"Starting today, we commit to the creation of a shared industry database of 'hashes' — unique digital 'fingerprints' — for violent terrorist imagery or terrorist recruitment videos or images that we have removed from our services. By sharing this information with each other, we may use the shared hashes to help identify potential terrorist content on our respective hosted consumer platforms," the statement issued on Monday said.
Daesh has been actively using social media to promote its values globally, thus, attracting new recruits. The terrorists reportedly used Twitter and Telegram, in particular, for communication before Paris attacks in November 2015. Telegram channels have also served as a propaganda platform for terrorists.
There have been different approaches to countering the Islamic State on Internet, including massive state surveillance and raids of social media against terrorist accounts. Since mid-2015 through August 2016 Twitter has suspended 235,000 accounts for violation of its policies regarding the promotion of terrorism and violent threat.
