What This Means
🔍 Uniqueness: Your browser fingerprint is likely unique among thousands or millions of users. Websites can track you even without cookies.
📊 Data Exposure: You're broadcasting data points that create a unique identifier.
🛡️ Protection Tips:
- Use privacy-focused browsers (Brave, Firefox with privacy extensions)
- Enable tracking protection and fingerprint blocking
- Use VPN to mask your IP address and location
- Disable unnecessary browser plugins
- Clear cookies and cache regularly
How to Check Your Browser Fingerprint
- Run the scan - Tool automatically collects browser data points
- View your fingerprint - See all exposed data (fonts, plugins, canvas hash)
- Check uniqueness score - How identifiable you are (lower is better)
- Get privacy tips - Suggestions to reduce fingerprinting surface
How Browser Fingerprinting Works
Your browser reveals 30+ data points: User agent, screen size, timezone, installed fonts (via document.fonts), canvas rendering (unique to GPU/drivers), WebGL vendor/renderer, audio context properties, and more. Combined, these create a unique 'fingerprint' - even with cookies disabled.
Canvas fingerprinting explained: Websites draw hidden text/shapes on a <canvas> element, then read pixel data with toDataURL(). Tiny differences in GPU rendering, font rendering, and anti-aliasing create unique hashes. This tool demonstrates the technique by showing your canvas hash.
Pro tip: To reduce fingerprinting: use Tor Browser (randomizes fingerprint), enable Firefox's resistFingerprinting flag, disable JavaScript on untrusted sites, or use browser extensions like Canvas Blocker. But beware: being too unique (e.g., only Tor user on a site) can make you stand out. The sweet spot is 'blending in' with a common configuration.
