“Metadata” Can Tell the Government More About You Than the Content of Your Phonecalls
by George Washington
The government has sought to “reassure” us that it is only tracking “metadata” such as the time and place of the calls, and not the actual content of the calls.
But technology experts say that “metadata” can be more revealing than the content of your actual phone calls.
For example, the ACLU notes:
A Massachusetts Institute of Technology study a few years back found that reviewing people’s social networking contacts alone was sufficient to determine their sexual orientation. Consider, metadata from email communications was sufficient to identify the mistress of then-CIA Director David Petraeus and then drive him out of office.
The “who,” “when” and “how frequently” of communications are often more revealing than what is said or written. Calls between a reporter and a government whistleblower, for example, may reveal a relationship that can be incriminating all on its own.
Repeated calls to Alcoholics Anonymous, hotlines for gay teens, abortion clinics or a gambling bookie may tell you all you need to know about a person’s problems. If a politician were revealed to have repeatedly called a phone sex hotline after 2:00 a.m., no one would need to know what was said on the call before drawing conclusions. In addition sophisticated data-mining technologies have compounded the privacy implications by allowing the government to analyze terabytes of metadata and reveal far more details about a person’s life than ever before.
