YouTube adds tool to help public figures report fake videos

YouTube is adding a detection tool for government officials, political candidates and journalists to catch and report videos that use artificial intelligence to display their likeness without permission.

The pilot programme, announced Tuesday, is arriving as social media companies and a patchwork of new laws start to address the problem of these so-called deepfakes, which are spreading as AI video technology rapidly improves. But the companies have largely relied on users to report fake material.
