April 4, 2001: Electronic Surveillance Techniques Reach New Heights

The BBC reports on advances in electronic surveillance. The US’s global surveillance program, Echelon, has become particularly effective in monitoring mobile phones, recording millions of calls simultaneously and checking them against a powerful search engine designed to pick out key words that might represent a security threat. Laser microphones can pick up conversations from up to a kilometer away by monitoring window vibrations. If a bug is attached to a computer keyboard, it is possible to monitor exactly what is being keyed in, because every key on a computer has a unique sound when depressed. [BBC, 4/4/2001] Furthermore, a BBC report on a European Union committee investigation into Echelon one month later notes that the surveillance network can sift through up to 90 percent of all Internet traffic, as well as monitor phone conversations, mobile phone calls, fax transmissions, net browsing history, satellite transmissions and so on. Even encryption may not help much. The BBC suggests that “it is likely that the intelligence agencies can crack open most commercially available encryption software.” [BBC, 5/29/2001]
