Metadata Protest
The National Security Agency's collection of metadata has prompted numerous protests. With the portion of the Patriot Act that allows the NSA program set to expire June 1, debate is heating up in Congress on whether the rule should be renewed. Getty Images

When the world learned about the two secret NSA surveillance programs -- the Verizon data collection and PRISM -- one word that got thrown around a lot was “metadata.” American citizens were told that the NSA only collects metadata, or “data about data,” from cell phone conversations, emails and chats, but what can the NSA actually learn from it?

Quite a bit, actually, as the MIT Media Lab's Immersion project shows. Immersion integrates with a personal Gmail account to create an interactive visualization of the user’s metadata, allowing you to effectively spy on yourself. While Immersion can’t know anything about the content of the emails, it creates a comprehensive and accurate representation of the user’s life. With my account, the most activity is between my former classmates at the Columbia Journalism School, as well as my former roommates and landlords. This makes sense as the two groups often overlapped. While I primarily use other accounts for professional emails, there are sections illustrating some contacts from work.

The Immersion project from MIT visualizes information the NSA can learn from programs like PRISM. Immersion

For each individual contact, you can see the first email to them, the last email, how many have been sent and received, and which were marked as private. It can also make a list of other people this contact introduced you to.

If this is everything the NSA can access for every person using Google, Facebook, Apple, Microsoft, Yahoo, Dropbox, Skype and Verizon, it is more than a bit frightening.
