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.

Extension summary

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.

Don't be mislead by the sophist comments! Despite an "update" in April 2023, this date doesn't represent an update. It means Google's terms have been updated. Check your old version and the latest, it'll be the same. This extension doesn't do anything. Don't let the sophists mislead you further. I confirmed with many different fingerprinting sites . To elaborate further, CFD doesn't prevent sites from knowing what extensions I have, CPU I'm using, RAM, GPU, speakers, etc. Basically all the characteristics a browser leaks without anti-fingerprinting. Furthermore, this extension is abandoned and it simply doesn't work. Full stop. Sadly, the only working extension has now been infected with malware and adware. It took Google more than 3 months to finally remove it after an overwhelming number of flags/complaints. If you want anti-fingerprinting, considering using another browser like Brave or modified Firefox.

Cloudflare перестала давать доступ к сайтам из-за этого дополнения, браузер не проходит проверку безопасности. Вероятно отпечаток запрашивается несколько раз и каждый раз приходит разный ответ, пожалуйста, решите данную проблему, иначе для доступа к очень многим сайтам приходится выключать дополнение.
