We are used to the fact that things are free on the web. Since the Snowden case, more people know that even free services have their price. In spite of this, most of us still don't take any countermeasures to protect their privacy. But is it hard to protect our online activities? Or is this battle already lost? The first part of this talk will be an overview of the history of web privacy, how and why our online presence is exploited in exchange of getting some services for free. In the second part, we will discuss fingerprinting, a tracking method in details, and see how the underlying problem of identification relates to other platforms such as smartphones or location privacy.
