The Government Is Trying to Wrap Its Mind Around Yours

Imagine a world of streets lined with video cameras that alert authorities to any suspicious activity. A world where police officers can read the minds of potential criminals and arrest them before they commit any crimes. A world in which a suspect who lies under questioning gets nabbed immediately because his brain has given him away.

Though that may sound a lot like the plot of the 2002 movie "Minority Report," starring Tom Cruise and based on a Philip K. Dick novel, I'm not talking about science fiction here; it turns out we're not so far away from that world. But does it sound like a very safe place, or a very scary one?

It's a question I think we should be asking as the federal government invests millions of dollars in emerging technology aimed at detecting and decoding brain activity. And though government funding focuses on military uses for these new gizmos, they can and do end up in the hands of civilian law enforcement and in commercial applications. As spending continues and neurotechnology advances, that imagined world is no longer the stuff of science fiction or futuristic movies, and we postpone at our peril confronting the ethical and legal dilemmas it poses for a society that values not just personal safety but civil liberty as well.

Consider Cernium Corp.'s "Perceptrak" video surveillance and monitoring system, recently installed by Johns Hopkins University, among others. This technology grew out of a project funded by the Defense Advanced Research Projects Agency -- the central research and development organization for the Department of Defense -- to develop intelligent video analytics systems. Unlike simple video cameras monitored by security guards, Perceptrak integrates video cameras with an intelligent computer video.
