What is a canvas fingerprint?

The browser draws text to a hidden canvas and the result is hashed. Tiny rendering differences between GPUs, drivers, and OSes make the hash fairly unique.

Does this tool track me?

No. The page reads browser properties in JavaScript for display only. Nothing is sent to the server.

Which properties contribute most to fingerprint uniqueness?

Research from the Panopticlick / Cover Your Tracks projects shows fonts, screen resolution, canvas, WebGL, and timezone dominate. Languages and user-agent add smaller amounts.
