The Times profiled an 18-year-old Ukrainian lady named “Luba Dovzhenko” in March for example life below siege. She, the article claimed, studied journalism, spoke “dangerous English,” and started carrying a weapon after the Russian invasion.
The difficulty, nevertheless, was that Dovhenko doesn’t exist in actual life, and the story was taken down shortly after it was printed,
Luba Dovhenko was a pretend on-line persona engineered to capitalize on the rising curiosity in Ukraine-Russia conflict tales on Twitter and achieve a big following. The account not solely by no means tweeted earlier than March, nevertheless it additionally had a special username, and the updates it had been tweeting, which is what presumably drew The Occasions’ consideration, had been ripped off from different real profiles. Essentially the most damning proof of her fraud, nevertheless, was proper there in her face.
In Dovhenko’s profile image, a few of her hair strands had been indifferent from the remainder of her head, a couple of eyelashes had been lacking, and most significantly, her eyes had been strikingly centered. They had been all telltale indicators of a man-made face coughed up by an AI algorithm.

Dovhenko’s face was fabricated by the tech behind deepfakes, an more and more mainstream approach that permits anybody to superimpose a face over one other particular person’s in a video and is employed for all the things from revenge porn to manipulating world leaders’ speeches. And by feeding such algorithms thousands and thousands of images of actual individuals, they are often repurposed to create lifelike faces like Dovhenko’s out of skinny air. It’s a rising downside that’s making the battle towards misinformation much more tough.
A military of AI-generated pretend faces
Over the previous few years, as social networks crack down on faceless, nameless trolls, AI has armed malicious actors and bots with a useful weapon: the power to look alarmingly genuine. In contrast to earlier than, when trolls merely ripped actual faces off the web and anybody may unmask them by reverse-imaging their profile image, it’s virtually unattainable for somebody to do the identical for AI-generated pictures as a result of they’re contemporary and distinctive. And even upon nearer inspection, most individuals can’t inform the distinction.
Dr. Sophie Nightingale, a psychology professor on the U.Okay.’s Lancaster College, discovered that folks have only a 50% probability of recognizing an AI-synthesized face, and lots of even thought of them extra reliable than actual ones. The means for anybody to entry “artificial content material with out specialised information of Photoshop or CGI,” she instructed DailyTech, “creates a considerably bigger risk for nefarious makes use of than earlier applied sciences.”
What makes these faces so elusive and extremely practical, says Yassine Mekdad, a cybersecurity researcher on the College of Florida, whose mannequin to identify AI-generated photos has a 95.2% accuracy, is that their programming (often called a Generative Adversarial Community) makes use of two opposing neural networks that work towards one another in an effort to enhance a picture. One (G, generator) is tasked with producing the pretend photos and deceptive the opposite, whereas the second (D, discriminator) learns to inform aside the primary’s outcomes from actual faces. This “zero-sum sport” between the 2 permits the generator to provide “indistinguishable photos.”
And AI-generated faces have certainly taken over the web at a breakneck tempo. Aside from accounts like Dovhenko’s that use synthesized personas to rack up a following, this know-how has recently powered rather more alarming campaigns.
When Google fired an AI ethics researcher, Timnit Gebru, in 2020 for publishing a paper that highlighted bias within the firm’s algorithms, a network of bots with AI-generated faces, who claimed they used to work in Google’s AI analysis division, cropped up throughout social networks and ambushed anybody who spoke in Gebru’s favor. Comparable actions by nations like China have been detected selling authorities narratives.
On a cursory Twitter assessment, it didn’t take me lengthy to search out a number of anti-vaxxers, pro-Russians, and extra — all hiding behind a computer-generated face to push their agendas and assault anybody standing of their manner. Although Twitter and Fb repeatedly take down such botnets, they don’t have a framework to sort out particular person trolls with an artificial face although the previous’s deceptive and misleading identities coverage “prohibits impersonation of people, teams, or organizations to mislead, confuse, or deceive others, nor use a pretend id in a way that disrupts the expertise of others.” That is why after I reported the profiles I encountered, I used to be knowledgeable they didn’t violate any insurance policies.
Sensity, an AI-based fraud options firm, estimates that about 0.2% to 0.7% of individuals on common social networks use computer-generated pictures. That doesn’t seem to be a lot by itself, however for Fb (2.9 billion customers), Instagram (1.4 billion customers,) and Twitter (300 million customers), it means thousands and thousands of bots and actors that doubtlessly could possibly be a part of disinformation campaigns.
The match proportion of an AI-generated face detector Chrome extension by V7 Labs corroborated Sensity’s figures. Its CEO, Alberto Rizzoli, claims that on common, 1% of the pictures individuals add are flagged as pretend.
The pretend face market
Part of why AI-generated photos have proliferated so rapidly is how easy it is to get them. On platforms like Generated Photos, anyone can acquire hundreds of thousands of high-res fake faces for a couple of bucks, and for people who need a few for one-off purposes like personal smear campaigns, they can download them from websites such as thispersondoesnotexist.com, which auto-generates a new synthetic face every time you reload it.
These websites have made life especially challenging for people like Benjamin Strick, the investigations director at the U.K.’s Centre for Information Resilience, whose team spends hours every day tracking and analyzing online deceptive content.
“If you roll [auto-generative technologies] into a package of fake-faced profiles, working in a fake startup (through thisstartupdoesnotexist.com),” Strick told DailyTech, “there’s a recipe for social engineering and a base for very deceptive practices which can be setup within a matter of minutes.”
Ivan Braun, the founder of Generated Photos, argues that it’s not all bad, though. He contends that GAN photos have plenty of positive use cases — like anonymizing faces in Google Maps’ street view and simulating virtual worlds in gaming — and that’s what the platform promotes. If someone is in the business of misleading people, Braun says he hopes his platform’s antifraud defenses will be able to detect the harmful activities, and that eventually social networks will be able to filter out generated photos from authentic ones.
But regulating AI-based generative tech is tricky, too, since it also powers countless valuable services, including that latest filter on Snapchat and Zoom’s smart lighting features. Sensity CEO Giorgio Patrini agrees that banning services like Generated Photos is impractical to stem the rise of AI-generated faces. Instead, there’s an urgent need for more proactive approaches from platforms.
Until that happens, the adoption of synthetic media will continue to erode trust in public institutions like governments and journalism, says Tyler Williams, the director of investigations at Graphika, a social network analysis firm that has uncovered some of the most extensive campaigns involving fake personas. And a crucial element in fighting against the misuse of such technologies, Williams adds, is “a media literacy curriculum starting from a young age and source verification training.”
How to spot an AI-generated face?
Lucky for you, there are a few surefire ways to tell if a face is artificially created. The thing to remember here is that these faces are conjured up simply by blending tons of photos. So though the actual face will look real, you’ll find plenty of clues on the edges: The ear shapes or the earrings might not match, hair strands might be flying all over the places, and the eyeglass trim may be odd — the list goes on. The most common giveaway is that when you cycle through a few fake faces, all of their eyes will be in the exact same position: in the center of the screen. And you can test with the “folded train ticket” hack, as demonstrated right here by Strick.
Nightingale believes essentially the most important risk AI-generated pictures pose is fueling the “liar’s dividend” — the mere existence of them permits any media to be dismissed as a pretend. “If we can not purpose about primary information of the world round us,” she argues, “then this locations our societies and democracies at substantial threat.”
