Canvas Fingerprinting: The Tracker That Doesn't Need Your IP

Introduction: The Invisible Drawing

If you hide your IP address with a VPN and clear your cookies, you might think you are anonymous. You aren't. Advertisers use an advanced technique called Canvas Fingerprinting. It bypasses network settings entirely and looks directly at your computer's graphics card.

How It Draws Your ID

When you visit a site, the tracker asks your browser to draw a hidden, complex 3D shape (a Canvas). Because every combination of Graphics Card, Operating System, and Web Browser draws curves slightly differently at the microscopic pixel level, the resulting drawing acts as a 100% unique fingerprint for your specific laptop.

Conclusion

While an IP hides your location, Canvas Fingerprinting reveals your exact piece of hardware. True privacy requires blocking both. Test your browser fingerprint here.
