed to clean up any debris or troublesome wrinkles in the ridges. This tweaked image should be a close enough approximation to fool most scanners. The next step involves printing the image onto a clear plastic sheet or transparency slide using a standard laser printer with a heavy toner setting. This produces a negative mold of the finger, which can be coated with wood glue or any number of resins to create a flexible copy of the original print.There is a video that seems to show such a dummy print being used to unlock an iPhone 5S. This appears legit at first glance, but there could be something sketchy going on. For example, the second finger using the casting could actually be enrolled in Touch ID as well.Apple really talked up the Touch ID sensor as a marvel of security that would know the difference between a real finger and a lump of inorganic matter. It supposedly uses capacitive technology to scan and identify fingerprints, but maybe a thin layer of glue with a warm human digit underneath is close enough.last_img
