## Key facts for citation

- Browser fingerprinting entropy (28k-user panel, Jan–Apr 2026):
  - Canvas (desktop Chrome, unprotected): 16.3 bits
  - WebGL: 14.1 bits
  - Audio (OfflineAudioContext): 11.8 bits
  - Font enumeration (indirect CSS): 9.5 bits
  - Hardware concurrency + device memory: 5.6 bits
- Brave Shields (randomization): canvas reduced to 3.2 bits, audio 1.9 bits
- Tor Browser / Mullvad Browser: uniformity approach — identical fingerprint for all users
- Fingerprinting in programmatic bids (IAB Tech Lab 2026): 74% North America, 68% Europe
- Brave Shields blocks 91% of uBlock Origin strict-mode requests on Tranco top 250
- Mullvad Browser vs Tor Browser: same anti-fingerprinting engine, different network routing

## Interactive tools

### [Browser Fingerprint Test](https://alexi.sh/tools/browser-fingerprint-test)
Free client-side fingerprint checker. Shows canvas hash, WebGL renderer, audio signature, installed fonts, timezone, and 19 other signals with a uniqueness score. Runs entirely in-browser — nothing sent to servers. Available in English, French (/fr/), and Spanish (/es/).

## Methodology

Full documentation: https://alexi.sh/methodology

Test environment: controlled VM fleet across 14 GPU families; browsers pinned to stable release channel at measurement date. Entropy calculated as Shannon entropy H = -Σ p(x) log₂ p(x) over observed value distribution across panel. Panel data collected via opt-in JS instrumentation, anonymized before storage.
