浏览器指纹

Browser fingerprinting collects dozens of data points about your browser and device to create a unique identifier. Unlike cookies, you can't clear or block a fingerprint — it's derived from your hardware and software configuration.

This test checks the most common fingerprinting vectors:

• Canvas fingerprint — how your GPU renders a specific drawing produces a unique hash
• WebGL renderer — your exact GPU model and driver version
• Audio fingerprint — how your audio stack processes a specific oscillator signal
• WebGPU info — next-generation GPU identification
• System info — screen size, CPU cores, memory, timezone, language, touch support

Combined, these signals create a fingerprint that is unique for over 94% of browsers according to the EFF's Panopticlick research.

Tor Browser is the most effective — it standardizes all fingerprint signals across users. But it's slow and breaks many websites.

Firefox with resistFingerprinting — set privacy.resistFingerprinting = true in about:config. This spoofs many signals but may break some sites.

Brave Browser randomizes fingerprint signals by default while maintaining usability.

Anti-detect browsers (like AdsPower, GoLogin, Multilogin) create fully isolated browser profiles with different fingerprints — used by marketers managing multiple accounts.

Note: VPNs don't help with fingerprinting. A VPN hides your IP but doesn't change your browser fingerprint. Check your DNS leak status and WebRTC leak status separately.
