New Delhi: In less than a fortnight of conducting the first experiment, a team of Vietnamese researchers claims to have again fooled Apple`s Face ID authentication system in the super-premium iPhone X, using a composite 3D-printed mask.
In the new experiment, the team at Vietnamese security firm Bkav used a 3D mask costing $200. The mask is made of stone powder, with glued 2D images of the eyes.
This new mask has been named "the artificial twin", since the research has shown that the way an iPhone X unlocked by the mask is similar to by twins.
Bkav experts found out that stone powder can replace paper tape to trick Face ID' AI at higher scores. The eyes are printed infrared images – the same technology that Face ID itself uses to detect facial image.
The experiment contradicts Apple Senior Vice President Phil Schiller's claim that Face ID can distinguish real human face from masks, thanks to its artificial intelligence (AI).
The Bkav security experts who also posted a video on how they did this said Face ID can be fooled by mask, which means it is not an effective security measure.
In 2008, Bkav was the first company in the world to show that face recognition was not an effective security measure for laptops when Toshiba, Lenovo and Asus used this technology for their products.
Face ID projects more than 30,000 invisible IR dots and claims to only unlocks iPhone X when customers look at it and is designed to prevent spoofing by photos or masks.
Apple`s Face ID technology uses a TrueDepth camera system made up of a dot projector, infrared camera and flood illuminator, and is powered by A11 Bionic to accurately map and recognise a face.
According to the firm, Collecting a fingerprint is much harder than taking photos from a distance.
