Sentinel
Sentinel works with government and media defense agencies around the world in an effort to create a so-called “trust layer for the internet.” The company reportedly relies on four different, separate layers of deepfake defense. On the most basic layer, Sentinel scans documents for evidence of hashes (basically digital breadcrumbs) associated with known deepfaked materials. Other deeper layers of defense use AI to analyze faces for signs of visual manipulation and another that looks for changes in audio.
“My family used to live under the world’s biggest disinformation apparatus—the Soviet Union,” Sentinel CEO Johannes Tammekänd said. “That’s why we know firsthand the consequences of information warfare and why it is one of the biggest threats to democracies.
