coondoggie writes "Better algorithms to spot patterns and trends within the mass of information the Department of Homeland Security sees everyday are key to national security. That was but one of the talking points DHS chief Janet Napolitano focused on in a lecture on the role of science and technology at the Massachusetts Institute of Technology today. 'DHS is part of the nation's Intelligence Community, which receives more terabytes of data each day than the entire text holdings of the Library of Congress. The National Counterterrorism Center's 24-hour Operations Center receives 8,000 to 10,000 pieces of counterterrorist information every day. We receive data about all of this, and it is clearly too much to suggest that the simplistic "connect the dots" analogy accurately represents what an analyst must do. Very quickly, you can see that "Big Data" – more so than the lack of data – becomes the most pressing problem. At the same time, the threats implicated by the data are not static.'"
