 Project Information

2015_PPDBulk Collection of Signals Intelligence: Technical Options assesses the feasibility of creating software that would allow the U.S. intelligence community more easily to conduct targeted information acquisition rather than bulk collection of signals intelligence. It concludes that although there is no software technique that can fully substitute for bulk collection, software can be developed to more effectively target collection and to control the use of collected data.
