Analyzing browser fingerprint...
What is Browser Fingerprinting?
Browser fingerprinting collects dozens of attributes about your browser and device to create a unique identifier. This includes your screen resolution, installed fonts, browser plugins, timezone, and even how your graphics card renders images.
Unlike cookies, fingerprints are nearly impossible to delete because they're based on your device's inherent characteristics.
Fingerprinting Techniques
Canvas Fingerprinting
Uses HTML5 Canvas to draw graphics that render differently on each device.
WebGL Fingerprinting
Identifies your graphics card and driver through WebGL rendering.
Audio Fingerprinting
Analyzes how your system processes audio signals.
Font Detection
Detects which fonts are installed on your system.
How to Reduce Your Fingerprint
- 1.Use the Tor Browser, which is designed to make all users look identical
- 2.Use Brave Browser with its built-in fingerprint randomization
- 3.Install privacy extensions like CanvasBlocker or Privacy Badger
- 4.Use Firefox with privacy.resistFingerprinting enabled in about:config
Frequently Asked Questions
What is browser fingerprinting?
Browser fingerprinting is a technique websites use to identify and track users by collecting information about their browser and device. Unlike cookies, fingerprints cannot be easily deleted and work even in private/incognito mode.
How does canvas fingerprinting work?
Canvas fingerprinting draws invisible graphics using your browser and extracts the resulting image data. Due to differences in hardware, drivers, and fonts, each device renders these graphics slightly differently, creating a unique identifier.
Can I prevent browser fingerprinting?
You can reduce fingerprinting by using privacy-focused browsers like Tor or Brave, installing anti-fingerprinting extensions, disabling JavaScript (though this breaks most sites), or using browser settings that block canvas/WebGL access.
Why is a high uniqueness score bad?
A high uniqueness score means your browser configuration is rare, making it easier for websites to identify and track you across the internet without using cookies. A more common fingerprint provides better anonymity.
