Internet anonymity test helps you to control your onlineprivacy and anonymity.
This site analyzes the privacy of your Internet connection and shows what your browser reveals when you visit a website. Modern web browsers provide a user with a lot of features but they have also been designed to reveal your IP address and tons of other "innocent looking" information to websites. A collection of such information can be used to compile browser fingerprints that according to the EFF study are unique and identifiable.
