In April 2017, Facebook also used a photo matching system and introduced a mechanism in the US that prohibits uploading and sharing newly uploaded and shared pictures that were reported as revenge porn in the past. In addition, methods that combine image hashing and matching technology have been adopted by companies other than Facebook, and it is being used not only for revenge pornography but also for prevention of child abuse.
