Trashnet - Garbage Trucks with License Plate Readers

CA - San Jose may enlist garbage trucks as eyes on the ground for a short-staffed police force.

Equipping trash haulers with license plate readers would turn them into roving scouts for the San Jose Police Department. Already, the trucks travel every city street every single week, covering more ground than a cop car.

Mayor Sam Liccardo proposed the idea with support from council members Raul Peralez—a former policeman—and Johnny Khamis. more

A Win for Whistleblowers - Ag-Gag Law Gagged

The U.S. District Court for the District of Idaho struck down Idaho’s “ag-gag” law, which criminalized undercover investigations in which animal cruelty was filmed and publicized.

A coalition of animal right groups and activists challenged the law, and the Reporters Committee led a coalition of sixteen news organizations in filing an amicus brief in December, arguing that the law infringed on constitutionally protected newsgathering rights.

The law, Idaho Code § 18-7042, created the new criminal felony offense of “interference with agricultural production,” which occurs when a person, among other things, entered an agricultural production facility by misrepresentation and made audio or video recordings of the facility’s operations. It was enacted in early 2014 after animal rights activists aired videos of workers using a tractor to drag cows with chains around their necks, while also beating and kicking them.

Chief Judge B. Lynn Winmill condemned the law as an unconstitutional ban on valuable political speech on food and worker safety, which are matters of public concern.

“§18-7042 seeks to limit and punish those who speak out on topics relating to the agricultural industry, striking at the heart of important First Amendment values,” the opinion states. “The effect of the statute will be to suppress speech by undercover investigators and whistleblowers concerning topics of great public importance: the safety of the public food supply, the safety of agricultural workers, the treatment and health of farm animals, and the impact of business activities on the environment.” more

New Ultra Low Light Level Camera for Investigators... named Amos Burke

Ever been poking around in low-light with your camera and thought, "you know what, I could really do with an extra few million ISO"? To be honest, neither have we because such a light-sensitivity would be ludicrous for most users.

Well, that hasn't stopped the folks at Canon stepping things up in a big way with its full-frame ME20F-SH, a 4,000,000 ISO HD video camera that seems sure to bring the noise.

The seeds were sewn for Canon's new shooter in 2013, when the company announced the development of a new 35 mm full-frame CMOS sensor specifically for filming in poorly lit environments. This sensor has now found its way into a cubed-shaped 4 x 4.5 x 4.4 in (10.2 x 11.4 x 11.2 cm) body that weighs approximately 2.4 lb (1.1 kg) and features an EF mount for compatibility with the Canon's interchangeable EF glass...

The result is, Canon says in lieu of sample footage, the capture of low-noise, color, Full-HD video of subjects with a minimum illumination of less than 0.0005 lux. For reference, a crescent moon is about 0.3 lux. Infrared illumination has made it possible to capture such dim environments previously, but only in black and white. more

FutureWatch - The Dark Art of Light Eavesdropping is Coming

Maite Brandt-Pearce, a professor in the Charles L. Brown Department of Electrical and Computer Engineering, and Mohammad Noshad, now a postdoctoral fellow in the Electrical Engineering Department at Harvard University, have devised a way of using light waves from light-emitting diode fixtures to carry signals to wireless devices at 300 megabits per second from each light. It’s like having a whole wi-fi system all to yourself; using light waves, there would be more network access points than with radio waves, so less sharing of the wireless network...

Their breakthrough means that data can be transmitted faster with light waves using no more energy than is already required to run the lights....

“You can use it any place that has lighting,” Brandt-Pearce said. “In a stadium, in a parking lot, or from vehicle to vehicle if using LED headlights and taillights.”

Like current wireless communications, encryption is necessary to keep data secure, but Brandt-Pearce noted that a secure network could be created in a room with no windows.

“It can’t be detected outside the room because the light waves stop when they hit something opaque, such as a wall,” she said. “That can keep communications secure from room to room.” (Generally speaking. However, a hair-like strand of fiber optic poking into the fixture from above the false ceiling should do the trick.)

And two separate networks in different rooms would not interfere with each other the way they do with present wi-fi networks.

She said devices with LED circuits in them can also communicate with each other. more more

Modulation of room lights for eavesdropping purposes is not new. The advent of ubiquitous LED lighting, however, will dramatically increase the effectiveness and ease of this tactic for eavesdropping... and the long-range wireless interception of computer data via optical means (even if it is encrypted).

Yet More Invisibility Eyeglasses

This year, AVG will reveal a set of concept invisibility glasses at Pepcom in Barcelona before Mobile World Congress. 

What are invisibility glasses?

Developed by AVG Innovation Labs, the glasses help protect your visual identity in the digital age.

Through a mixture of technology and specialist materials, privacy wearables such as invisibility glasses can make it difficult for cameras or other facial recognition technologies to get a clear view of your identity.

...there are generally two different methods of combating unwanted facial recognition:

Infrared Light
The idea is to place infrared LEDs inserted around the eyes and the nose areas. Since the infrared lights are completely invisible to human eyes, they are only detectable by cameras which are sensitive to the wavelengths of these LEDs. They claim to break face detection when the lights are on.

