The National Security Agency is collecting millions of images of
people through its international surveillance network to be implemented
in a number of other facial recognition programs, according to documents
leaked by Edward Snowden.

Thanks to rapid advances being made in the field of facial
recognition technology, the NSA is much better equipped to
“exploit the flood of images included in emails, text
messages, social media, video conferences and other
communications,” according to an article in the New York
Times, co-written by Laura Poitras, who, together with Glen
Greenwald, are the only two journalists to have received the
leaked NSA documents.
The NSA has the capacity to intercept
“millions of images per
day,” as well as some 55,000
“facial recognition quality
images.” This latest milestone in US intelligence gathering,
which goes a long way to putting the final touches on the
much-feared Orwellian nightmare, gives the US spy agency
“tremendous untapped potential,” according to the 2011
documents.
“It’s not just the traditional communications we’re after:
It’s taking a full-arsenal approach that digitally exploits the
clues a target leaves behind in their regular activities on the
net to compile biographic and biometric information” that can
help “implement precision targeting,” noted a document dated 2010.

Such comments are bound to spark fears that the harvesting of
facial images, much like the collection of oral and written
communications, will snag innocent Americans in the vast
intelligence net.
The latest revelations to be gleaned from Snowden’s stash of
top-secret documents prove the NSA is not just interested in
collecting the meta-data from global communications, but also the
images that put a face on potential terrorists and other would-be
adversaries of the American government.
The NSA is unique in its ability to match images with huge troves
of private communications.
“We would not be doing our job if we didn’t seek ways to
continuously improve the precision of signals intelligence
activities — aiming to counteract the efforts of valid foreign
intelligence targets to disguise themselves or conceal plans to
harm the United States and its allies,” said Vanee M. Vines,
the agency spokeswoman.
ID databases out of the game?
Since most people have a number of photographs taken of
themselves for identification purposes, the question arises as to
how much reach the NSA has in acquiring peoples’ facial images.
According to Vines, the NSA does not access driver’s licenses or
passport photos of Americans, but refused to say whether the
agency had access to the State Department’s photo archive of
foreign visa applicants. She also declined to say whether the spy
agency collected photographs of Americans from social media
sources, like Facebook and Instagram, which would not be a
difficult task considering that millions of people willingly post
‘selfies’ to the web.
Moreover, the report claimed that one of the agency’s most
intense efforts to acquire facial images is through a program
dubbed Wellspring, which “strips out images from emails and other
communications, and displays those that might contain passport
images.”

Because images are considered a form of communicational content,
the NSA is required to get court approval for collecting facial
images of Americans, just as it is required to read emails or
listen in on phone conversations, an NSA spokeswoman was quoted
in the Times article as saying.
However, exceptions may be made in the event
“an American
might be emailing or texting an image to someone targeted by the
agency overseas,” it said.
Human rights and civil liberty groups are expressing concern that
the power of the technology, in the hands of government and
corporate officials, could have a disastrous impact on privacy.
“Facial recognition can be very invasive,” Alessandro
Acquisti, a researcher on facial recognition technology at
Carnegie Mellon University in Pittsburgh, told the paper.
“There are still technical limitations on it, but the
computational power keeps growing, and the databases keep
growing, and the algorithms keep improving.”
Harvesting on video conferences
The NSA facial recognition program made tremendous headway in
2010 when it successfully matched images from two separate
databases, one in the NSA database code-named Pinwale, and
another in the government’s primary terrorist watch database,
known as Tide, the NSA files revealed.
That technical breakthrough led to an
“explosion of
analytical uses” for the agency.
The NSA has since brought on board “identity intelligence”
analysts whose job it is to match the facial images with other
records about individuals to build broad portfolios of
intelligence targets.
The full depth of the image-collection program is daunting in
that it has developed sophisticated methods of integrating facial
recognition programs with numerous other databases.

“It intercepts video teleconferences to obtain facial
imagery, gathers airline passenger data and collects photographs
from national identity card databases created by foreign
countries, the documents show,” the files revealed.
They also show that the NSA was attempting to infiltrate such
databases in Pakistan, Saudi Arabia and Iran.
Aside from its own programs, the NSA partially relies on
commercially available facial recognition technology, including
from PittPatt, a company owned by Google, the leaked files show.
Geo-positioning does matter
But the power of facial recognition technology apparently goes
beyond the collection of faces, and includes geographic points
photographed from satellites.
One leaked file shows photographs of several men standing near a
waterfront dock in 2011. Through the use of the recognition
technology, the NSA was able to match their surroundings to a
satellite image of the same dock taken about the same time.
The document said the photograph showed a militant training
facility in Pakistan.
Meanwhile, US law remains surprisingly flimsy in terms of the
protections it offers Americans when it comes to their images.
“Unfortunately, our privacy laws provide no express
protections for facial recognition data,” said Senator Al
Franken, Democrat of Minnesota, in a letter in December to the
head of the National Telecommunications and Information
Administration.
News of the NSA’s ‘facial-mining’ techniques echo earlier leaked
information, reported in February, that Britain's spy agency
GCHQ, in direct cooperation with the NSA, intercepted and stored
the webcam images of millions of internet users not suspected of
terrorism or other criminal behavior.
GCHQ records between 2008 and 2010 reveal a surveillance program,
codenamed Optic Nerve, harvested still images of Yahoo webcam
chats and stored them on databases, the Guardian reported.
“In one six-month period in 2008 alone, the agency collected
webcam imagery – including substantial quantities of sexually
explicit communications – from more than 1.8 million Yahoo user
accounts globally,” the paper reported.
