The new Google Pixel 4 smartphone comes with a Face Unlock feature, it has now been discovered that the feature works even when you have your eyes closed.
This could raise some privacy concerns as someone could be able to unlock your device using Face Unlock whilst you are sleeping. Have a look at the video from Chris Foxx from the BBC below that shows this in action.

Privacy Concerns and Implications
As we can see from the video, this is definitely something that could be a privacy issue. The Face Unlock feature on the Google Pixel 4 is not just used for unlocking the phone; it is also utilized for payments and app sign-ins. This means that if someone gains access to your phone while you are asleep, they could potentially make unauthorized purchases or access sensitive information stored in various apps.
The fact that the Face Unlock works with eyes closed is particularly concerning because it undermines the security that biometric authentication is supposed to provide. Typically, biometric systems like Apple’s Face ID require the user to have their eyes open, adding an extra layer of security. The Pixel 4’s current implementation could be seen as a step backward in terms of user privacy and security.
Google’s Response and Future Updates
As yet, there does not appear to be any official comment from Google on this issue. However, it is worth noting that Google has a history of responding to user concerns and rolling out updates to address security flaws. For instance, when the Pixel 3 had issues with its camera app, Google quickly released a software update to fix the problem.
Given the significant privacy implications, it is likely that Google will address this issue in a future software update. They could potentially add an option to require eyes to be open for Face Unlock to work, similar to how other biometric systems operate. Until then, users concerned about this vulnerability might want to consider using an alternative unlocking method, such as a PIN or password.
Comparisons with Other Biometric Systems
To put this issue into perspective, it’s helpful to compare the Pixel 4’s Face Unlock with other biometric systems. Apple’s Face ID, for example, requires the user to have their eyes open and be actively looking at the device. This makes it much harder for someone to unlock the phone without the owner’s consent. Similarly, many Android devices that use fingerprint sensors require the user to be conscious and actively place their finger on the sensor.
The Pixel 4’s Face Unlock system, while convenient, seems to prioritize ease of use over security. This could be a deliberate design choice by Google to make the unlocking process as seamless as possible. However, it does raise questions about the balance between convenience and security, especially in a world where smartphones are used for increasingly sensitive tasks.
What Users Can Do
In the meantime, there are steps that users can take to mitigate the risk. One option is to disable Face Unlock and use a more secure method like a PIN, password, or pattern. Users can also enable two-factor authentication for apps and services that support it, adding an extra layer of security.
Another potential solution is to use a third-party app that offers additional security features. For example, some apps can lock specific applications or functions, requiring a separate authentication step to access them. This can provide an extra layer of protection for sensitive information.
As soon as we get some more details, we will let you guys know.
