Repression 2.0

The next step for governments struggling to keep up with the flow of dangerous data may be a technique called data mining. One possible model: the Total Information Awareness project, a post-9/11 U.S. Defense Department idea that, had it not been shut down by horrified lawmakers, would have analyzed patterns of writing, shopping, e-mailing and surfing among Web users. The notion wasn't to watch everything people said—it was to scan their online footprint for patterns that might point to criminals or terrorists. It's easy to imagine Beijing appropriating the concept when it can muster the computing power.

That would scare Web users for years. Technology has a way of constantly changing, but authoritarians of the world have at least one thing going for them: spreading fear is easy, and the Web makes it easier.
