Criminals tempted to return to the scene of the crime might find themselves rethinking that impulse if the Questionable Observer Detector is embraced by police forces. The QuOD scans video of a crime scene, searching for those in all-too-frequent attendance, hoping that those repeat gawkers might in fact know something about the crime itself.
The QuOD, as it's called, comes from the Department of Computer Science and Engineering at the University of Notre Dame, is essentially 3-D facial recognition software. It creates "face tracks," some kind of recognizable pattern in a face, to pick individual people out of a crowd. The interesting part is that it works from any video stream, a big bonus in a world where our first impulse at seeing a crime is to whip out our smartphones and document it on video.
That means that the QuOD is useful for picking out those who show up at crime scenes repeatedly, but also at picking out faces in areas documented with multiple security cameras or personal video recordings. The software counts the number of times a particular face pops up, and if it's more than a certain amount (set by the operating authorities), it'll present that person as a possible person of interest--though it doesn't seem to link to any database, like this FBI face detector does.
Luckily, that's all it does--there's no Minority Report-style motive assessment. It's simply a shorthand for a formerly tedious and arduous task, that of scanning through footage to try to find any recognizable faces. The QuOD hasn't as yet been picked up for use by any police force, but we could see it being a useful timesaver.

Something about this makes me nervous.
@JohnnyH you have nothing to feel nervous about unless you did something wrong. I really never understood why people complain so much about all these privacy issues. When I was a child there were no such things as camera on every corner. Now there are. Has anything in my life changed becuase of it. nope. In 30 years so called privacy has changed DRASTICALLY. so many more of our actions are tracked now. my life has not been impacted one TINY bit. why complain unless you have are going to get in trouble for something you shouldn't be doing.
@inaka_rob
Privacy and criminality are not related.
We complain because we're not like you. By all means, if you chose to live in an invasive environment and it doesn't bother you, go for it. it's your life. but do not force me to life in some orwellian nightmare for your convenience.
Some of us are born protective of our private lives, and some of us know history very well. System's WILL be abused.
Privacy is essential to person's well-being.
Why should anyone expect privacy in a public area? Get over it. Behave and you'll be fine.
Agreed, if you aren't doing anything wrong then get over it. If not only for the deterrent factor, then at least for the fact everyone would benefit from this if they or someone close to them was the victim...
All to many complaints until someone you know gets hurt. Then what, complain there wasn't anything in place to catch the suspect in time?
Stop complaining about well thought out ideas that have been in the making for years. If you're worried about being seen in the background entering a porn shop 3 times then trust me, there are bigger issues at hand than your embarrassment level.
I love that line " if you're not doing anything wrong ..."
The (almost bankrupt) state of Illinois halted death penalties after DNA tests proved that there were a large number of innocent folks in line. From that one would assune that THEY weren't doing anything wrong...
Sure this stuff can hurt you. If there's some kind a crime spree happening and you get identified with it, the media coverage can make a big dent in your life. Never mind that you're ultimately tossed aside. Those kinds of things can stick.
And how about if it comes about because of this fabulous facial recognition software. Last I heard that stuff was notoriously unreliable. It could not only be fooled, it sometimes just went way out in left field.
Not to mention, I don't want to envision a world where my whereabouts are known 24/7. The question "what are you doing here?" really only has one answer "none of your business." Unfortunately, that's becoming unacceptable.
Well I see you live your life in fear.
While you're sitting inside with the blinds closed this technology is getting better because of it's use and because people like you (thank god) aren't calling the shots by not allowing progress.
this is not tracking technology, they take film from tv crews and anyhting like "our smartphones " that postes them on youtube, the invasion of privacy starts there, its allready being broadcasted by someone else, they just use it, and according to the law, you have no expectation of privacy in public areas, like streets in a city, where you would see most of these images being taken from, and this is not for testifiable evidence any half decent lawyer could get it thrown out this is just to find suspects, a first stepping stone if you will, then they investigate you and find evidence then prosecute, not prosecute because of this tech. Just helping weed out the good guys from the bad. Simple people, relax please.
