Reading two unrelated posts in the Times, thought about all the challenges we’ll have with Glass or other consumer Heads up Displays (HUDs) regarding privacy, theft and other related crimes.

If someone is at the ATM behind you with Google Glass, can hand gestures be recorded?   How about tones of lock combinations?  What about a glimpse of a physical key to a lock, record it, and printed to 3D printer?  Glass application to focus on the ‘targets’ eyeball, the HUD camera focuses, then locks onto the eye, captures, then performs a reverse projection onto a blank contact.  How about heat and/or UV imaging HUD lens views a smartphone, or touchscreen computer’s glass for finger prints for password breadcrumbs. The list goes on and on.

Future tech, partially, and not.
