10.1. Does the browser option “Do not track” help?
Not really. Companies routinely ignore “do not track” (DNT) requests. In fact, since most users do not select DNT, selecting the DNT makes it easier to identify you. This is the reason Apple gave for removing the feature from its browsers.
A German court recently ruled against LinkedIn for ignoring DNT. Maybe this will result in more companies honoring it. Or maybe the LinkedIn case is the exception that proves the rule: it is so common to get away with ignoring DNT that it’s newsworthy when a company is held accountable.
10.2. What is browser fingerprinting?
The information about a computer revealed by a web browser – the fonts installed, the operating system version, the browser version – is often unique. Fonts alone are usually enough to uniquely identify a browser. See this article for more on font fingerprinting.
10.3. Does Tor protect your identity?
It didn’t protect the identity of Ross William Ulbricht who used the pseudonym Dread Pirate Roberts on the Silk Road network.
