How to stop AI from recognizing your face in selfies


Fawkes has already been downloaded nearly half a million times from the project website. One user has also built an online version, making it even easier for people to use (though Wenger won’t vouch for third parties using the code, warning: “You don’t know what’s happening to your data while that person is processing it”). There’s not yet a phone app, but there’s nothing stopping somebody from making one, says Wenger.

Fawkes may keep a new facial recognition system from recognizing you—the next Clearview, say. But it won’t sabotage existing systems that have been trained on your unprotected images already. The tech is improving all the time, however. Wenger thinks that a tool developed by Valeriia Cherepanova and her colleagues at the University of Maryland, one of the teams at ICLR this week, might address this issue. 

Called LowKey, the tool expands on Fawkes by applying perturbations to images based on a stronger kind of adversarial attack, which also fools pretrained commercial models. Like Fawkes, LowKey is also available online.

Ma and his colleagues have added an even bigger twist. Their approach, which turns images into what they call unlearnable examples, effectively makes an AI ignore your selfies entirely. “I think it’s great,” says Wenger. “Fawkes trains a model to learn something wrong about you, and this tool trains a model to learn nothing about you.”

Unlike Fawkes and its followers, unlearnable examples are not based on adversarial attacks. Instead of introducing changes to an image that force an AI to make a mistake, Ma’s team adds tiny changes that trick an AI into ignoring it during training. When presented with the image later, its evaluation of what’s in it will be no better than a random guess.

Unlearnable examples may prove more effective than adversarial attacks, since they cannot be trained against. The more adversarial examples an AI sees, the better it gets at recognizing them. But because Ma and his colleagues stop an AI from training on images in the first place, they claim this won’t happen with unlearnable examples.

Wenger is resigned to an ongoing battle, however. Her team recently noticed that Microsoft Azure’s facial recognition service was no longer spoofed by some of their images. “It suddenly somehow became robust to cloaked images that we had generated,” she says. “We don’t know what happened.”

Microsoft may have changed its algorithm, or the AI may simply have seen so many images from people using Fawkes that it learned to recognize them. Either way, Wenger’s team released an update to their tool last week that works against Azure again. “This is another cat-and-mouse arms race,” she says.

For Wenger, this is the story of the internet. “Companies like Clearview are capitalizing on what they perceive to be freely available data and using it to do whatever they want,” she says.”

Regulation might help in the long run, but that won’t stop companies from exploiting loopholes. “There’s always going to be a disconnect between what is legally acceptable and what people actually want,” she says. “Tools like Fawkes fill that gap.”

“Let’s give people some power that they didn’t have before,” she says.

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

This startup’s AI is smart enough to drive different types of vehicles

The news: Wayve, a driverless-car startup based in London, has made a machine-learning model that can drive two different types of vehicle: a passenger car and a delivery van. It is the first time the same AI driver has learned to drive multiple vehicles.

Why it matters: While robotaxis have made it to a handful of streets in Phoenix and San Francisco, their success has been limited. Wayve is part of a new generation of startups ditching the traditional robotics mindset—where driverless cars rely on super-detailed 3D maps and modules for sensing and planning. Instead, these startups rely entirely on AI to drive the vehicles.

What’s next: The advance suggests that Wayve’s approach to autonomous vehicles, in which a deep-learning model is trained to drive from scratch, could help it scale up faster than its leading rivals. Read the full story.

Russia’s battle to convince people to join its war is being waged on Telegram

Putin’s propaganda: When Vladimir Putin declared the partial call-up of military reservists on September 21, in a desperate effort to try to turn his long and brutal war in Ukraine in Russia’s favor, he kicked off another, parallel battle: one to convince the Russian people of the merits and risks of conscription. And this one is being fought on the encrypted messaging service Telegram.

Opposing forces: Following the announcement, pro-Kremlin Telegram channels began to line up dutifully behind Putin’s plans, eager to promote the idea that the war he is waging is just and winnable.  But whether this vein of propaganda is working is far from certain. For all the work the government is doing to try to control the narrative, there’s a vibrant opposition on the same platform working to undermine it—and offering support for those seeking to dodge the draft.

NASA’s DART mission is on track to crash into an asteroid today

NASA’s Double Asteroid Redirection Test spacecraft, or DART, is on course to collide with the asteroid Dimorphos at 7.14pm ET today. Though Dimorphos is not about to collide with Earth, DART is intended to demonstrate the ability to deflect an asteroid like it that is headed our way, should one ever be discovered.

Read more about the DART mission, and how the crash is likely to play out.

