“DeepFaceLab est un outil de création de deepfakes. Ses concepteurs, qui ont publié en libre accès leur code sur la plate-forme GitHub, estiment que la quasi-totalité des vidéos deepfakes créées le sont aujourd’hui avec ce logiciel. Sur leur page, on y trouve de nombreux exemples : le visage du milliardaire Elon Musk intégré au film Interstellar, l’acteur Arnold Schwarzenegger rajeuni, le chef de l’Etat nord-coréen Kim Jong-un en plein laïus sur la préservation de la démocratie… Mais aussi, plus bas, un lien vers MrDeepFakes, un site pornographique.”

“At first glance, Ramsey’s profile looks like many others on LinkedIn: the bland headshot with a slightly stiff smile; a boilerplate description of RingCentral, the software company where she says she works; and a brief job history. She claims to have an undergraduate business degree from New York University and gives a generic list of interests: CNN, Unilever, Amazon, philanthropist Melinda French Gates. But there were oddities in the photo: the single earring and strange hair, the placement of her eyes, the blurry background. Alone, any of these clues might be explained away, but together, they aroused DiResta’s suspicions […].
That chance message launched DiResta and her colleague Josh Goldstein at the Stanford Internet Observatory on an investigation that uncovered more than 1,000 LinkedIn profiles using what appear to be faces created by artificial intelligence.”

“Deepfakes have become more believable in recent years. In some cases, humans can no longer easily tell some of them apart from genuine images. Although detecting deepfakes remains a compelling challenge, their increasing sophistication opens up more potential lines of inquiry, such as: What happens when deepfakes are produced not just for amusement and awe, but for malicious intent on a grand scale? Today, we — in partnership with Michigan State University (MSU) — are presenting a research method of detecting and attributing deepfakes that relies on reverse engineering from a single AI-generated image to the generative model used to produce it. Our method will facilitate deepfake detection and tracing in real-world settings, where the deepfake image itself is often the only information detectors have to work with.”

“Lyu says a skilled forger could get around his eye-blinking tool simply by collecting images that show a person blinking. But he adds that his team has developed an even more effective technique, but says he’s keeping it secret for the moment. “I’d rather hold off at least for a little bit,” Lyu says. “We have a little advantage over the forgers right now, and we want to keep that advantage.””
