Your Results

Within our dataset of several hundred thousand visitors tested in the past 45 days, only one in 92701.0 browsers have the same fingerprint as yours.

Currently, we estimate that your browser has a fingerprint that conveys 16.5 bits of identifying information.

The measurements we used to obtain this result are listed below. You can read more about our methodology, statistical results, and some defenses against fingerprinting here.

Detailed Results

Here’s some more granular information we gathered about your browser. Your report includes examples of several different kinds of metrics:

Web Headers

Whenever you connect to a website (in our case, “https://coveryourtracks.eff.org”), your device sends a request that includes HTTP headers. These headers contain information like your device’s timezone, language, privacy settings, and cookies. Web headers are transmitted by your browser with every site visit.

JavaScript-derived Characteristics

Some details about your browser can be discovered by using JavaScript code. This includes fonts, certain details about your hardware configuration, and your canvas fingerprint.
