How to prevent Facebook data from being shared with other apps

Facebook allows you to change the privacy and information given to third-party applications to protect data on the social network. The alternative has been sought by users following a scandal involving the social network in the last week. Investigation of US newspapers revealed that the information of over 50 million people was misused.

To make the data informed to the social network more secure, see how to delete apps, change privacy, and avoid having your information shared with third-party sites.

Preventing online testing from using personal data on Facebook

Data from 50 million Facebook users were obtained and used illegally

Understand the case

According to reports in The Gardian and New York Times, consulting firm Cambridge Analytica used data from 50 million people illegally obtained from the 2016 US presidential campaign.

These data were collected through a psychological test - in the same style as "What Celebrity Do You Look Like ?, " which was successful in Brazil. To test, the user had to authorize the application to see some information from their Faceboook profile.

Called "thisisyourdigitallife", the app was designed by researcher Aleksandr Kogan. In total, 270, 000 users have access to their data on Facebook and also the information of all the friends on the platform, totaling 50 million people.

Kogan was responsible for providing the information to Cambridge Analytica. The company was hired for campaign candidate Donald Trump. According to investigations in the US press, the consultancy would have used the data obtained by Facebook to create strategies (including rumors, false news and misinformation) and influence voters. The researcher would have sold the data for $ 800, 000.

According to Facebook, social network policy allows developers to access data only for the purpose of improving the application experience. The sale of this information or use for advertising is prohibited.
