Deepfakes of Vice President Kamala Harris are proliferating on X.Photo illustration; Rafael Henrique/ZUMA For the second time in less than two weeks, a doctored video of Vice President Kamala Harris has spread widely on Elon Musk's social media platform X. A video known as a "deepfake" that was posted on X on Saturday appears to show Harris repeating herself over and over again, using a crude audio rendering made to seem like Harris is struggling to finish a complete sentence. The altered video uses footage from an appearance by Harris and President Joe Biden following Friday's historic prisoner swap that freed Wall Street Journal reporter Evan Gershkovich and others. The video is obviously manipulated and easily debunked by viewing the unaltered footage (you can watch that here at about the 1:30 mark), which shows Harris speaking smoothly, without repeating the same words and phrases as portrayed in the doctored video. The video, whose origin is unclear, was posted by Trump himself on Truth Social on Saturday, accompanied by a rant in which he calls Harris "DUMB!" and "extremely Low IQ."

Facebook and Twitter earlier this week took down social media accounts associated with the Internet Research Agency, the Russian troll farm that interfered in the U.S. presidential election four years ago, that had been spreading misinformation to up to 126 million Facebook users. Today, Facebook rolled out measures aimed at curbing disinformation ahead of Election Day in November. Deepfakes can make epic memes or put Nicholas Cage in every movie, but they can also undermine elections. As threats of election interference mount, two teams of AI researchers have recently introduced novel approaches to identifying deepfakes by watching for evidence of heartbeats. Existing deepfake detection models focus on traditional media forensics methods, like tracking unnatural eyelid movements or distortions at the edge of the face.

While it looks like another tale of internet magic, it points to something darker stirring in the internet's depths. This story was originally published August 19, 2019. The video exists thanks to deepfake technology and while its realism is still in its infancy, it's fast becoming one of the most terrifying developments in technology. To better understand how it works and what it means the future, we peeked under the covers. A update to Virginia, U.S.A.'s law against revenge porn banning the distribution of videos and images that have been deepfaked - modified using machine learning algorithms to picture someone else - or otherwise created with the intent to "coerce, harass, or intimidate" a victim went into effect on Tuesday, per CNET.

When Stephen Hawking warned of the dangers of Artificial Intelligence in 2015, his concerns were about the Superhuman AI that would pose an existential risk to humanity. But in recent years, much more imminent danger of AI has emerged that even a genius like Hawking could not have predicted. Deepfakes depict people in videos they never appeared in, saying things they never said and doing things they never really did. Some of the harmless ones have the actor Nicolas Cage's face superimposed on his Hollywood's peers while the more serious and dangerous ones target politicians like the US House Speaker Nancy Pelosi. Deeptrace, a cybersecurity startup based in Amsterdam found 14,698 deepfakes in June and July, an 84% increase since December of 2018 when the number of AI-manipulated videos was 7,964.

But, says Kambhampati, the rapid improvements in deepfake technology means that we will soon have to rely on AI techniques to detect what the human eye cannot. "There is not a 100% foolproof way of identifying deepfakes, not even for AI researchers," Thomas says. "Detection is always going to be an arms race. As people develop more accurate detection algorithms, fakers will develop even more sophisticated frauds." There are non-technical ways to sniff out a deepfake, just like other forms of disinformation. Ask yourself: Who is the person publishing this information?

Facebook says it is banning "deepfake" videos, the false but realistic clips created with artificial intelligence and sophisticated tools, as it steps up efforts to fight online manipulation. But the policy leaves plenty of loopholes. The social network said late Monday that it's beefing up its policies for removing videos edited or synthesized in ways that aren't apparent to the average person, and which could dupe someone into thinking the video's subject said something he or she didn't actually say. Created by artificial intelligence or machine learning, deepfakes combine or replace content to create images that can be almost impossible to tell are not authentic. "While these videos are still rare on the internet, they present a significant challenge for our industry and society as their use increases," Facebook's vice president of global policy management, Monika Bickert, said in a blog post.

Deepfake videos could be commonplace and found across the media and online platforms within six months, according to a leading expert. The idea of the videos is to look completely real and show people doing things they never did. These are created by complex computing and artificial intelligence and have caused outrage recently. Moving images can be created from just a single image of a person and US politician Nancy Pelosi, Facebook founder Mark Zuckerberg and even the Mona Lisa have been used in the convincing clips already. The video that kicked off the concern last month was a doctored video of Nancy Pelosi (pictured), the speaker of the US House of Representatives.

False news has consistently been growing around us, primarily as clickbait, and often tends to go viral. These are articles and stories created solely to mislead and misinform people into believing narratives that otherwise hold no merit. According to research published in Science magazine, the propagation of such media could be attributed to the fact that humans are more likely to spread lies faster than the truth. The primary sources of information used to be journalists and authentic media outlets that had to verify their sources and the information they received; sadly, this isn't always the case anymore. With advancements made in technology, the rumor and propaganda mills have been handed over to advanced AI algorithms that are designed to create believable content--which usually isn't true.

Deepfakes are created using artificial intelligence and facial mapping technology to yield false, but realistic clips. Celebrities and public figures, such as Facebook CEO Mark Zuckerberg, have been "featured" in deepfake videos.
