Business Insider: A new algorithm could catch social-media trolls as they try to influence US elections. Researchers are offering it for free.. “The tool, described in a study published Wednesday in the journal Science Advances, works by learning to recognize known, common patterns associated with troll activity and disinformation campaigns. Russian troll accounts, for instance, have posted many links to far-right websites, but the content on those sites didn’t always match the posts’ accompanying text or images. Venezuelan trolls, meanwhile, have often posted fake websites.”

CNET: New tool debunks deepfakes of Trump and other world leaders

CNET: New tool debunks deepfakes of Trump and other world leaders. “Deepfakes of world leaders may be easier to debunk using a new detection method, according to an academic paper Wednesday. Researchers created profiles of the unique expressions and head movements made by powerful people — like Donald Trump, Hillary Clinton, Barack Obama and US presidential hopeful Elizabeth Warren — when they talk. That ‘soft biometric model’ helped detect a range of deepfakes, the kind of manipulated videos powered by artificial intelligence that have sprung up lately featuring Mark Zuckerberg and others.”

CNET: Adobe AI learns to spot the photo fakery Photoshop makes easy

CNET: Adobe AI learns to spot the photo fakery Photoshop makes easy. “Photoshop fakery is getting more and more sophisticated, but Adobe Systems is using AI to detect when it’s happened. Plenty of photo editing is no big deal, but in some situations — for example, photojournalism, viral photos of politicians or celebrities and forensic evidence used by law enforcement — you might want a better idea of what’s true or not.”