In this example we show how infrared can be used to avoid Facebook’s facial recognition technology.

Retro-reflective Materials
These specialist materials help maintain your privacy at the moment that the image is actually taken.

PS - This is a proof-of-concept project. Not for sale. However, you can make your own.
Other glasses.

Note: Many cell phone cameras have infrared cutoff filters built into their lenses... and you can bet law enforcement facial recognition systems do too.

Build Your Own Invisiability Device for Under $150

Researchers at the University of Rochester create a 3-D, transmitting, continuously multidirectional cloaking device. ... and they say you can too!
(more)
(more)
To build your own Rochester Cloak, follow these simple steps:
lens diagram
For their demonstration cloak, the researchers used 50mm achromatic doublets with focal lengths f1 = 200mm and f2 = 75mm
  1. Purchase 2 sets of 2 lenses with different focal lengths f1 and f2 (4 lenses total, 2 with f1 focal length, and 2 with f2 focal length)
  2. Separate the first 2 lenses by the sum of their focal lengths (So f1 lens is the first lens, f2 is the 2nd lens, and they are separated by t1= f1+ f2).
  3. Do the same in Step 2 for the other two lenses.
  4. Separate the two sets by t2=2 f2 (f1+ f2) / (f1 f2) apart, so that the two f2 lenses are t2 apart.
NOTES:
  • Achromatic lenses provide best image quality.
  • Fresnel lenses can be used to reduce the total length (2t1+t2)
  • Smaller total length should reduce edge effects and increase the range of angles.
  • For an easier, but less ideal, cloak, you can try the 3 lens cloak in the paper.
A patent has been filed for this cloaking device. Please contact UR Ventures for additional information.

Peeking Through Keyholes With Lasers... well, yes and no.

An imaging technique that measures the path of a laser to build up a three-dimensional picture could now let spies map an entire room through a tiny hole.

In 2012, researchers used a laser to see around corners. The system worked by firing short laser pulses at a nearby wall, bouncing light around a corner to a hidden object, which then bounces some of it back to a camera next to the laser...

Now Chenfei Jin of the Harbin Institute of Technology in China and colleagues have taken this a step further. They used a laser set-up to measure the 3D shape and position of three cardboard letters, spelling HIT, through a 2 centimetre hole in a nearby wall...

The letters were coated in highly reflective material while the rest of the room was covered in black light-absorbing cloth, so the technique might not work as well in a real-world setting...

Guy Satat of the Massachusetts Institute of Technology says he likes the work, but points out that if the hole were easily accessible, it would be easier for would-be spies to simply put a camera up against the wall and take a photo of the room.

Join Us for Our Next Exciting Adventure... Google Toggle... or, Pain in the Glass

Not a fan of Google Glass’s ability to turn ordinary humans into invisibly recording surveillance cyborgs? Now you can create your own “glasshole-free zone.”

Berlin artist Julian Oliver has written a simple program called Glasshole.sh that detects any Glass device attempting to connect to a Wi-Fi network based on a unique character string that he says he’s found in the MAC addresses of Google’s augmented reality headsets.


Install Oliver’s program on a Raspberry Pi or Beaglebone mini-computer and plug it into a USB network antenna, and the gadget becomes a Google Glass detector, sniffing the local network for signs of Glass users.  

When it detects Glass, it uses the program Aircrack-NG to impersonate the network and send a “deauthorization” command, cutting the headset’s Wi-Fi connection. It can also emit a beep to signal the Glass-wearer’s presence to anyone nearby. (more)

Graphene-Based, Ultra-Thin Light Detector - T-Ray Vision

A new prototype light detector uses graphene's light-absorbing properties to see in a broad band of light wavelengths that includes terahertz waves. These fall between the microwave and infrared bands, thereby making it possible to look just beneath the surface of opaque objects such as skin and plastic... 

So where might such a detector be used? In security scanners, for example, it could identify concealed weapons without invading bodily privacy. It could also make medical imaging safer and more effective.

Other applications include chemical sensing, remote bomb detection, night vision goggles/cameras, high-altitude telecommunications, manufacturing quality control (as terahertz waves penetrate cardboard and plastic), preventing premature car rusting, and even 3D printing.

A paper describing the research was published recently in the journal Nature. (more) (Get the T-shirt)

Green Group Suggested Video Cameras to Spy on Farmer

An environmental group that stands accused of overstepping its inspection authority and trespassing across a Virginia farm also tried to have video cameras installed to monitor the property. 

An officer of the Piedmont Environmental Council proposed that one of that group’s board members “runs a security company and could offer the use of security cameras to record visitors,” according to documents examined by The Daily Signal. 

Documents obtained by The Daily Signal show the environmental group sought not only to monitor Liberty Farm through increasingly invasive inspections but also to install the video cameras to monitor visitors.

