Two weeks ago, the B&B took the time to educate me about license plate readers and their various extra-legal uses. As someone who has worked at least part-time in the tech industry since the mid-90s, I started thinking about what the cost would be of a distributed plate-tracking business. Eventually the readers will be smaller and less obvious, at which point you throw a couple of bucks to Uber drivers and the like to toss them on all four corners and send you the data.
Given enough sources, eventually you’d be able to have a pretty good database of personal movement in your chosen area. That data is certainly worth money to someone, whether that “someone” is a real-estate developer, a fast-food franchisor or a private detective. Short of writing legislation specifically to stop such activity, I don’t see how anybody’s going to stop that business model from eventually becoming a reality.
In the meantime, however, there’s already one entity that has access to a nontrivial database of ANPR information. Good news! At least one government official has proposed that this information be used to save you from yourself.
