Eye-scanning technology, voice-print security, palm prints: Biometric security has almost become one of the basic signifers of existing in the future, like clean white walls and rounded surfaces. In Minority Report the biometrics extended to the point that Tom Cruise’s character, John Anderton, was easily identified by animated advertisements as he walked through a mall, and later on he had to actually replace his own eyeballs so he could avoid detection.
Ickiness aside, biometrics have become less futuristic and more now-istic. The entire town of León, in central Mexico, contracted with Global Rainmakers, Inc., to install iris scanning technology throughout the town. Locals will be able to use iris scanning to get on the bus, use ATMs, and get hospital care.
But the people of Leon might want to consider a report (free with registration) from the National Research Council before they go too far down that road, because there are some significant problems with going all biometric, all the time.
It’s not much of a spoiler to say the aliens in District 9 have the snazziest trigger lock around. The Prawns, as they are known in the movie, have some strange ideas for safety, though. Their trigger lock is DNA-encoded not to keep little Prawns away from dangerous gear, but to prevent any other species from activating the weapons. (That’s the sort of detail that raises all sorts of questions about just who the Prawns were fighting that they needed this kind of security, and whether the enemy also had DNA-locked rifles.)
While the Prawns seem to have mastered DNA-detecting technology, it remains a bit beyond our reach out here in the real, human world. But that may be the next big frontier in biometrics. Because, let’s face it, the typical kinds of biometric security used in of the lairs of movie super-villains isn’t science-fiction anymore—it’s reality.
Fingerprint scan? We can do that on a laptop, or even a mere thumb drive. Palm scan? Pssh. Placing a hand on the scanner is passé. Retinal scan? Of course. Facial recognition? Voice recognition? Done and done. All of these different biometrics has been exploited by security companies trying to make money in a world where verifying authenticity is becoming an increasing problem. But the biological signature big business and national governments really want to capture is DNA. Unlike our faces and voices, it never changes. Unlike our fingerprints, it’s very difficult to fake. And except for identical twins, it’s totally unique to each individual (and it may soon be possible to distinguish even identical twins [pdf]). Because this technology would be so valuable, everyone from the Austrian national government to major corporations is toiling away (pdf) in their R&D departments to develop a DNA biometric lock.
