UK unveils new technology to detect extremist videos online


The British government has unveiled a tool that it says can block extremist content on the Internet with reasonable accuracy.

According to the BBC, UK home secretary Amber Rudd said the government may end up legally forcing tech companies to use the tool.

ASI claims its proprietary software is able to detect the vast majority (94%) of Islamic State's activity online - with a reported accuracy score of 99.995%.

Anything the software identifies as potential IS material would be flagged up for a human decision to be taken.

"This government has been taking the lead worldwide in making sure that vile terrorist content is stamped out", said Rudd on a visit to Silicon Valley to meet with tech companies.

Mrs May has also frequently cajoled internet companies such as Facebook and Twitter to do more to prevent safe spaces online that allow extremism to proliferate.

The technology in question was created by the Home Office and ASI Data Science and uses machine learning artificial intelligence to analyse audio and video and determine whether it contains any extremist content.

It can be used by any platform and across a range of video-streaming and download sites in real time.

The system is to be made available to smaller companies, as the government says that these are increasingly being targeted by extremists to publish propaganda.

The news comes as Rudd is in the USA to meet with tech giants to discuss ways of working to collaboratively counteract the emergence of online extremist content.

The home secretary will also meet with the Global Internet Forum to Counter Terrorism, which was launched a year ago in the aftermath of the Westminster Bridge attack that left five dead.

The Home Office estimates that between July and the end of 2017, extremist material appeared in nearly 150 web services that had not been used for such propaganda before.

However, the bigger challenge is predicting which parts of the internet that jihadis will use next.
