Is Facebook using your computer camera to read your facial expressions and determine how you feel about what you see on your screen? Is it using your phone’s microphone to eavesdrop on you and find out what television programs you watch? Is it tracking your phone’s location in the middle of the night to find out where you live?
Maybe not, or at least not yet. But the company has applied for patents to do all these things, and many others, all of them intended to study your behavior and personality and even predict your future, in order to better serve Facebook’s customers. You may think that’s you, but it’s actually Facebook’s advertisers, which account for 99 percent of its revenue.
