(Dogs: the most obedient security guards)
When Face Unlock was first announced on the Galaxy Nexus, the Internet erupted over whether or not it was actually a worthy security feature. Does a security mechanism that can't differentiate between a picture of the user and the actual user's face go far enough to prevent would-be thieves? Perhaps not. So here at AndroidPIT we've tried to think of some other ways we might secure our phones (given unlimited resources and futuristic technology). Here they are:
Fingerprint technology has been around for a while. It's a fast, accurate and foolproof way of securing your Android phone. There are currently a number of fingerprint scanning apps out there but their results are quite dubious. A good fingerprint security method would come baked into your Android's hardware.
3D Facial Mapping
Face Unlock on Android 4.0 is great, but it doesn't go far enough. To break into a friend's smartphone, all you need is to hold a picture of them next to the camera (a recent update is supposed to track blinking but with varying success). 3D facial mapping would utilize two front facing cameras to map a three-dimensional photograph of themm thus spoiling the efforts of picture-holding thieves.
Voice recognition could also be used to unlock smartphones. In order to unlock your phone, you could have a special phrase like "banana phone."
(The Stunfone for iPhone is actually fake)
Perhaps the most effective way to keep would-be thieves out of your smartphone would be to install a small taser on the device that shocks unauthorized users (the phone would know they were unauthorized after they entered in a series of incorrect passwords or failed to match the owner's fingerprints). Downside? Accidentally shocking yourself.
Carbon Fiber Briefcase
If you really, really, REALLY don't want thieves messing around with your Android, you could always buy a titanium portable briefcase, like this Hermes briefcase, for carrying around your phone. At $16,000, it's quite the investment, but what's more valuable than your Android?
