Schneier: The Future of Privacy

In an article which was originally published in the Minneapolis Star-Tribune, Bruce Schneier thoughtfully writes that:

Most people think of surveillance in terms of police procedure: Follow that car, watch that person, listen in on his phone conversations. This kind of surveillance still occurs. But today's surveillance is more like the NSA's model, recently turned against Americans: Eavesdrop on every phone call, listening for certain keywords. It's still surveillance, but it's wholesale surveillance.

Wholesale surveillance is a whole new world. It's not "follow that car," it's "follow every car." The National Security Agency can eavesdrop on every phone call, looking for patterns of communication or keywords that might indicate a conversation between terrorists. Many airports collect the license plates of every car in their parking lots, and can use that database to locate suspicious or abandoned cars. Several cities have stationary or car-mounted license-plate scanners that keep records of every car that passes, and save that data for later analysis.
