Tech giants team up to curb online terror content

In a significant move, the world's leading tech companies have joined hands to prevent the spread of terrorist content on the internet amid pressure from world governments.
Facebook, Twitter, Microsoft and YouTube said they will set up a shared database to help them track and remove "violent terrorist imagery or terrorist recruitment videos."
The database will contain the digital "fingerprints" of the images and videos, allowing the tech firms to identify potential terrorist content more efficiently, the companies said in a statement yesterday, CNN reported.
The internet giants have been battling the spread across the internet of content linked to terrorist organisations.

Supporters of the militant group Islamic State (IS) have proved particularly adept at using social media for propaganda and recruitment.
Executives from top tech companies met with US government officials in January to talk about how terrorists are using social media to recruit attackers. In August, Twitter said it had suspended hundreds of thousands of accounts for promoting terrorism.

Such suspensions have drawn angry reactions from some users, including threats by IS supporters against the founders of Twitter and Facebook.
The Obama administration said in July that Twitter traffic for IS has declined significantly over the previous two years.
The tech firms have the challenge of balancing freedom of expression with preventing illegal activity and respecting users' privacy. They also face the potentially contentious task of determining what constitutes terrorist content.

The announcement from the four companies came hours after they were singled out by European officials for not removing hate speech from their platforms fast enough.
The European Commission found that only 40 per cent of hate speech published on the firms' platforms was reviewed within 24 hours.
The tech firms will start the terrorist content database with the digital fingerprints of "the most extreme and egregious terrorist images and videos we have removed from our services," they said.
Fingerprints for offending content found on one company's platform can be added so that the other participants can check if it's been posted on theirs as well.

More companies could become involved in the database in the future, the statement said.
