Given the rapidly increasing speed of facial recognition systems, the use of facial recognition technology in applications as disparate as mannequins in retail stores and border crossings around the world and drones and even televisions, this anti-facial recognition technology could be more needed now than ever.
Isao Echizen of NII along with Professor Seiichi Gohshi of Kogakuin University developed the technology – somewhat along the lines of the “drone-proof” clothing line – to protect individuals from having their privacy invaded by photographs taken by secret cameras or photographs taken unintentionally.
“Due of the popularization of portable terminals with built-in cameras and developments in SNS [Social Networking Services] and image search technologies, information such as when and where photographed subjects were is easily disclosed via photos taken and disclosed without their permission, which has resulted in a greater need to protect the privacy of these subjects,” states a press release from NII.
The technology developed by Echizen and Gohshi uses a near-infrared light source to disrupt the camera – and thus the photograph and facial recognition technology – without affecting the vision of the individual wearing the privacy visor.
An interesting application of this technology, which will likely become more important in the near future, is the ability to thwart augmented reality applications.
Augmented reality technology coupled with facial recognition is on the rise with companies like Viewdle, (recently acquired by Google according to WebProNews) funded by Blackberry, Qualcomm, Anthem Venture Partners, Western Technology Investment and Best Buy.
Viewdle enables people to “see the world through computer vision with face, object, and gesture recognition technology products that realize the full potential of the many advanced consumer devices that are now on the market—smartphones, tablets, and other camera-enabled devices.”
This type of technology is being deployed on a variety of platforms and thus this anti-facial recognition technology will only become more important as time goes on.
While previous proposals for protecting privacy include “physically shielding their faces or techniques for causing detection of people’s faces to fail by coloring their face or altering their hairstyle,” all of these require quite obvious alterations and in some cases can draw a great deal of attention.
Other methods of shielding one’s face, such as wearing masks, can even be prohibited in some places.
However this new system, which at this point is little more than clear safety goggles with LEDs attached which emit light visible only to cameras, would not be as easily outlawed.
The technology, though still in its infancy, is gaining a lot of attention in Japan, where it has already been featured on television.
According to Ryan Gallagher of Slate, Echizen said he has already received offers from companies seeking to work toward commercialized privacy visors in the future.
“We are developing an improved version of the privacy visor without power supply consisting of transparent materials that reflect or absorb specific wavelength,” Echizen said.
Most amazing of all is that Echizen predicts the final product will be incredibly cheap, costing “around $1 per unit.”
The goggles can essentially make the user invisible to facial recognition technologies and while they don’t quite look fashionable at this point, there is nothing stopping them from becoming increasingly sleek and less obvious.
Currently the required power supply is somewhat large so that would be another obstacle to be tackled in the near future.
Given the increasing concern with facial recognition technologies, I would be quite surprised if this type of technology and other anti-facial recognition systems did not catch on as facial recognition is deployed in even more everyday applications.
