I’m not surprised that Facebook collects data of more than a billion users exactly like any other companies, but the statement hides many pitfalls because the company will to deliver ‘targeted Ads’ on its service have to keep note of the overall user web experience.
Facebook, to provide targeted ads, needs to track every website the user visits, even if it isn’t Facebook website.
“Today, we learn about your interests primarily from the things you do on Facebook, such as Pages you like. Starting soon in the US, we will also include information from some of the websites and apps you use. This is a type of interest-based advertising, and many companies already do this.“
“We and our affiliates, third parties, and other partners (“partners”) use these technologies for security purposes and to deliver products, services and advertisements, as well as to understand how these products, services and advertisements are used. With these technologies, a website or application can store information on your browser or device and later read that information back.”
- If you own an iphone, open settings and go to General->Restrictions->Advertising, and then click “Limit Ad Tracking.”
- If you own an Android Smartphone, go to Google Settings->Ads->Opt Out of Interest-Based Ads and click, you are done.
The defense policy will be increasingly difficult, but know who and how handles our data is crucial.
