Cloud-Powered (i.e., The Internet) Facial Recognition

By harnessing the vast wealth of publicly available cloud-based data, researchers are taking facial recognition technology to unprecedented levels

"I never forget a face," goes the Marx Brothers one-liner, "but in your case, I'll be glad to make an exception."

Unlike Groucho Marx, unfortunately, the cloud never forgets. That's the logic behind a new application developed by Carnegie Mellon University's Heinz College that's designed to take a photograph of a total stranger and, using the facial recognition software PittPatt, track down their real identity in a matter of minutes. Facial recognition isn't that new -- the rudimentary technology has been around since the late 1960s -- but this system is faster, more efficient, and more thorough than any other system ever used. Why? Because it's powered by the cloud.

The logic of the new application is based on a series of studies designed to test the integration between facial recognition technology and the wealth of data accessible in the cloud (by which we basically mean the Internet). Facial recognition's law enforcement uses -- to identify criminals out of a surveillance video tape, say -- have always been limited by the criminal databases available for reference. When Florida deployed Viisage facial recognition software in January 2001 to search for potential troublemakers and terrorists in attendance at Super Bowl XXXV, police in Tampa Bay were only able to extract useful information on 19 people with minor criminal records who already existed in any database they had access to. But the Internet was a much smaller place in 2001; Google was in its infancy, and the sheer volume of data available in a simple search simply didn't exist.

Often, the problems with facial recognition are rooted in the need for greater processing power, human and machine. After revelers rioted in the streets of Vancouver following the Canucks' defeat in the Stanley Cup, Vancouver police received nearly 1,600 hours of footage from bystanders furious with their fellow citizens; the department was woefully inequipped to handle the sudden influx of data, anticipating that it would take nearly two years to analyze all the information. Vancouver's Digital Multimedia Evidence Processing Lab was able to cut the processing time to a mere three weeks with a relatively small 20-workstation lab.

With Carnegie Mellon's cloud-centric new mobile app, the process of matching a casual snapshot with a person's online identity takes less than a minute.

Kinda scary on the one hand, a useful app for people like me who forget names too easily, on the other.
