What is browser fingerprinting?
What is browser fingerprinting?
Browser fingerprinting collects data points about your browser and device — screen size, fonts, graphics card, timezone, language, and dozens more — to create a unique identifier for you. Unlike cookies, it cannot be deleted and works even in private/incognito mode.
Is browser fingerprinting legal?
It exists in a grey area. In the EU, collecting fingerprint data without consent may violate GDPR. In the US there are fewer restrictions. Most ad networks and tracking companies use fingerprinting alongside cookies for cross-site tracking.
How do I protect against fingerprinting?
Use Tor Browser (which standardises fingerprints), Brave browser (which randomises canvas and WebGL data), or Firefox with resistFingerprinting enabled. Privacy Badger and uBlock Origin help but cannot fully prevent fingerprinting.
What is a canvas fingerprint?
When your browser draws text and shapes on an invisible canvas element, tiny differences in GPU, fonts, and rendering produce a unique image. The hash of this image becomes part of your fingerprint — even if you change IPs or delete cookies.
Can I be identified across different sites?
Yes. If multiple websites use the same tracking network, your fingerprint can link your activity across all of them without cookies. This is called cross-site tracking.
