Surveillance by Algorithm

Increasingly, we are watched not by people but by algorithms. Amazon and Netflix track the books we buy and the movies we stream, and suggest other books and movies based on our habits. Google and Facebook watch what we do and what we say, and show us advertisements based on our behavior. Google even modifies our web search results based on our previous behavior. Smartphone navigation apps watch us as we drive, and update suggested route information based on traffic congestion. And the National Security Agency, of course, monitors our phone calls, emails and locations, then uses that information to try to identify terrorists.

Documents provided by Edward Snowden and revealed by the Guardian today show that the UK spy agency GHCQ, with help from the NSA, has been collecting millions of webcam images from innocent Yahoo users. And that speaks to a key distinction in the age of algorithmic surveillance: is it really okay for a computer to monitor you online, and for that data collection and analysis only to count as a potential privacy invasion when a person sees it? I say it’s not, and the latest Snowden leaks only make more clear how important this distinction is.

The robots-vs-spies divide is especially important as we decide what to do about NSA and GCHQ surveillance. The spy community and the Justice Department have reported back early on President Obama’s request for changing how the NSA “collects” your data, but the potential reforms — FBI monitoring, holding on to your phone records and more — still largely depend on what the meaning of “collects” is.

Indeed, ever since Snowden provided reporters with a trove of top secret documents, we’ve been subjected to all sorts of NSA word games. And the word “collect” has a very special definition, according to the Department of Defense (DoD). A 1982 procedures manual (pdf; page 15) says: “information shall be considered as ‘collected’ only when it has been received for use by an employee of a DoD intelligence component in the course of his official duties.” And “data acquired by electronic means is ‘collected’ only when it has been processed into intelligible form.”

Director of National Intelligence James Clapper likened the NSA’s accumulation of data to a library. All those books are stored on the shelves, but very few are actually read. “So the task for us in the interest of preserving security and preserving civil liberties and privacy,” says Clapper, “is to be as precise as we possibly can be when we go in that library and look for the books that we need to open up and actually read.” Only when an individual book is read does it count as “collection,” in government parlance.

So, think of that friend of yours who has thousands of books in his house. According to the NSA, he’s not actually “collecting” books. He’s doing something else with them, and the only books he can claim to have “collected” are the ones he’s actually read.

This is why Clapper claims — to this day — that he didn’t lie in a Senate hearing when he replied “no” to this question: “Does the NSA collect any type of data at all on millions or hundreds of millions of Americans?”
