Facebook knows how many times you have searched your ex-partner's profile (but you can delete that information)

Facebook is being forced to explain how much information it collects about us and for what. After thousands of questions from the Senate and the US Chamber, we have a 225-page document that includes these questions and the company's answers, presented a couple of months ago.

For example, the senator from California, Kamala Harris, asked in detail about the extent of Facebook's data collection. We discovered that they even know how many times we have re-entered the profile of our ex-partner, in addition to other data that sound like a dystopian nightmare.

How do you move the mouse

Facebook not only knows who we are looking for and saves all that information, but it knows how many times we visit that profile, if we are looking closely at the screen or it is in the background, even how we move the mouse over the page.

And all this information can reveal many things of the user. Recently, for example, researchers from the Autonomous University of Madrid have developed SentBuck, an application that deduces the mood of Facebook users through the algorithmic analysis of their messages.

There are good news: you can delete any search query you want, although the registration will take about six months to disappear completely, according to Facebook. Simply go to the "Activity Log" on your profile page and click on "Search History". Next to each query, there is an option to delete it.

Technically, no one can see this information except yourself, but prevention is better than cure, right? However, it seems that our information will continue to flow, and we will be part of the Social Big Data that will change everything shortly. Viktor Mayer-Schonberger and Kenneth Cukier in the Big Data book abound in what is to come:

The next frontiers of dating are more personal: our relationships, experiences and moods. (...) These uses of the data are still in an embryonic state (...) The potential uses are extraordinary. A number of start-up companies have studied adapting the social graph to use it as signals that allow establishing credit ratings. The idea is that "God raises them and they get together": prudent people make friends with similarly minded people, while wasteful people incur non-payment together. If it goes well, Facebook could become the next FICO, the credit rating agency.
