Which the machine won't recognise as a person (and will discard). It would take a human to track you but that's old school. Of course, that's only until gait recognition takes over from face recognition.

You'll stand out more to a human observer, but to a computer you'll be invisible.

Or you could just have really dark skin. That usually works just as well. (Example: http://www.gamespot.com/news/kinect-has-problems-recognizing...)

I'm guessing a reco fail raises flags -- so if you try to cheat the system, it just escalates than instance to an outsourced turk somewhere..
