A late study foundrecognizable images of human facesin eminent - res picture of optic , reminding us that surveillance technology improves more and more each 24-hour interval . But designers and technologist are operate on ways to keep our faces secret from nosiness cameras by combining the weakness of facial acknowledgement engineering with fashion .

How facial recognition works
Traditionally , when we talk about facial identification applied science , we are talking about a computer key a grimace in a picture or video , and identifying certain biometry of the face , such as the spacing between the eyes , the relative position of cheekbones , the shape of the jaw , and more . The human face has 80 client that can be used in facial realisation , but it only take between 14 and 22 nodes to identify a alone human face .
The magic , however , is getting a estimator to realize a face and these single node , and for that a program needs to be trained to discern a human face using a serial of training images . Once a program have sex what a face reckon like , it can create a mathematical representation of the face based on a series of standard faces , most notably the series of eigenvectors known as Eigenfaces . Below , you could see the OpenCV Face Recognition system in action as it analyzes the famous photograph of Lena Söderberg using an object detection framework develop by Paul Viola and Michael Jones :
This is a far from perfect system , however . As much as we hear story about eminent - end store using facial acknowledgement engineering science to pick out celebrity patron and Google banning facial realisation on Google Glass , there are plenty of weakness in this character of facial recognition technology . The engineering is fantabulous at recognizing faces dead - on and from certain angles , but it has a much hard prison term accurately identifying a aspect ’s biometric information when looking at a face in visibility or almost - visibility . In an interview with the BBClast year , Alex Kilpatrick , a facial recognition researcher at Texas - based Tactical Information Systems said that the simple way to thwart current facial recognition systems is to look at your feet ; it ’s subtle and prevents photographic camera climb on at eye - level or higher from bring forth a good look at your face . However , biometric researchers are constantly bet for way of life to improve upon these systems .
One system that may be on the horizon involves making a three - dimensional map of the human face — although if you ’re on the lam , these systems can patently be fool by change to the physical map of your peel , such as rhinoplasty . Another system currently being investigated imply using a cutis mark , recording and comparing unequalled pattern of a patch of skin — something that distinguishes even identical twins .
Can’t you just wear a pair of sunglasses?
If you want to fag a masquerade party that whole covers your case , you may surely ward off being recognized , but what if you opt for the much less flashy jazz group of a twain of sunglasses and a scarf joint wrapped around your mouth?A couplet of recent paper out of Institut Eurécomdiscussed betterment in facial recognitionin cases where the face is occluded by clothing or accessory . Object realization organisation can , in fact , agnise the presence of a duet of sunglasses or a scarf , then polish off the occluded portions of the face from the course of study ’s analysis of the face . For example , if you are wear out sunglasses , the system will discern the sunglasses and then ignore that part of your facial expression . The programme will then just analyze whatever is depart behind . Shengcai Liao , an adjunct professor at the Center for Biometrics and Security Research in Beijing , China , narrate the BBCthat it ’s potential to accredit faces with 30 % and in some cases 50 % occlusion . Increasingly , just covering your aspect is n’t enough .

So what can you wear so as to head off acknowledgement ?
Anti-Face War Paint
A few old age ago , a series of unusual hair and constitution aspect created by Adam Harveyswept across the Internetwith the promise that they would dish up as camouflage against facial recognition engineering science . So how does it work ? Harvey designed the looks base on OpenCV ’s system ( which is why he calls his projectCV Dazzle ) , and it is also think of to thwart the realisation systems eblearn and VeriLook . CV Dazzle is n’t just meant to hide your special biometric entropy ; it ’s mean to keep facial recognition system from detecting your brass at all .

One of the failing of the Eigenface system of rules that computer scientists mention again and again is that they are standard face : symmetrical with two eyes , a nose , and a mouth . The CV Dazzle reckon defy the expectations of a standard font by further asymmetry and obscure key features . Asymmetrical haircut can obnubilate one eye and radically modify the way your face is couch . Makeup that does n’t raise your feature film but instead places against the common tones and symmetry of your characteristic can make it hard for a facial identification organization to identify cheekbones or a os frontale . Facial recognition systems are expect for a face . CV Dazzle is meant to give you an “ anti - look . ”
Camera-Fighting LEDs
Last year , Isao Echizen , an associate prof at Tokyo ’s National Institute of Informatics , and Professor Seiichi Gohshi of Kogakuin University showed off their own anti - facial recognition accessory : a privacy vizor that uses close - infrared LEDsto hide the wearer ’s look from cameras . The mind is simple : the near - infrared light source is inconspicuous to the human eye , but seeable to camera , obscure the wearer ’s facial features by adding stochasticity to the camera ikon when the LEDs are unhorse without hide the wearer ’s visual sense . Although the prototype privacy visor is n’t exactly the most attractive solution , it does have the advantage of not occluding the wearer ’s face in face - to - face interactions . The privacy visor is for someone who want to look folks straight in both eyes but does n’t want their every movement tape on tv camera .

Fashion with Someone Else’s Face
In a rather cheeky attempt to screw with facial recognition technology — namely Facebook’s — designerSimone C. Niquillecame up with“REALFACE Glamoflage”t - shirt . These unearthly looking t - shirts have renowned mass ’s faces on them , so when FaceBook test to autotag your photographs , it appears that you ’re hang with a crowd of Britney Spearses or Barack Obamas . In an consultation with Wired , Niquille explained that the shirt were inspired by “ ugly shirt ” that cover the wearer ’s identity from William Gibson ’s refreshing Zero History . It could also serve as a way to reach privacy through omnipresence ; if you managed to get a ton of mass to wear Glamoflage shirts with your look on it , you would seem to be in a lot of places that you ’re not , at least when employing a facial recognition system like Facebook ’s .

Anti-Drone Fashion
Adam Harvey follow up his CV Dazzle project with a fashion argumentation aimed at concealing wearer from a different kind of facial recognition organisation , one based on thermal trope of the nerve . His Stealth Wear line uses lightweight metallic fabric to reflect the wearer ’s body heat , masking their thermal signature from drones . And unlike CV Dazzle , many of the part in Harvey ’s Stealth Wear assemblage look quite ordinary , much like meditative safety article of clothing .

Of of course , most of these seclusion fashions are gear toward specific types of facial recognition systems , and it ’s likely that we ’ll see designs change as facial credit systems change and improve . And some of these styles ( especially CV Dazzle ) are a bit visually extreme when liken to current mainstream fashion . It will be interesting to see if facial recognition technology reach out a pointedness where privacy from technology will genuinely help inform fashion .
