As we upload more and more videos to the Internet—one hour of new video every second to YouTube alone—experts are finding new ways to mine them. A team led by Igor Curcio of Nokia's Research Center, for example, has developed an algorithm that stitches concertgoers' cellphone footage into a single, synchronized multi-angle film. The concept is relatively simple: the audio track serves as a guide to sync up the footage, and the software chooses the best shots.
DNA databases are highly protected resources, because they contain the most detailed fingerprint that can be used to identify a person — from genetic predisposition to cancer, to paternity tests, to criminal histories. But apparently RNA databases, derived from large genome studies, can also be used to pinpoint a person’s identity, according to a new study.
Diginfo brings us news of this Hitachi Kokusai system that can monitor video feeds from around the world in real time, scanning for a particular face. When it finds what it's looking for, it closes in to provide footage of what the person has been doing previously and what he or she is doing next.
What do you smartphone apps say about you? Not in the “who am I and what is my place in the world?” sense, but literally--what are your apps telling other people about you? Your location? Your identity? Your username and password? The Wall Street Journal has put online a pretty amazing, sometimes outraging, definitely interesting interactive graphic analyzing 101 popular iPhone and Android apps, telling you exactly what your apps are telling other people.
A somewhat strange story emerged yesterday involving an extremist antigovernment group, a North Dakota sheriff's office, and six missing cows, but there's a much larger story behind this brief legal tangle between local law enforcement and the Brossart family of Nelson Country. When Alex, Thomas and Jacob Brossart were arrested on their farm back in June after allegedly chasing the local Sheriff off their property with rifles, they became the first known U.S.
In Washington, D.C., where there are plenty of powerful people and precious places to protect, the cops have lots of high-tech tools at their disposal. But one tool, automatic license plate readers, could become much more than a crime-prevention device. D.C. police maintain the country's densest network of plate readers, and keep a three-year database of license plate locations — meaning they can track where everyone's car is, all the time, whether at the grocery store, an ammunition shop or Planned Parenthood.
DARPA’s latest tech challenge should make you hesitate to throw out your shredded documents, instead opting for the handy caveman solution of simply burning them. Until DARPA comes up with a way to read ashes as well as messages on shredded paper.
Worried about privacy on the Internet? It may be even worse than you thought — with rapidly improving face recognition technology, your automatically tagged Facebook pictures could help a stranger, or the authorities, quickly identify you on the street.
A Massachusetts man found himself trying to prove his identity this spring after a facial recognition system pegged his driver's license as a fake. The problem: He wasn't using a fake license. He merely looked like another driver.
A controversial piece of facial recognition technology (and a PopSci "Best of What's New 2010" alum) is rolling out in police stations across the country this fall, and naturally not everyone is happy about it.
