Later on, the mother reregistered her face under different lighting, her son was no longer able to unlock her phone.
The Video shows the Mother locking the phone and then unlocking with her face, passes it to her son, Mark who is 10 year old, in less than a second, the phone actually does the same.
The important part is that when Face ID fails to recognise the user beyond a limited threshold, and the user immediately enters their password, that time the TrueDepth camera takes another photo to improves its reliability. The son was also able to unlock his father's phone, but only in one instance. However, she made a decision to further test things by registering all over again under indoor night-time lighting, similar to the first time.
Apple needs to address this situation because at the introduction, it says Face ID is more powerful than the Touch ID but the reverse might be the case!
While cases like this one might not be that common, it seems family members with similar facial structure could circumvent the privacy of their loved ones by fooling the Face ID tech. It was not for this goal that Apple designed and integrated this feature in their latest iPhone X, which is also the USP of this device apart from full screen display and other awesome features.
Attaullah Malik, the husband of Sherwani, pointed out some flaws in a LinkedIn post that led his son to unlock the iPhone X of his wife. As their distinct facial features may not have fully developed, so they might unlock your phone easily. Lets take a Look at the Mask! "Also, the additional neural network present in iPhone X that's trained to spot and resist spoofing doesn't work as intended in this scenario". "If you're concerned about this, we recommend using a passcode to authenticate". In the end, iPhone X recognized this face the owner of the mobile device. The Mask is being sold at $150!
Bkav's claims come despite Apple's statement that the engineering team had collaborated with "professional mask makers and make-up artists in Hollywood to protect against these attempts to beat Face ID".
