Listening In

Robert X. Cringely has an excellent in-depth writeup on the history of telephone taps:
Hitler on Line One
There's a Long History of Intercepting Foreign Communications,
and Some of It May Have Been Legal


Who is listening-in on your phone calls? Probably nobody. Right now, there is huge interest in phone tapping in the United States because the Bush Administration (through the National Security Agency) was caught listening in without appropriate court orders. What I have noticed is that, for all the talking and writing on this subject, there seems to be very little real information being presented. So this column is my attempt to share what I've learned about the topic. It might surprise you.

Intercepting communications for purposes of maintaining national security is nothing new. From before Pearl Harbor through 1945, EVERY trans-Atlantic phone call, cable and indeed letter was intercepted in Bermuda by the Coordinator of Information (COI) in the White House and later by the Office of Strategic Services (OSS). Sir William Stephenson revealed this in his autobiography, A Man Called Intrepid. They literally tapped the undersea cables and shipped all post to Europe through Bermuda, where every single call was monitored, every cable printed out, and every letter opened. FDR and Churchill needed intelligence and they took the steps they needed to get it.

The computer monitoring of cell phone conversations pales in both scale and significance. One fun fact from that monitoring: The CEO of International Telephone & Telegraph (ITT) reportedly spoke with Adolf Hitler on the phone from New York City every week of the war. According to the book The Sovereign State of ITT, the call was placed from New York to South America, and then used a cable from South America to Berlin. Key companies that maintained the German telephone network were ITT subsidiaries at that time, and communications were obviously of strategic importance for Germany; thus Hitler needed to speak with the CEO every week. ITT never stopped running the German phones during the war and were evidently allowed to continue doing so to gather just this sort of intelligence (that's me putting a positive spin on a disturbingly ambiguous relationship). So information technology's ability to eliminate borders in warfare is nothing new, even though it seemed to take the New York Times by surprise!
Robert then goes into how taps are done today (outsourced by the telcos) and the ramifications of the CALEA and FISA acts. Good stuff! Posted by DaveH at January 21, 2006 8:22 PM
