We really hate it when someone tries to access our phone without permission. Reading messages, viewing photos and doing other things. Due to this, we add security to by adding a password.
Android 4.0 Ice Cream Sandwich offered us something different by launching the “Face Unlock.” It’s quite amazing. Just by putting your face in front of your camera, it would automatically unlock without having to ype a password. It’s great isn’t it? However, the Face Unlock offered by Android 4.0 also has some flaws. If your friend has this Face Unlock feature, it would be very easy to access his phone by simply tricking it. By placing a picture of that person in front of the camera, the phone also unlocks. Which makes it unsafe.
Android 4.1 Jelly Bean, the latest Android operating system made an upgrade to this face unlock. Now, simply getting your friends photo and putting in front of the camera no longer works. The upgrade for Face Unlock in Jelly Bean now has Liveness Check. In order to unlock your phone, you now have to blink. It’s amazing isn’t it? It really checks if you are really the owner by blinking.
Here’s how it works:
However, even with this new style of security, it is still advisable to use the old fashioned way of simply adding a long and not so easy to guess password to secure your information.
