Canvas Blocker - Fingerprint Protect

Prevent HTML canvas element from generating a unique identification key to protect user's privacy

Canvas Blocker - Fingerprint Protect Chrome Extension

"Canvas Blocker - Fingerprint Protect" is a Chrome extension designed to protect user privacy against malicious scripts that use the HTML canvas element for fingerprinting. It disrupts the creation of a unique identification key by introducing slight variations in the data produced by the canvas element. It operates in three modes; random noise, random noise per page, and fixed noise, while providing a range of features including blocking or disabling fingerprinting on specific hostnames, and alerts for detected canvas fingerprinting.
