CSE tracks millions of downloads daily: Snowden documents

Canada’s electronic spy agency sifts through millions of videos and documents downloaded online every day by people around the world, as part of a sweeping bid to find extremist plots and suspects, CBC News has learned.

Details of the Communications Security Establishment project dubbed “Levitation” are revealed in a document obtained by U.S. whistleblower Edward Snowden and recently released to CBC News.

Under Levitation, analysts with the electronic eavesdropping service can access information on about 10 to 15 million uploads and downloads of files from free websites each day, the document says.

“Every single thing that you do — in this case uploading/downloading files to these sites — that act is being archived, collected and analyzed,” says Ron Deibert, director of the University of Toronto-based internet security think-tank Citizen Lab, who reviewed the document.
