NEW YORK: The Facebook scandal that involved the collection of data from tens of millions of users generated many questions about social networks and search engines.
As the founder and CEO of Facebook, Mark Zuckerberg, testified before the US Congress. UU On the protection of user data, here is an introduction to what they know about you:
Social media
Facebook, which has more than two billion users, has access to everything you do on the site: the photos and videos you post, your comments, your "likes", whatever you share or consult, the identity of your Friends and any other user you interact with, your location and other information.
Ditto for Instagram and WhatsApp, which are owned by Facebook, and for Snapchat and Twitter.
A user can control sharing their Facebook data with the privacy settings and the ads preferences page.
What sells: Facebook insists that it does not sell personally identifiable information to advertisers or even add data. What an advertiser offers is the ability to reach a specific demographic group, which improves the effectiveness of an advertising campaign. Twitter, on the other hand, provides access to an internal search engine that sweeps all messages on the site.
What it shares: Most social media platforms are open to external developers who create applications powered to varying degrees by using data from users of these networks. In the case of Facebook, the public profile - the full page for some people, or just the first and last name and the photo for others - does not require the user's authorization, but accessing the rest may require a separate authorization from the user.
Once the external applications extract the data, they are no longer available to Facebook and it is difficult to try to recover them again.
"Once people had access to that information, Facebook has no way of knowing for sure what they did with that information," said Ryan Matzner, co-founder of mobile application designer Fueled. "It's like sending an email to someone and then saying, 'What did they do with that email?' You do not know ".
Only the bank and payment data of Facebook are out of bounds.
The search engines
What they collect: Google, Yahoo and Bing collect all the information that includes searches, including the websites that are accessed and the user's location. This can be integrated with the information of other services owned by the Internet giants.
"You do not have to tell Google your age, your gender and all those things, they can determine all of that based on many other factors," said Chirag Shah, a professor of computer science at Rutgers University.
What they sell: like social networks, their income comes mainly from advertising. They do not sell data, but have access to a consumer with very specific characteristics.
This comes from the collection of data from the search engine, but also, in the case of Google, the searches and the content displayed on your YouTube platform. Google used to extract Gmail content before ending this practice in June.
What they share: Like social networks, search engines share data with developers and manufacturers of third-party applications.
Are there limits?
In the United States there are practically no laws against the use of data from social networks or search engines.
But the Federal Trade Commission sanctioned Facebook in 2011 for its handling of personal data.
In Canada and Europe, there are some limits on the use of data, mainly related to health.
Last year, the European Commission fined Facebook a fine of 110 million euros (135.7 million dollars) for sharing personal data with WhatsApp.
In an attempt to harmonize data privacy laws, the EU General Data Protection Regulation will enter into force on May 25.
