UK govt unveils multi-platform system to detect terrorist content online

Wednesday 14 February 2018 | 09:39 CET | News

The UK’s Home Office said it has found a way to automatically detect terrorist content on any online platform. Developed by the Home Office and ASI Data Science, the system uses advanced machine learning to analyse the audio and visuals of a video to determine whether it could be Daesh propaganda. 

The Home Office said the tool has an extremely high degree of accuracy. For example, if it analyses 1 million randomly selected videos, only 50 would require additional human review. It can also be used by any platform, and integrated into the upload process, so that the majority of video propaganda is stopped before it ever reaches the internet. 

The Home Office and ASI will be sharing the methodology behind the new model with smaller companies, in order to help combat the abuse of their platforms by terrorists and their supporters. 

A Home Office study showed that Daesh supporters used more than 400 unique online platforms to push out their material in 2017, highlighting the importance of technology that can be applied across different platforms. Previous research found that most links to Daesh propaganda are disseminated within 2 hours of release, while a third of all links are disseminated within the first hour.
