NSA claims know-how to ensure no illegal spying
Monday, June 10, 2013
WASHINGTON (AP) — The supersecret agency with the power and legal authority to gather electronic communications worldwide to hunt U.S. adversaries says it has the technical know-how to ensure it’s not illegally spying on Americans.
But mistakes do happen in data-sifting conducted mostly by machines, not humans. Sometimes, former intelligence officials say, that means intelligence agencies destroy material they should not have seen, passed to them by the Fort Meade, Md.-based National Security Agency.
The eavesdropping, code-breaking agency is fighting back after last week’s revelations of two surveillance programs that have raised privacy concerns.
One program collects hundreds of millions of U.S. phone records. The second gathers audio, video, email, photographic and Internet search usage of foreign nationals overseas, and probably some Americans in the process, who use major providers such as Microsoft, Google, Apple, and Yahoo.
The director of national intelligence, James Clapper, said the NSA’s programs do not target U.S. citizens and that the agency uses a process known as “minimization” to sift out data from “any U.S. persons whose communications might be incidentally intercepted.”
His statement Saturday said that “the dissemination of information about U.S. persons is expressly prohibited unless it is necessary to understand foreign intelligence ... is evidence of a crime or indicates a threat of death or serious bodily harm.”
While the NSA has deferred any public comment to Clapper, it did offer an internal article written by director of compliance John DeLong, who’s is in charge of making sure NSA protects Americans’ privacy.
DeLong writes that privacy protections are being written into the technology that sifts the information, “which allows us to augment — not wholly replace — human safeguards.”
The NSA also uses “technology to record and review our activities. ... Sometimes, where appropriate, we even embed legal and policy guidance directly into our IT architecture.”
What that means is that the data sifting is mostly done not by humans, but by computers, following complicated algorithms telling them what to look for and who has a right to see it, according to Ronald Marks, a former CIA official.
“Through software, you can search for key words and key phrases linking a communication to a particular group or individual that would fire it off to individual agencies that have interest in it,” just like Amazon or Google scans millions of emails and purchases to track consumer preferences, explained Marks, author of “Spying in America in the Post 9/11 World.”
Detailed algorithms try to determine whether something is U.S. citizen-related or not. “It shows analysts, ‘we’ve got a US citizen here, so we’ve got to be careful with it,’” he said.
But the process isn’t perfect, and sometimes what should be private information reaches agencies not authorized to see it.
In that case, there are policies in place to “destroy that kind of information not file it or keep it if an American’s name coincidentally or serendipitously comes up,” John Negroponte, the first director of national intelligence, said in an Associated Press interview Friday.
Marks said that “when information gets sent to the CIA that shouldn’t, it gets destroyed, and a note sent back to NSA saying, ‘You shouldn’t have sent that.’” He added, “Mistakes get made, but my own experience on the inside of it is, they tend to be really careful about it.”
Michael Hayden, who led both the NSA and CIA, said the government doesn’t touch the phone records unless an individual is connected to terrorism.
He described on “Fox News Sunday” how it works if a U.S. intelligence agent seized a cellphone at a terrorist hideout in Pakistan.
“It’s the first time you’ve ever had that cellphone number. You know it’s related to terrorism because of the pocket litter you’ve gotten in that operation,” Hayden said.
“You simply ask that database, ‘Hey, any of your phone numbers in there ever talked to this phone number in Waziristan?’”
Hayden said the Obama administration had expanded the scope of the surveillance, but that oversight by lawmakers and the Foreign Intelligence Surveillance Court also had grown because of changes in the law.
The NSA was founded in 1952, but only years later was it publicly acknowledged, which explains the nickname, “No Such Agency.”
The agency also includes the Central Security Service, the military arm of code-breakers who work jointly with the agency. The two services have their headquarters on a compound that’s technically part of Fort Meade, though it’s slightly set apart from the 5,000-acre Army base.
Visible from a main highway, the tightly guarded compound requires the highest of clearances to enter and is equipped with electronic means to ward off an attack by hackers.
Other NSA facilities in Georgia, Texas, Colorado and Hawaii duplicate much of the headquarters’ brain and computer power in case a terrorist attack takes out the main location, though each one focuses on a different part of the globe.
