Face ID is Apple's replacement for Touch ID on the iPhone X. Instead of scanning your fingerprint it scans your face to unlock your iPhone and authenticate purchases. It might not be a question of movie-like authenticity, however - security researchers at Bkav claim to have thwarted Face ID by using a specially-built mask. Face ID is different from other electronic devices' image recognition techniques due to this dot projection, which creates a 3D image by directing beams of infrared light at a person's face; then, artificial intelligence essentially "learns" the face and keeps other faces from accessing the phone.
The firm says it was able to trick Apple's Face ID AI by understanding how it worked.
In the video, Bkav explains how the life-size mask is made from a combination of 2D and 3D printing, plus makeup and silicon for raised areas like the nose.
The researchers had an artist make the silicone nose for the mask by hand.
Schwartz (euroinfosec) • November 13, 2017 Researchers at security firm Bkav assembled a 3D mask to trick Face ID on the iPhone X. Face ID is not very reliable because it is not very strict and relies too much on AI, claims Bkav.
As outlined in Apple's white paper, Face ID uses a TrueDepth camera system to accurately map the geometry of a face and recognise it.
Vietnamese firm "Bkav" claims it took less than a week and a mere US$150 to outsmart the supposedly sophisticated AI technology, which Apple Senior Vice President Phil Schiller said had been perfected by the company's engineering team.
'With Face ID's being beaten by our mask, FBI, CIA, country leaders, leaders of major corporations, ect. are the ones that need to know about the issue, because their devices are worth illegal unlock attempts. The fact that Face ID can be fooled shows that biometric methods don't offer foolproof security.
The researchers also think that their technique would require a detailed measurement or digital scan of the face of the target iPhone's owner.
The iPhone X has been a little bit of a let down for some users who saved up big and waited in line long for Apple's latest smartphone. The researchers suggest that Face ID's weaknesses mean it should not be used by CEOs or presidents, for instance.
But even if that's true (and we're not certain the clip is to be trusted 100 percent), Bkav's expertise is far from widely available.
