Google Glass Knows Who You Are

Can Google Glass be hacked to include facial recognition? Of course:

At Philz Coffee in Palo Alto, Calif., a kid who looks like he should still be in high school is sitting across from me. He's wearing Google Glass. As I stare into the device's cyborg eye, I'm waiting for its tiny screen to light up.

Then, I wait for a signal that Google Glass has recognized my face.

It isn't supposed to do that, but Stephen Balaban has hacked it.

"Essentially what I am building is an alternative operating system that runs on Glass but is not controlled by Google," he said.

How long before wearing them becomes mandatory?
