Traditionally, people assume they can prevent a website from identifying them by disabling cookies on their web browser. Unfortunately, this is not the whole story.

When you visit a website, you are allowing that site to access a lot of information about your computer's configuration. Combined, this information can create a kind of fingerprint - a signature that could be used to identify you and your computer. Some companies are already using technology to try to identify individual computers. But how effective would this kind of online tracking be?

EFF is running an experiment to find out. Panopticlick will anonymously log the configuration and version information from your operating system, your browser, and your plug-ins, and compare it to our database of many other Internet users' configurations. Then, it will give you a uniqueness score - letting you see how easily identifiable you might be as you surf the web.

The seems that the browser plugin details are the most dangerous.

EFF site - safe to test there.

Most of info is taken as always form java script(may be disabled).

User Agent Info also can be spoofed easily for example with Firefox addon(User Agent Switcher (http://chrispederick.com/work/user-agent-switcher/))

The easiest way to hide information about you is to use Virtual Machine or WMVare.

Virtualization is a large resource expense wouldn't you agree?
It is rather sandboxing in that case.

I took mine with javascript enabled.
Here's how it looks like without:

The proof that the noscript addon makes the difference.

Sandboxing may still let apps have access to the "real" system. But browsing inside a VM is resource-intensive.

These are the results I get using a hardened (http://www.sb-innovation.de/f69/good-firerfox-addons-2761/index2.html#post293980) Firefox:

I feel the first two could be less unique, but overall they're very good.
