One of the features that Google didn’t tout on stage with Android 4.1 Jelly Bean was a new feature for Android’s Face Unlock feature that makes it even more secure.
According to Droid-Life, Face Unlock has gained a feature called “Liveness Check” which might actually convince some Android users to start using the feature that arrived back with Android 4.0 Ice Cream Sandwich.
Liveness Check requires the user to blink before access is granted to the device when using Face Unlock to unlock the device. In Ice Cream Sandwich, the Face Unlock feature could be tricked using a photo of the person whose face is used to unlock the phone.
This new feature looks to squash that issue and make Face Unlock more secure.
Setting up Liveness Check is simple. Users who are running an Android 4.1 Jelly Bean only need to head into the device’s Security settings which can be found in the device’s main Settings.
Once there, users will want to choose Face Unlock as the method of unlocking the phone and after that process is completed, the device will ask whether or not to employ Liveness Check.
It’s certainly worth checking the box.
Unfortunately, most users won’t be able to take advantage of this feature in the near future. That’s because Android 4.1 Jelly Bean won’t start rolling out until July. And when it does, the first devices to get it will be the Samsung Galaxy Nexus HSPA+ and the Motorola Xoom tablet.
Manufacturers and carriers have yet to confirm the software for any other devices.
