Going to War Against Deepfakes

AS DAWN BROKE on Oct. 7, air raid sirens blasted out across Tel Aviv, sending Michael Matias and his girlfriend catapulting out of bed and down to the bomb shelter in their apartment building. Inside, the messages on their cell phones revealed the horror that had set off the alarm: Hamas gunmen were waging mass slaughter on Israelis and seizing hundreds of hostages, less than an hour's drive from where they huddled in safety.

In his stunned aftershock, Matias was struck by the implications for his tech startup. Late last year he had launched Clarity, an artificial intelligence company focused on detecting deepfakes in election campaigns; he believed such disinformation was an urgent threat to democracies. But with about 1,200 Israelis dead on Oct. 7 and the country at war, that mission would need to wait for now. He scrambled an emergency meeting that morning with Clarity's team, to trigger an action plan. "We said to each other, 'Our technology is going to be very meaningful here," says Matias, Clarity's CEO.

In the chaos following the massacres - the deadliest in the country's 75-year existence - Israel blocked Gaza's supplies of water, food, and electricity and dropped thousands of bombs on what it claimed were Hamas targets in the packed coastal enclave that's home to 2 million Palestinians. As the humanitarian crisis spiraled into a full-blown disaster, and more than 10,000 Palestinians killed, including civilians, in a month, macabre images flooded TV and phone screens, setting off spasms of rage and fraught protests worldwide. This was a war fought not only with munitions, but with information both real and fake. And along with the outrage on both warring sides, some people raised questions about whether the gruesome scenes were even real, or whether the images were so-called deepfakes that had been created with the help of artificial intelligence.
