Prism Skylabs CCTV Deletes People From Busy Cities... For A Reason

This CCTV System Deletes Humans From Cities

A new form of CCTV is able to turn a bustling city into a 'ghost town', in order to protect your privacy.

The system, as reported by New Scientist, is able to paint over humans and vehicles in live video.

While it might seem counter-intuitive (surely CCTV is for… watching people?) the idea actually makes a lot of sense. The aim is to allow in-store cameras to monitor how customers navigate stores, and build up an aggregate range of data to improve shops, stock and other elements of the retail environment, without transmitting pictures of their movements over the web.

Prism Skylabs' system is able to carry out that analysis itself while painting over the live video. You could also use it in the home - leaving cameras on all the time, but only having them record images of people when you're out.

Head over to New Scientist for more details and an interview with the company behind it.

9 Gadgets To Help You Avoid Surveillance

The Japanese government counter-terrorism practice of fingerprinting foreigners who enter the country may have inspired Doctor Tsutomu Matsumoto to invent "fingerprinting gels", a way of faking fingerprints for scanners.Learn how to make your own here. (credit:AP)

Worried someone around you is secretly recording everything you do? No fear! There's a relatively low-tech way to defeat such snoops, via white-noise-producing audio jammers. These tiny devices use good ol' white noise to blur the sound picked up by hidden microphones and other surreptitious recording devices. (credit:Flickr: Anonymous9000)
Phonekerchief(03 of09)

MIT's Technology Review calls it the newest, hottest Thanksgiving accessory -- but you can use phone-size "Faraday cages" like this (sold by uncommongoods) to block your cellphone's call signal, WiFi and GPS. Handy now that federal courts are ruling that cops can track suspects via cellphone sans warrant, and Apple can remotely disable your phone camera with a click. As security researcher Jacob Appelbaum said in an interview with N+1 back in April, "Cell phones are tracking devices that make phone calls." So shouldn't you be prepared for when you don't want to be tracked? (credit:uncommongoods)

Hidden cameras got you down? Blind them all with a simple baseball cap lined with infrared LEDs. Amie, a hacker on WonderHowTo, shows the world how to make one, while this German art exhibition lays out how these ingenious devices work. (credit:AP)

These receivers reveal the telltale electronic crackle of hidden mics and cameras. Strangely enough, they were around long before "surveillance culture" became a common phrase. Today they're sold in all sorts of shops for surveillance paranoids. (credit:Gadget Playground)
Camera Map(06 of09)

Sometimes hiding your face isn't enough; sometimes you don't want to be seen at all. For those days, there's camera maps. The NYC Surveillance Camera Project is currently working to document the location of and working status of every security camera in New York City. This project has been replicated by others in Boston, Chicago and Bloomington, Indiana. Notbored.org has even published a guide to making your own surveillance camera maps (here). (credit:AP)

Credit to artist Adam Harvey for this one. Inspired by the "dazzle camouflage" used on submarines and warships during World War I, he designed a series of face paint principles meant to fool the facial recognition schemas of security cameras.

Walmart may be the premier symbol of corporate America, but its disposable cellphone selection can help you start a thoroughly maverick lifestyle. $10 TracFones work on most major networks, including AT&T, T-Mobile, Sprint and Verizon, and come with minutes prepaid so you can dispose of the devices when you're done.

RFID-Blocking Wallet(09 of09)

Radio-Frequency Identification (RFID) chips are now regularly implanted in passports, ID cards, credit cards and travel papers. These tiny chips make machine-reading your documents easier -- but could also let anyone with the right type of scanner scrape your information and track your whereabouts. Luckily, gadget geeks have come to the rescue again, this time with RFID-blocking wallets. Working on the same principle as the "phonekerchief", these wallets create a Faraday cage around your items, keeping their data secure until you take them out to be scanned where they're supposed to be scanned. Destroying the chip is simpler: just nuke it in the microwave for five seconds. Of course, whatever you're microwaving might burst into flames first... (credit:AP)
