[Cryptography] Anonymous online? A third of popular websites are ‘fingerprinting’ you.

[John Denker]

> At least a third of the 500 sites Americans visit most often use 
> hidden code to run an identity check on your computer or phone.
> 
> It doesn’t matter whether you turn on “private browsing” mode, clear 
> tracker cookies or use a virtual private network. Some even use the 
> fact you’ve flagged “do not track” in your browser as a way to 
> fingerprint you.

> it is still possible to make yourself hard to fingerprint by using
> software such as Tor. It’s a privacy-first browser that goes to great
> lengths to make each user’s device look the same — but only useful
> for highly technical people because it breaks common websites.