However, the Virginia Outdoors Foundation, a quasi-state agency created by the state legislature to preserve open space, would not go along. (more)

FutureWatch: Eavesdropping on Potato Chip Bags... You may be next.

Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were able to recover intelligible speech from the vibrations of a potato-chip bag photographed from 15 feet away through soundproof glass.

In other experiments, they extracted useful audio signals from videos of aluminum foil, the surface of a glass of water, and even the leaves of a potted plant. The researchers will present their findings in a paper at this year’s Siggraph, the premier computer graphics conference.


 

“When sound hits an object, it causes the object to vibrate,” says Abe Davis, a graduate student in electrical engineering and computer science at MIT and first author on the new paper. “The motion of this vibration creates a very subtle visual signal that’s usually invisible to the naked eye. People didn’t realize that this information was there.” (more)

Spy Tradecraft FutureWatch - 3-D Room Scan Mapping

Despite the promise of Google's Movidius-equipped Project Tango, there are still no depth-sensing, SLR-stomping smartphones on the market. But Movidius thinks that could change soon, thanks to its brand new chip: the Myriad 2 vision processor unit (VPU). 

"The Myriad 2 is going to provide more than 20x the power efficiency of the Myriad 1, and enable camera features that were not possible before in mobile devices," CEO Remi El-Ouazzane tells me. If you'll recall, Tango's original tech brought faster focus, improved depth of field, near-optical zooming and higher light sensitivity to smartphone cameras (and now, tablets).



It also let researchers scan a room in 3D to provide interior navigation, among other cool tricks. (more)

From a Security Scrapbook Blue Blaze Irregular...
So, letting uncleared persons into secure facilities just became even more stupid. With new processing chips, surreptitious video recording becomes even more dangerous. Movidius makes the chips. And Matterport makes the 3D modelling software. This is very cool but at the same time very disturbing. How many tradecraft applications will this have? Security managers should see, at least, the Matterport video.

See around Corners. Turn Walls into Mirrors. Well, sort of...

The functional difference between a diffuse wall and a mirror is well understood: one scatters back into all directions, and the other one preserves the directionality of reflected light.
The temporal structure of the light, however, is left intact by both: assuming simple surface reflection, photons that arrive first are reflected first. In this paper, we exploit this insight to recover objects outside the line of sight from second-order diffuse reflections, effectively turning walls into mirrors. (more)

Proof the Surveillance Society is Making us Crazy - CV Dazzle

This is how bad things are getting...

"The NSA made me slather my face in make-up... I had slathered the paint on my face in order to hide from computers. The patterns in which I applied the paint were important: To the pixel-calculating machinations of facial recognition algorithms, they transformed my face into a mess of unremarkable pixels. In the computer’s vision, my face caused a momentary burst of confusion. That’s why the patterns are called computer vision dazzle (or CV dazzle). When it works, CV dazzle keeps facial-recognition algorithms from seeing a face...


...more unexpected was what CV dazzle taught me about the physical world. It reminded me of another tech experiment I’d undertaken

My phone’s Reminders app can tie a message to a specific place, it triggers an alert tone every time a user comes within 500 feet. I’d tried tying these reminders to a different kind of location—the 176 embassies and diplomatic missions in Washington, D.C. Whenever I got within a couple hundred feet of one, my phone sent me a little ping: “Iceland.” “Thailand.” “Equitorial New Guinea.”...

...here is the essence of CV dazzle’s strangeness: The very thing that makes you invisible to computers makes you glaringly obvious to other humans."  (more) (official site cvdazzle.com)

Israeli ‘Eavesdropper’ Hears You 1,000 Feet Away

A device developed by an Israeli scientist can pick up conversations from hundreds of feet away without a microphone. “Using a laser beam with a camera, we can detect the voice wave patterns of the sounds that a person makes when they are talking,” says Bar-Ilan University Professor Zev Zalevsky, who helped design the system. “We take these wave patterns and translate them back into voice, and thus can interpret what was said from even a long distance away.”

 The system is the latest use for a technology and device Zalevsky designed in 2011 together with Javier Garcia of the University of Valencia in Spain. Called the Opto-Phone, the device was designed to gather medical data about an individual, allowing doctors to read heartbeat, blood pressure or blood glucose levels from 100 meters away. With the latest tweaks to the Opto-Phone, Zalevsky told Channel 2 Tuesday night, the device can now detect voice wave patterns from up to 400 meters (about 1,200 feet) away. This makes it the perfect tool not only for “long-distance” medical diagnosis, but for long-distance eavesdropping, as well. 

Using a laser beam, an advanced camera and sensors, the Opto-Phone uses nano-photonics to detect movement on the surface of the body. This movement creates a “speckle pattern,” which can be read by the Opto-Phone. By analyzing this pattern, the system can “hear” the number of heartbeats in a person’s body, the rush of blood in the bloodstream and voice wave patterns as they bounce off two people engaged in a conversation. The technology is so precise, Zalevsky said, “we can differentiate between different people based on their position,” listening in on whatever they are involved in, Zalevsky told the Times of Israel.
