Vast Benefits, Vast Risks

Microsoft research head Eric Horvitz believes that computers will be able to tell if you're sick. They will know this before you do and before you ask them to look. [bold added]

He and Microsoft colleague Ryen White, along with co-investigators from Stanford and other universities, have examined anonymized data from hundreds of millions of users of Bing, Microsoft’s search engine. They initially looked at query terms—what you search for—and the time and date of searches. Then, they added IP addresses—your computer’s unique identifier—and other location information. Most recently, they have focused on motor movements such as keystrokes, clicks and mouse activity.

This data can reveal critical diagnostic evidence. People confide intimate secrets about their health—yellow skin, odd-looking stools and other curious symptoms—to their search engine that they do not share with others, even physicians, Horvitz says. And the biometric and geographic information picked up by search engines may uncover secrets of which even users are unaware.

Just because someone did a web search on symptoms doesn't mean that he or she has cancer, but that datum can be correlated with other information, for example, if the user comes from a region with a high incidence of cancer. Similarly, a change in mouse-click speed and accuracy may indicate sleeplessness or a budding neurodegenerative condition, relatively easy to determine from other indicia (age, family history, whether the cellphone was active at 3 a.m., etc.)

We're not there yet, but we're nearing the point when computer networks will know each individual better than they know themselves. The benefits are vast, but so are the risks.

Sodden afterthought--if the Graduate were remade today, the dialogue might well go something like this:

MR. MCGUIRE: I want to say two words to you. Just two words.

BENJAMIN: Yes, sir.

MR. MCGUIRE: Are you listening?

BENJAMIN: Yes, I am.

MR. MCGUIRE: Predictive analytics.
