Face ID Fooled Again; This Time by a Special 3D Printed Mask

Apple says it worked with Hollywood make up artists who have helped its engineers design Face ID so that it couldn’t be spoofed by photos or masks, but now a Vietnamese security firm claims to have successfully fooled the system using a facial mask.

Apple’s approach is more advanced and thus secure which is why the company boasts that Face ID is more secure than Touch ID. Proving Apple wrong are security experts from Bkav Corporation who managed to fool Face ID using a facial mask. The mask is crafted using 3D printing, 2D images, and “some special processing on the cheeks and around the face, where there are large skin areas, to fool AI of Face ID”.

“Special processing” has been applied to the cheeks and around the face to make the mask feel more lifelike. Bkav has shared a demonstration video seemingly showing an iPhone X being unlocked by both the mask and the person it’s based on.

While the hardware certainly has its limitations, it’s important to remember that Face ID relies heavily on machine learning and artificial intelligence to prevent spoofing. Theoretically, Apple could re-train Face ID’s neural network to protect from those kinds of attacks in the future.

Apple’s marketing boss Phil Schiller said during the iPhone X event:
Apple engineering teams have even gone and worked with professional mask makers and makeup artists in Hollywood to protect against these attempts to beat Face ID. These are actual masks used by the engineering team to train the neural network to protect against them in Face ID.