The big story

The quest to learn if our brain’s mutations affect mental health

August 2021

Scientists have struggled in their search for specific genes behind most brain disorders, including autism and Alzheimer’s disease. Unlike problems with some other parts of our body, the vast majority of brain disorder presentations are not linked to an identifiable gene.

But a University of California, San Diego study published in 2001 suggested a different path. What if it wasn’t a single faulty gene—or even a series of genes—that always caused cognitive issues? What if it could be the genetic differences between cells? 

The explanation had seemed far-fetched, but more researchers have begun to take it seriously. Scientists already knew that the 85 billion to 100 billion neurons in your brain work to some extent in concert—but what they want to know is whether there is a risk when some of those cells might be singing a different genetic tune.

This startup’s AI is smart enough to drive different types of vehicles


Jay Gierak at Ghost, which is based in Mountain View, California, is impressed by Wayve’s demonstrations and agrees with the company’s overall viewpoint. “The robotics approach is not the right way to do this,” says Gierak.

But he’s not sold on Wayve’s total commitment to deep learning. Instead of a single large model, Ghost trains many hundreds of smaller models, each with a specialism. It then hand codes simple rules that tell the self-driving system which models to use in which situations. (Ghost’s approach is similar to that taken by another AV2.0 firm, Autobrains, based in Israel. But Autobrains uses yet another layer of neural networks to learn the rules.)

According to Volkmar Uhlig, Ghost’s co-founder and CTO, splitting the AI into many smaller pieces, each with specific functions, makes it easier to establish that an autonomous vehicle is safe. “At some point, something will happen,” he says. “And a judge will ask you to point to the code that says: ‘If there’s a person in front of you, you have to brake.’ That piece of code needs to exist.” The code can still be learned, but in a large model like Wayve’s it would be hard to find, says Uhlig.

Still, the two companies are chasing complementary goals: Ghost wants to make consumer vehicles that can drive themselves on freeways; Wayve wants to be the first company to put driverless cars in 100 cities. Wayve is now working with UK grocery giants Asda and Ocado, collecting data from their urban delivery vehicles.

Yet, by many measures, both firms are far behind the market leaders. Cruise and Waymo have racked up hundreds of hours of driving without a human in their cars and already offer robotaxi services to the public in a small number of locations.

“I don’t want to diminish the scale of the challenge ahead of us,” says Hawke. “The AV industry teaches you humility.”

Russia’s battle to convince people to join its war is being waged on Telegram


Just minutes after Putin announced conscription, the administrators of the anti-Kremlin Rospartizan group announced its own “mobilization,” gearing up its supporters to bomb military enlistment officers and the Ministry of Defense with Molotov cocktails. “Ordinary Russians are invited to die for nothing in a foreign land,” they wrote. “Agitate, incite, spread the truth, but do not be the ones who legitimize the Russian government.”

The Rospartizan Telegram group—which has more than 28,000 subscribers—has posted photos and videos purporting to show early action against the military mobilization, including burned-out offices and broken windows at local government buildings. 

Other Telegram channels are offering citizens opportunities for less direct, though far more self-interested, action—namely, how to flee the country even as the government has instituted a nationwide ban on selling plane tickets to men aged 18 to 65. Groups advising Russians on how to escape into neighboring countries sprung up almost as soon as Putin finished talking, and some groups already on the platform adjusted their message. 

One group, which offers advice and tips on how to cross from Russia to Georgia, is rapidly closing in on 100,000 members. The group dates back to at least November 2020, according to previously pinned messages; since then, it has offered information for potential travelers about how to book spots on minibuses crossing the border and how to travel with pets. 

After Putin’s declaration, the channel was co-opted by young men giving supposed firsthand accounts of crossing the border this week. Users are sharing their age, when and where they crossed the border, and what resistance they encountered from border guards, if any. 

For those who haven’t decided to escape Russia, there are still other messages about how to duck army call-ups. Another channel, set up shortly after Putin’s conscription drive, crowdsources information about where police and other authorities in Moscow are signing up men of military age. It gained 52,000 subscribers in just two days, and they are keeping track of photos, videos, and maps showing where people are being handed conscription orders. The group is one of many: another Moscow-based Telegram channel doing the same thing has more than 115,000 subscribers. Half that audience joined in 18 hours overnight on September 22. 

“You will not see many calls or advice on established media on how to avoid mobilization,” says Golovchenko. “You will see this on Telegram.”

The Kremlin is trying hard to gain supremacy on Telegram because of its current position as a rich seam of subterfuge for those opposed to Putin and his regime, Golovchenko adds. “What is at stake is the extent to which Telegram can amplify the idea that war is now part of Russia’s everyday life,” he says. “If Russians begin to realize their neighbors and friends and fathers are being killed en masse, that will be crucial.”
