I just happened to wonder how easy or difficult it is to find who I am, using information security's most advanced techniques. And what can I do that will not affect my browsing experience too much, as a lambda internet user, against that  ?

Sorry if that is not the best place to ask, and maybe I am wrong, but this seems the best community from stack exchange about such problems.

Thanks in advance.
