Spy Satellites to ID You Via Your Shadow?
Why, spy satellites that can identify your shadow, of course!
Scientists are working on a system that will be able to analyze shadows from satellite video to recreate the way a person walks. Since your stride, sway, pace, and bounce combine to create a gait unique to you, gait analysis could prove to be a powerful tool for tracking criminals and terrorists (and you).
Of course, there are some caveats. Most satellites currently in orbit can't record high enough resolution images for effective gait analysis. Also, because the method is reliant on shadows, the system could be easily disrupted by rain or cloud cover and would prove completely useless at night.
Still, researchers believe this could prove to be an invaluable tool for tracking ne'er do wells. Oh, and you. [From: Daily Mail]
