/lab/fingerprintLive demo

Hall ofmirrors.

A device fingerprinting lab: scan the QR code with your phone, enter the room, and watch the board recognize you purely from the signals your browser exposes - no cookies, no login. Then try to escape: open incognito or clear your cookies and come back. The point of the demo is that it will recognize you anyway.

Your fingerprint in this browserReading signalsComputed here, on your device. Nothing leaves until you create the room. Open it in incognito: it will be the same.

What we're going to collect

  • 2D canvas and GPU rendering (WebGL vendor/renderer)
  • Your AudioContext fingerprint
  • Installed fonts, screen resolution and pixel density
  • Time zone, language, reported CPU cores
  • Mouse movement patterns and typing cadence (only while you are in the room)

Each dot is one signal on that line: filled means it was already read in this browser.

None of this is stored permanently: each room lives for a maximum of 2 hours and purges itself. There is no tracking outside this demo and it is never combined with any other data on the site.

Estimated uniqueness

An educational estimate using weights from published studies (EFF Panopticlick / AmIUnique), not a population measurement.
