The Guardian newspaper in the U.K. published a Top Secret U.S. court that requires Verizon to hand over all call metadata on its networks on a daily basis to the National Security Agency (NSA).
The order reportedly covers all calls, both domestic and international inbound or outbound calls in the United States handled by Verizon.
Telephony metadata, as defined in the order, includes comprehensive communications routing information, session identifying information (e.g., originating and terminating telephone number, International Mobile Subscriber Identity (IMSI) number, International Mobile station Equipment Identity (IMEI) number, etc.), trunk identifier, telephone calling card numbers, and time and duration of call.
