Olaf Diegel, Professor of Additive Manufacturing at the University of Auckland, is known for his 3D printed guitars. However, he and his students carry out many more experiments and projects. Recently, he used a Mimaki 3DUJ-553 3D printer and 3D scan to make a copy of his face and see if he could fool face recognition. The $ 180,000 machine printed the face and two other models in acrylic in standard quality mode in 11 hours, including a 32-micron layer thickness.
Then Diegel and his team scraped off most of the soluble wax carrier by hand, placed it in the ultrasonic cleaning bath for about an hour, and then rinsed it off with cold water while brushing it with a stiff brush (all the last bits of the carrier material to remove) and finally wipe with isopropyl alcohol. Then I gave it about 3 or 4 coats of very matte clear coat (45% matte) and hand painted the eyes with a glossy clear coat to make them sparkle a bit. “
This seems like a pretty easily accessible task, and the resulting 3D printed face is remarkable. The investment for such a machine is just as foreseeable as the part costs. You can also order a face replica from a 3D printing service. This has some profound implications that we should address. People have been playing around in public for years trying to fool face recognition. Cybersecurity firm BKAV tricked the 2017 iPhone X FaceID with a 3D printed mask and later created a better mask while others fooled Android face scanning. Artist Sterling Crispin has created 3D printed data masks that protect your face from government surveillance and social media snappers.
Face recognition is a nascent field. We use it to unlock our phones and make purchases with the same device. Face recognition is also used for access control to buildings and sensitive facilities. Casinos and retail chains are taking security pictures of shoplifters and casino cheats and are constantly looking for crowds. The police can use facial recognition to quickly identify suspects or victims. Your photo will be compared to biometric data in your passport for access to countries. Facebook uses it to determine who is in your photos. In China, Ant Financial will spend over $ 400 million persuading people to use facial recognition for payments, and schools are using it to track attendance.
Apparently, “In China, toilet paper theft in public toilets is a big problem. Fortunately, facial recognition has come to the rescue. China has installed machines in public toilets that scan people’s faces before releasing toilet paper. It will stop giving paper to the same person until 9 minutes have passed. “
China is also a big user of facial recognition for security. Shanghai has 113 cameras per 1,000 people, and the country has facial recognition files for all of its citizens. The country has 200,000 million cameras. Megvii Technology, SenseTime, and YITU are facial recognition startups using AI that have received $ 1.4 billion, $ 2.6 billion and $ 400 million, respectively. Recognition of the face is key to China’s plans to maintain order in her country and beyond.
A journalist stated, “What the Communist Party is doing now with all this high-tech surveillance technology is trying to internalize control. Once you believe it’s true, you don’t even need the cops on the corner because you become your own cop. “
The utopian view would be that facial recognition is a ubiquitous technology that runs in the background of every social interaction and every moment of ours, promoting good behavior and safety. A more negative view would be that Orwell was indeed quite prescient. Another view of comedian Keith Lowell Jensen is, “What Orwell didn’t predict is that we would buy the cameras ourselves and that our greatest fear is that no one is watching.”
When we take these views and combine them, we find that Orwell’s surveillance state is likely much smarter and more efficient than the one Orwell came up with, while Aldous Huxley’s view that we would sink into a quagmire of self-absorption is, too right, only the drugs are many not one.
We are seeing a collision course that will affect our industry. Our cute little technology may just be one key to weaken a surveillance state, commit sophisticated crimes, fraud, terrorism, and regain freedoms in the future. 3D scanning and 3D printing are the easiest technologies for capturing and replicating 3D surfaces, such as: B. faces. Our technology could be used in the future to create veins and pores and other markers as well as corneas. We can thank Mimaki for creating millions of colors, and 3D printing can capture textures too. Our technology can evolve rapidly and like no other we can iterate and improve to meet new challenges. At the core of our technology is the ability to create new shapes quickly. And that is exactly what you would have to do in order to constantly outsmart a surveillance state for noble or criminal reasons.
We as an industry have to be prepared for this. Are we taking the pen argument? They can write beautiful poems and hate talking with a pen. It is not our job to regulate what our customers do with it. Unfortunately, in the past, legislators have quickly developed new laws specifically for 3D printing. Are we going to add a security feature that puts a tell-tale mark on every print, letting the scanners know that it’s an artificial copy? What would that mean for us? Are we taking sides? Do we as an industry undertake to suppress this? Or are we promoting free research into this technology, since, after all, any technology – even a fork – can be dangerous? This is something to think about because our technology is inventive and inevitably used for evil and good, to disrupt both bad and good.
