Facebook has filed thousands of patent applications since it went public in 2012. One of them describes using forward-facing cameras to analyze your expressions and detect whether you’re bored or surprised by what you see on your feed. Another contemplates using your phone’s microphone to determine which TV show you’re watching. Others imagine systems to guess whether you’re getting married soon, predict your socioeconomic status and track how much you’re sleeping.

A review of hundreds of Facebook’s patent applications reveals that the company has considered tracking almost every aspect of its users’ lives: where you are, who you spend time with, whether you’re in a romantic relationship, which brands and politicians you’re talking about. The company has even attempted to patent a method for predicting when your friends will die.

Facebook has said repeatedly that its patent applications should not be taken as indications of future product plans. “Most of the technology outlined in these patents has not been included in any of our products, and never will be,” Allen Lo, a Facebook vice president and deputy general counsel, and the company’s head of intellectual property, said in an email.

Taken together, Facebook’s patents show a commitment to collecting personal information, despite widespread public criticism of the company’s privacy policies and a promise from its chief executive to “do better.”

“A patent portfolio is a map of how a company thinks about where its technology is going,” said Jason M. Schultz, a law professor at New York University.

Here are seven Facebook patent applications that show how the company has contemplated gathering and exploiting your personal information.

In some cases, companies file patents defensively, to beat their rivals to a new technology, even if they have no intention of using it. While that could be the case for some of Facebook’s patents, many of them imagine new ways to collect, analyze and use personal information and package it for advertisers — a process that is essential to the company’s business model. In the first quarter of 2018, almost 99 percent of Facebook’s revenue came from advertising.

As long as Facebook keeps collecting personal information, we should be wary that it could be used for purposes more insidious than targeted advertising, including swaying elections or manipulating users’ emotions, said Jennifer King, the director of consumer privacy at the Center for Internet and Society at Stanford Law School. “There could be real consequences,” she said.

Other technology companies have filed unsettling patent applications, too. They include Amazon’s wristbands for tracking warehouse employees and the Google teddy bear equipped with a camera and a microphone.

But with more than two billion monthly active users, most of whom share their thoughts and feelings on the platform, Facebook is amassing our personal details on an unprecedented scale. That isn’t likely to change, said Siva Vaidhyanathan, a professor of media studies at the University of Virginia. “I’ve seen no indication that Facebook has changed its commitment to watch everything we do, record everything we do and exploit everything we do,” he said.
