Malicious groups seeking to sow political discord in the U.S. and elsewhere have been embracing images and video to spread misinformation.
The company has been testing the image fact-checks since the spring, beginning with France and the news agency AFP. Now, it will send all of its 27 third-party fact-checkers disputed photos and videos to verify. Fact-checkers can also find them on their own.
Facebook will label images or video found to be untrue or misleading as such.
Facebook says the fact-checkers use visual verification techniques such as reverse image searching and analyzing image metadata to check the veracity of photos and videos.
