Facebook Filed a Patent To Predict Your Household's Demographics Based On Family Photos (buzzfeednews.com) 98
It would note the people identified in a photo, and how frequently the people are included in your pictures. Then, it would assess information from comments on the photos, captions, or tags (#family, #mom, #kids) -- anything that indicates whether someone is a husband, daughter, cousin, etc. -- to predict what your family/household actually looks like. According to the patent application, Facebook's prediction models would also analyze "messaging history, past tagging history, [and] web browsing history" to see if multiple people share IP addresses (a unique identifier for every internet network). A Facebook spokesperson said in response to the story, "We often seek patents for technology we never implement, and patents should not be taken as an indication of future plans."
