UC Berkeley's Farid cautioned that it's not just the content that poses risks, but the ease of how quickly misinformation can travel online through social media. A 2019 report from Sensity, a company that tracks visual threats, found that nonconsensual deepfake pornography accounted more than 90% of all deepfake material online. While Ume's videos have been made with tongue very much in cheek, there are more nefarious cases in which deepfakes have been used, including nonconsensual deepfake pornography. Investigations Where Are The Deepfakes In This Presidential Election? The artist, who told CNET that his videos are strictly a creative pursuit, also wanted to bring awareness to the advancement of deepfakes. "He's a really talented actor," Ume told The Verge. Ume credits Fisher for nailing Cruise's likeness, from the intense eye contact to his signature laugh. Still, he told the website, it took a couple of months to train a machine learning algorithm by feeding a trove of Hollywood footage of Cruise through high-end graphics processors. Using open-source deepfake software, existing editing tools and his own visual effects expertise, Ume said, "I make sure you don't see any of the glitches." He also relied on the talents of actor Miles Fisher, a Cruise lookalike, to impersonate the movie star before giving Fisher a digital face transplant. To the trained eye, Farid says a distortion of Cruise's pupils in the videos was a red flag for spotting the fakery.Ģ020 Election: Secure Your Vote Why Fake Video, Audio May Not Be As Powerful In Spreading Disinformation As FearedĬhris Ume, a visual effects artist who created the Cruise deepfakes, told The Verge that each video clip was the product of weeks of work. "Every three to four months a video hits Tik Tok, YouTube, whatever, and it's just - wow, this is much, much better than before," he said. "This is clearly a new category of deepfake that we have not seen before," said Farid, who researches digital forensics and misinformation.ĭeepfakes have been around for years, but, Farid says, the technology has been steadily advancing. Hany Farid, a professor at the University of California, Berkeley, told NPR's All Things Considered that the Cruise videos demonstrate a step up in the technology's evolving sophistication. The videos, uploaded to TikTok in recent weeks by the account have raised new fears over the proliferation of believable deepfakes - the nickname for media generated by artificial intelligence technology showing phony events that often seem realistic enough to dupe an audience. In a crop of viral videos featuring Tom Cruise, it's not the actor's magic trick nor his joke-telling that's deceptive - but the fact that it's not actually Tom Cruise at all.
