Earlier this week, Google introduced the Pixel 4 and Pixel 4 XL smartphones, which will go on sale later this month. But it seems that the biometric protection of new gadgets leaves much to be desired.
BBC journalist Chris Fox said that the Face Unlock unlock mechanism works even if the owner of the device has their eyes closed, which face recognition systems usually prohibit. The problem is that in this case, Face Unlock can be used by third parties, even when the owner of the smartphone is sleeping or is unconscious.

At the same time, Google developers were so confident in the reliability of Face Unlock that they removed other biometric mechanisms from the Pixel 4, such as a fingerprint scanner. That is, the new face recognition system is proposed as the only biometric authentication system available on the device.
Although the wound edition The verge reported that in Face Unlock settings there will be an option “Require eyes to be open”, now it is gone, and Google representatives already confirmed Fox says smartphones will go on sale without this security mechanism. Also, all references to this option have been removed from Face Unlock Support Pages, and now users are simply encouraged to keep their smartphones in a safe place.
Let me remind you that this is not the first time that researchers discover flaws in biometric authentication systems. For example, only this week, Samsung developers admitted that the fingerprint scanner in the Galaxy S10, S10 +, S10e and Note 10 smartphones may not work correctly due to the usual protective overlay on the screen. With the face recognition, the flagship Samsung is also not too good. So, in the spring of this year, it became known that the device can be fooled using ordinary photos or videos.
In addition, experts have already tricked the iPhone X with masks for $ 150; misled various Android smartphones using the headprinted on a 3D printer (same method worked and against Windows 10 protection). And according to the Dutch non-profit organization ConsumentenbondHaving tested 110 smartphones of various manufacturers, 42 devices from this list can be easily fooled by simply showing them a high-quality photo of the owner.
