What is Canvas Blocker - Fingerprint Protect?
"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.
This browser extension safeguards user privacy by preventing malicious scripts from using the HTML canvas element for user fingerprinting. It introduces slight changes to the data generated by the canvas element when specific methods are invoked, rendering it unusable for fingerprinting. In comparison to similar extensions, this one is lighter and employs a more efficient method to obstruct fingerprinting across all frame elements (top and subframes). The extension operates in three modes:
- Random noise
