Several Web Firms Secretly Deploying Tech To Tackle Online Radicalisation
Such a system would catch attempts to repost content already identified as unacceptable, but would not automatically block videos that have not been seen before.
The companies would not confirm that they are using the method or talk about how it might be employed, but numerous people familiar with the technology said posted videos could be checked against a database of banned content to identify new postings of, say, a beheading or a lecture inciting violence.
The two sources would not discuss how much human work goes into reviewing videos identified as matches or near-matches by the technology . They also would not say how videos in the databases were initially identified as extremist.
Use of the technology is likely to be refined over time as internet companies continue to discuss the issue internally and with competitors and other interested parties.In late April, amid pressure from US President Barack Obama and European leaders concerned about online radicalisation, internet companies including Alphabet Inc’s YouTube, Twitter Inc, Facebook Inc and CloudFlare held a call to discuss options, including a content-blocking system put forward by the private Counter Extremism Project, according to one person on the call and three who were briefed on what was discussed. The discussions un derscored the central but difficult role some of the world’s most influential companies now play in addressing issues such as terrorism, free speech and the lines between government and corporate authority .
The firms now using automation are not publicly discussing it, two sources said, in part out of concern that terrorists might learn how to manipulate it or that repressive regimes might insist the technology be used to censor opponents.
