If you feel the need to add extra security measures for your Android device then you might want to consider looking at the the new Visidon Applock. The app features a new way of protecting your phone by giving it cool facial recognition features.

You need only to snap a photo of your face using your front facing camera and select the apps you want to protect. The apps you pick will require facial recognition once someone opens it again.

Given that I haven’t tried it myself, it sure is a question of how reliable the app’s technology is. Another concern is whether the technology is secure or not but then again, I don’t see how you need to go as far as needing a “virtual vault” for your Android smartphone.
