Fingerprinting
Tracking
It's like someone knowing it's you just by the way you walk and dress — even if you didn’t say your name.
Definition
A technique websites use to track users by collecting unique characteristics from their devices and browsers.
In plain English
It's like someone knowing it's you just by the way you walk and dress — even if you didn’t say your name.
Why this matters
Fingerprinting works even without cookies. It’s hard to block and very invasive.
Example
Browsers like Brave and Firefox try to randomize your fingerprint to block tracking.
