“Your Facebook data are bought and sold daily”

When advertisers want to target a certain group of clients who, for example, are a given age and have a certain political connection or interest, Facebook has knowledge of this.

The states you share, Facebook packs together, and then these in the state some commercial companies.

On Facebook, you are the product. Advertisers are client, reports “CNN” Transmission Periscope.

It's not just Facebook. Most of the networks supported by advertisers sell some of your data to third parties. Google, Microsoft, Yahoo, AOL, Amazon, Titter and Yelp do the same.

Your data is the price we pay for taking free use of Facebook.

Most of the time, this exchange works: People benefit from free services by posting, seeking, and distributing.

Facebook and Google control three-quarters of the digital advertising market of 83 billion dollars in the United States, according to Marcheter.

Most companies offer privacy qualities, and some even let you go and get your data.

After sharing something in every digital service, your personal data leaves your control. Cambridge Analytica serves as a reminder of that.

Data scientist who collected information on millions of Americans for Cambridge Analytica, the controversial data firm that worked for Donald Trump's presidential campaign, says he would be happy to testify before Congress and talk to the FBI about the work he did for the company.

Alexander Kogan made remarks on an email he sent to Cambridge University colleagues this weekend received by “CNN”

The Kogan company had received data from millions of Americans since early 2014.

The data was collected through a personality test ? an installed Facebook app created by Kogan.

When Facebook users used this app, their data was placed on the Kogan app, including demographic information such as name, location, age, gender and information about society.

Facebook says that Kogan told them he was collecting data for academic purposes and that by providing data to Cambridge Analytica, he had violated Facebook policy.

On Friday, Facebook suspended the Kogan platform “Cambridge Analytica” The suspension came after recent reports from “The York Times” and the “The Observer” had assumed that Cambridge Analytica did not erase the data when she asked Facebook in 2015 while these assumptions were rejected by Cambridge Analytica.

“was a surreal week,” told his colleagues, Kogan. I'm seriously questioned by NY Times and Guardian reporters if I'm a Russian spy. If I'm a Russian house, I'm the dumbest house in the world. ”/Periscopi/
