Prototype System Blocks Digital Cameras
lee1 writes "Researchers at the Georgia Institute of Technology have completed a prototype
device that can block digital
cameras. The team in the Interactive and Intelligent Computing division of
the Georgia Tech College of Computing used off-the-shelf equipment
(camera-mounted sensors, lighting equipment, a projector and a computer) to
scan for, find and neutralize digital cameras. The system works by looking for
the reflectivity and shape of the image sensors and saturating them with a
thin beam of visible white light.
The principal applications are expected to be protecting areas such as
government buildings and trade shows against clandestine photography, stopping
unauthorized amateur photography of, for example, shopping-mall Santas
(really!) and defeating video copying in theaters.
The countermeasure: film." Sounds perfect for copyrighted public spaces.
Does it just "block" the cameras, or does it destroy them?
Either way, I hope this comes in a personal unit. It'd be a nice way to avoid being photographed at family gatherings.

THERE IS ANOTHER SYSTEM
Nothing to see here, move along...
My other sig is funny.
It sounds like it's a technology for the power hungary.
And just what does the utility company in Budapest have to do with it?
Where does the school board find them and why do they keep sending them to ME?
when CCDs die.

Your scramble suit is ready.
no pictures allowed (we could never uncover conspiracies then).
If this gets into wide use, only criminals and terrorists will have pictures of Santa.
-
SLR Camera (that's acknowledged in the article) --- the sensor isn't revealed except during the actual taking of the picture, the rest of the time there's a mirror in the way.
-
Ordinary digicam, but use the optical viewfinder and keep your hand over the lens until you take the picture.
-
If they're using wavelength X for the detection process, just use a filter that blocks that wavelength and work in black and white (perfectly acceptable for most trade show spying)
-
Polarising filter will probably screw things up.
-
Lens Hood would mean the detection system would need to be on-axis.
-
Wear old CCDs as jewelery.
ianMore distracting than the unimaginative hollywood plot, hyperbolic acting, and unrealistic exploding cars/buildings/animated cats?
Come to think of it, that's the best anti-piracy technology to come out of Hollywood--the movies themselves.
Finally a countermeasure for those pesky speeding-ticket cameras that plague my city!!!! Down with the 60km/h (~37mph) limit!!!

Now I get it, it's $10 to get a photo of your kid frightened by Santa

but only if you're not taking the picture yourself...
"Caution: Do not look at movie theater screen with remaining eye."
You are not alone. This is not normal. None of this is normal.
Oh, everyone knows that. Just make a black laser and reverse the current from the power source.
There are no tiger attacks in my area and it's all because this rock I'm holding keeps the tigers away.
You know... the ones that used film... and you'd take it to a developer...
Kind of like how my Abacuss is protected from Spyware
In the industry, we call them "cigarette burns."

It kinda irritates me that there are no pictures of this thing

"...that gets good shots at 500+ metres. How do you deal with that?"
Simple - Aegis.
A couple years ago, movie theaters started offering a bounty for alerting them to bootleggers in the act. For the first time, I saw two security agents standing on either side of the movie screen - not so discreetly looking at the audience with their night vision/IR goggles.
So I decided I'd give them a show and told my Nokia to send all contacts via IR. I did it about every ten minutes and I knew it was getting security's attention. But I just didn't appreciate them watching me watch a movie. Kinda creepy, you know?
If it matters, the movie was Spiderman 1, and I haven't been watched since, but I just wanted to relay my little civil disobedience story.
And get my eyeballs burned to a crisp.
