Is Big Data turning government into 'Big Brother'?
June 8, 2013 | 1:08pm
SAN FRANCISCO — With every phone call they make and every Web excursion they take, people are leaving a digital trail of revealing data that can be tracked by profit-seeking companies and terrorist-hunting government officials.
The revelations that the National Security Agency is perusing millions of U.S. customer phone records at Verizon Communications and snooping on the digital communications stored by nine major Internet services illustrate how aggressively personal data is being collected and analyzed.
Verizon is handing over so-called metadata, excerpts from millions of U.S. customer records, to the NSA under an order issued by the secretive Foreign Intelligence Surveillance Court, according to a report in the British newspaper The Guardian. The report was confirmed Thursday by Democratic Sen. Dianne Feinstein, who chairs the Senate Intelligence Committee.
Former NSA employee William Binney told The Associated Press that he estimates the agency collects records on 3 billion phone calls each day.
The NSA and FBI appear to be looking even wider under a clandestine program code-named "PRISM" that was revealed in stories posted late Thursday by The Washington Post and The Guardian.
PRISM gives the U.S. government access to email, documents, audio, video, photographs and other data belonging to foreigners on foreign soil who are under investigation, according to The Washington Post. The newspaper said it reviewed a confidential roster of companies and services participating in PRISM. The companies included AOL Inc., Apple Inc., Facebook Inc., Google Inc., Microsoft Corp., Yahoo Inc., Skype, YouTube and Paltalk.
In statements, Apple, Facebook, Google, Microsoft, Yahoo, AOL and Paltalk all said they only provide the government with user data required under the law. (Google runs YouTube and Microsoft owns Skype.)
The NSA isn't getting customer names or the content of phone conversations under the Verizon court order, but that doesn't mean the information can't be tied to other data coming in through the PRISM program to look into people's lives, according to experts.
Like pieces of a puzzle, the bits and bytes left behind from people's electronic interactions can be cobbled together to draw conclusions about their habits, friendships and preferences using data-mining formulas and increasingly powerful computers.
It's all part of a phenomenon known as "Big Data," a catchphrase increasingly used to describe the science of analyzing the vast amount of information collected through mobile devices, Web browsers and check-out stands. Analysts use powerful computers to detect trends and create digital dossiers about people.
The Obama administration and lawmakers privy to the NSA's surveillance say the data being collected is only dissected when there is credible evidence of a terrorist plot or other reasons to believe that national security is being threatened. The sweeping court order covers the Verizon records of every mobile and landline phone call from April 25 through July 19, according to The Guardian.
