Recently, Google introduced its new flagship Pixel 4, and now it has already revealed serious problems.
Problems with the Pixel 4
Google has already confirmed issuessecurity of the facial authentication system in the new Pixel 4, recognizing that the technology allows you to unlock the device even when the user's eyes are closed.
The first reviews of the Pixel 4 were mostlypositive. Many praised the phone for its ultrafast new face unlock system, which replaces the fingerprint scanner and works almost the same as the Apple Face ID on the iPhone. However, the BBC found that the Pixel 4 can be unlocked by the face of the user, even if he is sleeping (or pretending to be sleeping). This is noticeably different from the Apple Face ID system, which requires the user's eyes to be open to unlock the iPhone. Although iPhone users can turn off this attention feature for convenience, it’s always on by default. In Pixel 4, it is completely absent.
By the way, Google, however, does not hide this fact. The Google support page states: “Your phone can also be unlocked by someone else if it is held up to your face, even if your eyes are closed. Keep your phone in a safe place, such as in your front pocket or purse. ”
To “prepare for unsafe situations,”Google recommends holding the power button for a few seconds and pressing “Lock”, which disables notifications and unlocks face recognition.
In the early leaks, the Pixel 4 in the screenshots wasthe “require eyes open” setting to unlock the face is shown. It is possible that Google tried to implement a function similar to Apple Attention Aware, but did not modify it at the time of launch.
Speaking at the presentation of Google Pixel 4, ManagerOn Pixel products, Sherry Lin said: “In fact, there are only two face-to-face [authorization] solutions that match the super-security bar. So, you know, for payments this level is ours and Apple. ”
Cybersecurity experts disagree withgiven statement. “If someone can unlock your phone while you sleep, this is a big security issue,” security blogger Graham Cluley told the BBC. In a statement sent to the BBC, Google said it would "continue to improve Face Unlock over time."
