Fingerprint
From Freephile Wiki
Online privacy is dead.
We are tracked and under surveillance like never before.
See EFF's tool which can tell you more about your browser security and learn how you may likely have a digital fingerprint which identifies you despite not being tracked in more traditional ways. https://panopticlick.eff.org/
They also offer an example of a Privacy-friendly "Do Not Track" policy https://www.eff.org/dnt-policy
