This technology seems not too bad at first - "each person appears as a single pixel indistinguishable" - but after thinking about this, it's really a big deal for three reasons. First, it would be trivial to tie this in to the network of surveillance cameras, so you can see a person in detail when they walk past a camera. You're now not an anonymous pixel but HD video. Second, by correlating the "pixels" with even coarse celltower location over time, you should be able to match a cellphone with every person. In other words, you now know their identity and track almost everyone's location to within a foot. No GPS needed. Third, this information could be stored for all time and easily accessed. I think this really is a "game-changing" technology as far as privacy goes. It ties together location, identity, and images very tightly in a way they haven't been connected before.
