Apple’s Craig Federighi offered new insights into Face ID in an interview with TechCrunch, and elaborated on how the feature will work aboard the iPhone X.
Software Engineering Chief Craig Federighi oversaw one of the most discussed gaffes from Apple’s September 12th event, where Apple’s new biometric security standard, Face ID, failed on stage.
Despite the wobbly that worried both critics and investors alike, Apple has remained bullish on the promise that Face ID will make Touch ID irrelevant forever – and in a recent interview with TechCrunch, Federighi had the chance to expand on just how the system will work.
Speaking to TechCrunch’s Matthew Panzarino, Federighi offered that Face ID was reliable and fast – explaining that the system works by identifying one’s eyes, nose, and mouth.
Naturally, instances where these facial features might be obscured – such as wearing a heavy balaclava or other gear – might render the feature unusable in which case users will have to make do with a PIN instead.
Clarifying the point, Federighi claimed that “If you’re a surgeon or someone who wears a garment that covers your face, it’s not going to work… but if you’re wearing a helmet or scarf it works quite well.”
One of Apple’s most promising claims is that Face ID will not only be able to track a user’s facial features despite changes over time (for example, beard growth or a haircut) but further that the feature will work around sunglasses or eyeglasses.
On the subject, Federighi has said that the polarization of one’s sunglasses shouldn’t affect Face ID – though consumers who favour sunglasses that block infrared will either need to take their glasses off entirely or rely on a PIN instead.
According to Federighi, Face ID will function when held at a similar distance to how one might take a picture with their iPhone’s front-facing camera. “Once your space from eyes to mouth come into view that would be the matching range – it can work at fairly extreme angles — if it’s down low because your phone is in your lap it can unlock it as long as it can see those features. Basically, If you’re using your phone across a natural series of angles it can unlock it”, Federighi says.
Speaking on privacy concerns, Face ID will reportedly function entirely on-device and will not transmit any data to the cloud for use by Apple nor third-party developers. Face ID scans are converted to a model housed within the Secure Enclave aboard the iPhone X, and scans cannot be remapped back to a face.
Similarly to Touch ID, Federighi claimed that Face ID would disable itself after five failed attempts. Further, the feature would be unavailable should an iPhone have not been used for 48 hours or if a user had not entered a passcode for 6.5 days and Face ID had not been used in the past four hours.
Face ID is set to debut on the iPhone X on the 22nd of September, and may arrive on other Apple devices in the not-so-distant future.
