How to Hide from Face Detection Technology (Assuming You Need To Do So)

As a society, we do not appear to have much of a problem with our loss of privacy.

Convenience is evidently a fair trade for what privacy we have left and the consequences be damned.

Well, maybe not totally damned. Reports suggest there may be some growing squeamishness about facial recognition. TMI (too much information)? Too personal? The data are not clear, yet, on why the sudden loss of confidence in this latest aspect of the bare-all internet world in which we post pictures, histories and financial data for all and sundry to paw over. But, we suppose, the face is reported to be the mirror of the soul, and perhaps we are not quite ready to sell all of it on eBay. JL

John Sutter reports in CNN:
If you take Adam Harvey's advice, here's what you might wanna wear to a party this weekend: A funny hat, asymmetrical glasses, a tuft of hair that dangles off your nose bridge and, most likely, a black-and-white triangle taped to your cheekbone. Optional: Cubic makeup patterns all around your eyes.

All of these other worldly fashion accessories – which could leave a person looking kind of like an opulent villain from "The Hunger Games" - have a singular goal: to stop your face from being detected by cameras and computers.
Called CV Dazzle (short for "computer vision dazzle;" more on the name later), Harvey's project is a provocative and largely theoretical response to the rise of surveillance cameras on street corners and face-detecting technology that's been incorporated into social networking sites like Facebook and Flickr.

If you employ these techniques, Harvey, 30, hopes computers won't even know you have a face:

I don’t want to be unrealistic about it. It’s a pretty conceptual project but it seems to touch on a subject that people are still trying to figure out, which is how to adapt to living in surveillance societies, where not only are you being watched by government surveillance but by citizen surveillance and social-media-type surveillance.

The face appendages aim to trick face detection software by obscuring computer-readable parts of your face. According to Harvey, the key part of the face that computers can read is the "nose bridge," or the area between the eyes. If you can obscure that, you have a good chance of tricking computers into thinking you don't have a face, he said. Another technique is to create an "anit-face," which is less terrifying than it sounds since it just means inverting your face's color scheme. So the black-and-white triangles on the cheeks aim to achieve this effect.

Or, you could just sport a popped collar or a hoodie. More from Harvey:

One idea I’m working on is a double flip-up collar. It’s not much different from a hoodie except that you can fold it down and it’s a new style. The hoodie works great, but of course it’s kind of suspicious.

Asymmetry also fools computers, he said, since software first looks for symmetry in a face.

Harvey developed this concept as a grad-student project at New York University starting in 2010. He hopes to soon put out a fashion guide to avoiding face detection and wants to work with fashion designers to create accessories that trick peeping cameras. He's also working on a computer program that would allow people to draw their own anti-detection fashion, then test it virtually to see if it actually works before they go wandering out of the house with bangs hanging over their noses.

Oh, and the name: "Dazzle" refers to a particular type of camouflage that was used by ships in World War I. The cubist-style pattern on the boats wasn't meant to blend into the surroundings, exactly, but it did have a confusing effect, he said. "Zebras use dazzle camouflage," he said. "If they're all running around it’s increasingly difficult to se how many there are. That’s the advantage to them."

Harvey said he's not completely against face detection in all cases, but he thinks the technology "oscillates between cool and freaky." The public thinking on privacy, has "really turned upside down," he said. "Anything you do in favor of privacy can raise a lot of suspicion now."

He doesn't take things so seriously that he actually wears this stuff to parties, however. He's actually never tried that himself, he said, but is trying to come up with a hat that will look cool and still could conceal his identity - at least from the computers.
