iPhone X Face ID at Apple event

Just how reliable will Face ID be, the new facial recognition system built into Apple's new iPhone X handset? It may need a bit of fine tuning, if its debut at today's big Apple event is anything to go by.

Just how reliable will Face ID be, the new facial recognition system built into Apple's new iPhone X handset? It may need a bit of fine tuning, if its debut at today's big Apple event is anything to go by.

Being demoed onstage by Craig Federighi, Apple's senior vice president of Software Engineering, Face ID seemed to have trouble recognising the executive in order to unlock the samsung parts .

You can see the shaky moment in action at the re-run page for the event's livestream. It kicks in at just after the 1 hour, 35 minute and 30 seconds point.

New tech, new creases to iron?

The Face ID system uses the iPhone X's TrueDepth camera in order to ensure only the correct user gets access to the phone's innards. And it's a multi-tiered system that should let it work seamlessly and safely, according to Apple.

A dot projector is used to build an accurate map of the shape of your face in 3D, with 30,000 invisible dots pinpointing the curves of your head and features. An infrared camera then reads that pattern and captures an infrared image, using the two data sets to confirm a match on the software side. There's also a Flood Illuminator that uses infrared light to help identify users in the dark.

Was one of these elements struggling on stage? While the Face ID system did eventually pick up Federighi's features (after a second attempt), it wasn't the perfect demonstration Apple would have hoped for. And, according to our man on the ground Gareth Beavis in his hands on: iPhone X review, it was problematic at the post-event demo area too.

However, some people are pointing out that the iPhone X may have been restarted, so it was asking for a PIN, which is a security feature after an iPhone has just been restarted.

Facial recognition has had a bad rap in security circles previously, having been easy to hack, while the removal of Touch ID in the iPhone X makes Face ID's accuracy of the upmost importance.

With the nexus 6 screen replacement shipping to customers this November, Apple has a few weeks yet to fine-tune the system. There's a very good chance that this is far from final software at this early stage, meaning Apple could have perfected the system by the time it reaches consumers.

Security in an increasingly-connected world is a growing concern, even among the casual tech fan and, in many ways Apple has set elevated standards for itself by developing the ever-reliable Touch ID fingerprint scanner. Here's hoping it irons out the Face ID creases, so that it can identify the ones in our furrowed brows.
