Batman: The Dark Knight? (Score 1)

This seems oddly familiar to Batman: Dark Knight. Using cell phones to collect data points throughout a city to find the culprit (the Joker / toxic chemicals). Ultimately, in the movie, there were great concerns about privacy and use of the technology. The safety net here "Cell-All will operate only on an opt-in basis and will transmit data anonymously" seems nice on paper, but I'm sure those in a position to use it will feel the pressure to exploit the technology for more.
