Help EFF Research Web Browser Tracking

Posted on January 27, 2010July 3, 2025 by Dissent

Data Privacy Day is tomorrow. Wouldn’t it be a good activity to take part in an experiment on how your online patterns can identify you? Peter Eckersley explains:

What fingerprints does your browser leave behind as you surf the web?

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. But how effective would this kind of online tracking be?

EFF is running an experiment to find out. Our new website 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 five million other configurations. Then, it will give you a uniqueness score — letting you see how easily identifiable you might be as you surf the web.

Adding your information to our database will help EFF evaluate the capabilities of Internet tracking and advertising companies, who are already using techniques of this sort to record people’s online activities. They develop these methods in secret, and don’t always tell the world what they’ve found. But this experiment will give us more insight into the privacy risk posed by browser fingerprinting, and help web users to protect themselves.
