Canvas Fingerprint Defender

Defending against Canvas fingerprinting by reporting a fake value.

Canvas Fingerprint Defender - Secure your Online Privacy

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.

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.

User reviews

If you are using Brave browser like I am this does more harm than good. Brave (and lots of other browsers) has built in randomization, so adding an extension just makes your fingerprint stand out. If you are unsure, you can test your results at coveryourtracks.com

I spent TWO DAYS debugging my project because of this extension! Every image I drew on a canvas it was getting random colour tints. I was about to throw my pc out the window. Turns out, Canvas Fingerprint Defender was the cause of the issue. Disabled it, and poof - problem solved. This extension might be fine for privacy, but the side effects should be mentioned clearly. Save yourself the headache and disable it while coding.
