Canvas Fingerprint Defender

Defending against Canvas fingerprinting by reporting a fake value.

What is Canvas Fingerprint Defender?

Canvas Fingerprint Defender is a lightweight Chrome extension designed to protect user privacy. It combats canvas fingerprinting, a common online tracking method, by reporting a random fake value instead of the real fingerprint. It's easy to use - just add to your browser and start browsing. This extension adds a small noise to the actual fingerprint and renews it every time a webpage is visited or refreshed. Tests can be conducted using websites that display your fingerprint, with every reload returning a fake fingerprint.

Summary

Analyze keywords

Canvas Fingerprint Defender is a lite extension that lets you easily hide your real canvas fingerprint by reporting a random fake value.

According to many tech blogs, completely blocking canvas fingerprints is not a good idea, therefore reporting a "fake" fingerprint could be the best solution to better protect your privacy. This addon simply adds a small noise to the actual fingerprint and "renews" it every time you visit a website or reload a page. It is important to note that, it does not have any settings or options to adjust. Simply add it to your browser and start surfacing the internet. If you want to test this addon, please visit a website that shows your fingerprint (i.e. browserleaks). Every time you reload the page, you will see a new fake fingerprint.

To report bugs, please visit the addon's homepage (https://mybrowseraddon.com/canvas-defender.html) and fill out the bug report form.

Can validate that it works and provides unique Canvas via EFF tool CoverYourTracks in addition to BrowserLeaks and AmIUnique. On developer site, there were some trackers but running pakcet and tracker tracing, there are none coming from the extension itself as is stated in the privacy policy. I was skeptical when I saw them come up from developer's website but was able to validate extension is 100% clean and does exactly what it is supposed to do.Only takes 15MB - 35MB of memory to run which in terms of Chrome and other Chromium based browsers, is a very low overhead for something adding another layer of privacy and security.
