Facebook, like Google, can also guess when you will die

Some of Facebook's patents involve tracking your sleeping hours, identifying friends you hang out with, and guessing when you'll die.

Reading the user’s relationships

One patent talks about predicting if the user is in a romantic relationship based on the number of times they visit another user’s page, the number of people in their profile picture, and the percentage of friends they have who are of a different gender.

Classifying the user’s personality

Another patent attempts to understand the user’s personality based on their posts and messages to serve them more relevant stories or ads. It attempts to judge the user’s degree of extroversion and emotional stability.

Predicting the user’s future

This patent proposes to predict major events in the user’s life like marriage, graduation, childbirth and death by analysing credit card transactions and location information, in addition to the user’s posts and messages.

Identifying the user’s camera

There’s one patent that talks about identifying the user’s camera by creating a unique camera ‘signature’ for every user, using faulty pixels or scratch marks on the lens. By knowing who uploads pictures taken through these cameras, the relationship or ‘affinity’ between the uploader and the camera user can be guessed.

Listening to the user’s environment

Another patent proposes listening in on the user’s surroundings to understand which TV shows are watched and which ads are muted. It also proposes guessing the name of the TV show by using the electrical interference pattern caused by the television’s power cable.

Tracking the user’s routine

One more patent application talks about tracking the user’s weekly routine and sending notifications of any deviations in it to other users. It also talks about determining the user’s home address by reading location information in the middle of the night.

Understanding the user’s habits

This patent proposes using the user’s location along with their friends’ location to determine whom the user socialises most with. It also proposes tracking the number of hours the phone is stationary to count sleeping hours.

According to The New York Times, Allen Lo, a Facebook Vice President said in an email, “Most of the technology outlined in these patents has not been included in any of our products, and never will be.”
