NSA Snooping on Cell Phone Calls
A recent article in the London Review of Books revealed that a number of private companies now sell off-the-shelf data-mining solutions to government spies interested in analyzing mobile-phone calling records and real-time location information. These companies include ThorpeGlen, VASTech, Kommlabs, and Aqsacom—all of which sell “passive probing” data-mining services to governments around the world.
ThorpeGlen, a U.K.-based firm, offers intelligence analysts a graphical interface to the company’s mobile-phone location and call-record data-mining software. Want to determine a suspect’s “community of interest“? Easy. Want to learn if a single person is swapping SIM cards or throwing away phones (yet still hanging out in the same physical location)? No problem.
In a Web demo (PDF) (mirrored here) to potential customers back in May, ThorpeGlen’s vice president of global sales showed off the company’s tools by mining a dataset of a single week’s worth of call data from 50 million users in Indonesia, which it has crunched in order to try and discover small anti-social groups that only call each other.
