Since 2005, the State of Oregon has been using facial recognition software on all DMV photos. The software won't work if you smile, so you are required to adopt a neutral expression. No word if you are required to adopt neutral hand gestures, because I've got a couple I'd like to use. Theoretically the reason for this is prevent meth heads from stealing IDs, of course one has to wonder why 1.8 million people's images (and ultimately everyone holding a driver's license or even an ID card in the state of Oregon) is necessary to be enrolled into the program. While theoretically the database is only for ODOT purposes, law enforcement has access to the system. Once this technology gets used in other states (and in federal jurisdictions), and I'm sure it has been already, it will be possible for a person's face to picked out of a crowd and matched against a digital database. Of course we are told this is all for our own security. I wonder. When I saw the police action on November 17, an amazing display of force, by the way, they had a poll camera taking pictures of the people. It seems to me not unreasonable to suspect that these images could be matched, at least in part, against the state's DMV database. I fully expect to see a system implemented in airports and other transportation terminals, maybe even on freeway overpasses, that will capture images of people and instantly match them to a DMV database, and it might even become a matter of suspicion, and grounds (legal or not, it doesn't matter) for inquiry if one's face does not trigger a match in the database. When you add in potential automated searches of Facebook, etc. for digital image recognition, the power of such an application becomes enormous. By the way, of course there's a corporate and lobbying link to all of this. Per the linked article above from salem-news.com: Note the "no bid" contract, typical of the security state. Also, when you go to, for example, the FBI biometric center, they talk about "privacy" rather than the right to be free unreasonable searches and seizures. Once the idea of "privacy" takes root, it becomes easy to blow off violations as a matter of excess prudishness of the governed. TSA is well known for this sort of rubbish.
