iPhone 5S Touch ID fingerprint scanner fooled by Chaos Computer Club

The sticky-fingered don't need your fingers to get into your phone
iPhone 5S Touch ID fingerprint scanner

The iPhone 5S has been out for less than a week, but already Touch ID – its new fingerprint-scanning home button – has been duped into giving up its secrets.

A touch of bypass

So much for fingerprint scanners being the fuss-free future of smartphone security. Less than a week after the latest iPhone launchChaos Computer Club (CCC), a long-established organisation that deals with the security and privacy of new technology, has announced that it has managed to bypass the iPhone 5S' biometric security that lets you replace your passwords with your fingerprint.

One of the group, nicknamed Starbug, said "In reality, Apple's sensor has just a higher resolution compared to the sensors so far. So we only needed to ramp up the resolution of our fake."

What this translates to is that CCC used a well-established technique, but just took a better image of the fingerprint. The method involves finding a good fingerprint on a shiny surface (such as an iPhone screen), making it show up using powder, photographing it, printing it onto a transparency using a laser printer then converting that into a fake fingertip using nothing more advanced than wood glue.

A bit more involved than peering over your shoulder to memorise your PIN number, then – but it does demonstrate that the Touch ID isn't quite as secure as Apple claims it is.
