Deepfake pics and videos set off Facebook’s fake news detector | Cyber Security

Facebook will begin officially checking videos and photos for authenticity as part of an expanding effort to stamp out , the company said last week.

Facebook has already responded to the fake news epidemic by checking articles that people post to its social media service for authenticity. To do this, it works with a range of third-party fact checking companies to review and rate content accuracy.

A picture’s worth a thousand words, though, and it was going to have to tackle fake news images eventually. In a post to its newsroom site on Thursday, it said:

To date, most of our fact-checking partners have focused on reviewing articles. However, we have also been actively working to build new technology and partnerships so that we can tackle other forms of misinformation. Today, we’re expanding fact-checking for photos and videos to all of our 27 partners in 17 countries around the world (and are regularly on-boarding new fact-checking partners). This will help us identify and take action against more types of misinformation, faster.

Facebook, which has been rolling out photo- and video-based fact checking since March, said that there are three main types of fake visual news. The first is fabrication, where someone forges an image with Photoshop or produces a video. One example is a photo from September 2017, which depicted a Seattle Seahawks player burning a US flag. The image, of a post-game celebration, had been doctored to insert the flag.

The next category is images that are taken out of context. For example, in 2013, a popular photograph on Facebook purportedly showed Raoni Metuktire, chief of the Brazilian Kayapó tribe, in tears after the government announced a license to build a hydroelectric dam. In fact, he was sobbing because he had been reunited with a family member.

The third category superimposes false text or audio claims over photographs. In Facebook’s example, a fake news outlet called ‘BBC News Hub’, superimposed unsubstantiated comments on a photo of Indian Prime Minister Narendra Modi, claiming that he has been lining his own pockets with public resources and is “The 7th Most Corrupted Prime Minister in the World 2018″(sic).
