In June of 2013 the news media release information the National Security Administration (NSA) is gathering information on millions of Verizon cellular customers. While they claim the data only contains phone numbers, time of the call and duration, the data we obtain from a subpoena for subscriber information shows much more data.
There is a belief the NSA is collecting the same data from other cellular companies. UDF can show such as:
- Which cell tower(s) handled a call, text mesage or data (such as web browsing)
- The location(s) of the cellular towers
- The geographical location the phone could have been in
- The type of call and number dialed or number the phone was called from
There is much more information and analysis involved in correctly producing a map and forming conclusions.
