NSA Doesn’t Need to Spy on Your Calls to Learn Your Secrets



GOVERNMENTS AND CORPORATIONS gather, store, and analyze the tremendous amount of data we chuff out as we move through our digitized lives. Often this is without our knowledge, and typically without our consent. Based on this data, they draw conclusions about us that we might disagree with or object to, and that can impact our lives in profound ways. We may not like to admit it, but we are under mass surveillance.



Much of what we know about the NSA’s surveillance comes from Edward Snowden, although people both before and after him also leaked agency secrets. As an NSA contractor, Snowden collected tens of thousands of documents describing many of the NSA’s surveillance activities. Then in 2013 he fled to Hong Kong and gave them to select reporters.Click to Open Overlay GalleryExcerpted from Data and Goliath: The Hidden Battles to Collect Your Data and Control Your World


The first news story to break based on the Snowden documents described how the NSA collects the cell phone call records of every American. One government defense, and a sound bite repeated ever since, is that the data they collected is “only metadata.” The intended point was that the NSA wasn’t collecting the words we said during our phone conversations, only the phone numbers of the two parties, and the date, time, and duration of the call. This seemed to mollify many people, but it shouldn’t have. Collecting metadata on people means putting them under surveillance.

An easy thought experiment demonstrates this. Imagine that you hired a private detective to eavesdrop on someone. The detective would plant bugs in that person’s home, office, and car. He would eavesdrop on that person’s phone and computer. And you would get a report detailing that person’s conversations.

Now imagine that you asked the detective to put that person under surveillance. You would get a different but nevertheless comprehensive report: where he went, what he did, who he spoke to and for how long, who he wrote to, what he read, and what he purchased. That’s metadata.
Eavesdropping gets you the conversations; surveillance gets you everything else.

One experiment from Stanford University examined the phone metadata of about 500 volunteers over several months. The personal nature of what the researchers could deduce from the metadata surprised even them, and the report is worth quoting:
Telephone metadata alone reveals a lot about us. The timing, length, and frequency of our conversations reveal our relationships with each other: our intimate friends, business associates, and everyone in-between. Phone metadata reveals what and who we’re interested in and what’s important to us, no matter how private. It provides a window into our personalities. It provides a detailed summary of what’s happening to us at any point in time.

Google knows what kind of porn each of us searches for, which old lovers we still think about, our shames, our concerns, and our secrets. If Google decided to, it could figure out which of us is worried about our mental health, thinking about tax evasion, or planning to protest a particular government policy. I used to say that Google knows more about what I’m thinking of than my wife does. But that doesn’t go far enough. Google knows more about what I’m thinking of than I do, because Google remembers all of it perfectly and forever.

If you have a Gmail account, you can check for yourself. You can look at your search history for any time you were logged in. It goes back for as long as you’ve had the account, probably for years. Do it; you’ll be surprised. It’s more intimate than if you’d sent Google your diary. And while Google lets you see it, you have no rights to delete anything you don’t want there.

There are other sources of intimate data and metadata. Records of your purchasing habits reveal a lot about who you are. Your tweets tell the world what time you wake up in the morning, and what time you go to bed each night. Your buddy lists and address books reveal your political affiliation and sexual orientation. Your email headers reveal who is central to your professional, social, and romantic life.
