"A result of an activity called for in Presidential Policy Directive 28 (PPD-28), issued by President Obama in January 2014, to evaluate U.S. signals intelligence practices. The directive instructed the Office of the Director of National Intelligence (ODNI) to produce a report within one year 'assessing the feasibility of creating software that would allow the intelligence community more easily to conduct targeted information acquisition rather than bulk collection.' ODNI asked the National Research Council (NRC) - the operating arm of the National Academy of Sciences and National Academy of Engineering - to conduct a study, which began in June 2014, to assist in preparing a response to the President."--Publisher's description.
