An NSA Riddle.
At 11:18 pm, March 12, 2006, a person dialing from (202) 224-4521 reached the following number: (760) 471-8418.
We have not recorded the content of that call. We don’t know who made the call, or who was called. We only know the number from which the call originated, and the number reached. And the fact that the conversation lasted six minutes and ten seconds.
Data is ever discoverable, as we’ve seen time and time again when credit card numbers have been stolen by the million. But this data, since it consists solely of telephone numbers, is entirely safe. It can tell us nothing damaging.
It’s a riddle, kids, can you tell me who called who?
