What does Facebook know about you?

Social networking is still one of the most used applications, a place to connect friends and family as well as find people with similar interests.Born in 2004, Facebook is now the leader in the social networking world with 2.23 billion users worldwide.

The more popular, the more Facebook has attracted many users and become more popular.But before you open the phone, select 'Agree' to allow the app to do what it needs to do, see what Facebook gathers about the user to make the right decision.

1. These are all the data about you that the websites you visit collect
2. What is Social Networking?

Credit

This should not be surprising because there may be times when you have bought goods on Facebook, be it games, event tickets or charity fundraising.Because it was done via credit card, Facebook also saved the information, although it should not seem to be a problem, but users also have to think when hearing the news such as the recent Facebook hack revealed information of 30 million. user.

Facebook can also store information about these purchases, track how you detail and create another profile of your financial spending.

Think carefully before providing credit card information

Phone data

Facebook is increasingly popular on mobile phones, with about 63% of users accessing by phone.And also because it is downloaded to the phone, it can't help but peek at the user's phone data.

Most of us see no problem when Facebook views contacts to find friends, extending circles on Facebook.But many users do not realize that Facebook looks even more.For example, Android has reported that Facebook accesses the call history of users, each call for years.

Facebook apps also collect SMS data, using algorithms to determine what business contacts are.Any information about that phone book, call history or SMS message is not listed in the data list they collect.

Personalize ads

In the recent analysis, Facebook also followed Google's advertising monetization model.And these ads will achieve better results when they understand their audience.So Facebook constantly counts what you like / dislike.

For example, if you like a certain political character, Facebook says it will not sell information directly, but will allow advertisers to advertise based on what they know about your interests.

Because advertising revenue is very important, they also use other demographic data such as age, gender . to provide relevant advertising.They also navigate based on the ads you clicked on, or your posts or posts you like.

Anyway, compared to non-targeted random ads, it is much better to bring ads to the right people.

Facebook knows who you are

Part of creating a Facebook profile is posting an avatar so others can recognize you.Those with popular names will also make it easier for friends to find their Facebook page.

But Facebook goes even further by using face-detection software made by AI, gathering into a large database, so that users are automatically tagged into other people's photos.

Who are you, what do you do, where are you . Facebook knows all

Because of this, earlier this year, a class action lawsuit accused Facebook that they (users) did not agree to allow Facebook to perform face detection, creating or storing their faces.Again, Facebook ignores mentioning that they store user face templates.

Facebook remembers it all

While many people don't remember what I ate this morning, Facebook remembers everything.They know exactly when you created your account, make friends / unfriend who, all the posts / photos you posted.They know what school you study, where you work, what your marital status is.

If those things are not scary enough, according to the terms at Facebook Location Services, they know exactly where you are and where you go.We can choose otherwise, but most let 'Big Brother Facebook' go on every step we take.
