Imagine this: You click on a news clip and see the President of the United States at a press conference with a foreign leader. The dialogue is real. The news conference is real. You share with a friend. They share with a friend. Soon, everyone has seen it. Only later you learn that the President’s head was superimposed on someone else’s body. None of it ever actually happened.
Sound farfetched? Not if you’ve seen this wild video from YouTube user Ctrl Shift Face:
In the clip, comedian Bill Hader shares a story about his encounters with Tom Cruise and Seth Rogen. As Hader, a sk**led impressionist, does his best Cruise and Rogen, those actors’ faces seamlessly, frighteningly melt into his own. The technology makes Hader's impressions that much more vivid, but it also illustrates how easy—and potentially dangerous—it is to manipulate video content.
What Is a Deepf**e?
The Hader video is an expertly crafted deepf**e, a technology invented in 2014 by Ian Goodfellow, a Ph.D. student who now works at Apple. Most deepf**e technology is based on generative adversarial networks (GANs).
GANs enable algorithms to move beyond classifying data into generating or creating images. This occurs when two GANs try to fool each other into thinking an image is “real.” Using as little as one image, a seasoned GAN can create a video clip of that person. Samsung’s AI Center recently released research sharing the science behind this approach.
“Crucially, the system is able to initialize the parameters of both the generator and the discriminator in a person-specific way, so that training can be based on just a few images and done quickly, despite the need to tune tens of millions of parameters,” said the researchers behind the paper. “We show that such an approach is able to learn highly realistic and personalized talking head models of new people and even portrait paintings.”

For now, this is only applied to talking head videos. But when 47 percent of Americans watch their news through online video content, what happens when GANs can make people dance, clap their hands, or otherwise be manipulated?
Why Are Deepf**es Dangerous?
If we forget the fact that there are over 30 nations actively engaged in cyberwar at any time, then the biggest concern with deepf**es might be things like the ill-conceived website Deepnudes, where celebrity faces and the faces of ordinary women could be superimposed on pornographic video content.
Deepnudes’ founder eventually canceled the site's launch, fearing “the probability that people will misuse it is too high.” Well, what else would people do with f**e pornography content?
“At the most basic level, deepf**es are lies disguised to look like t***h,” says Andrea Hickerson, Director of the School of Journalism and Mass Communications at the University of South Carolina. “If we take them as t***h or evidence, we can easily make false conclusions with potentially disastrous consequences.”
A lot of the fear about deepf**es rightfully concerns politics, Hickerson says. “What happens if a deepf**e video portrays a political leader inciting violence or panic? Might other countries be forced to act if the threat was immediate?”
With the 2020 e******ns approaching and the continued threat of cyberattacks and cyberwar, we have to seriously consider a few scary scenarios:
Weaponized deepf**es will be used in the 2020 e******n cycle to further ostracize, insulate, and divide the American e*****rate.
Weaponized deepf**es will be used to change and impact the v****g behavior, but also the consumer preferences of hundreds of millions of Americans.
Weaponized deepf**es will be used in spear phishing and other known cybersecurity attack strategies to more effectively target victims.
This means that deepf**es put companies, individuals, and the government at increased risk.
“The problem isn’t the GAN technology, necessarily,” says Ben Lamm, CEO of the AI company Hypergiant Industries. “The problem is that bad actors currently have an outsized advantage and there are not solutions in place to address the growing threat. However, there are a number of solutions and new ideas emerging in the AI community to combat this threat. Still, the solution must be humans first.”
What’s Being Done to Fight Deepf**es?
Last month, the U.S. House of Representatives’ Intelligence Committee sent a letter to Twitter, Facebook, and Google asking how the social media sites planned to combat deepf**es in the 2020 e******n. The inquiry came in large part after President Trump tweeted out a deepf**e video of House Speaker Nancy Pelosi:
