Pixel Perfect: Fingerprinting Canvas in HTML5

Hovav Shacham: Pixel Perfect

Keaton Mowery and Hovav Shacham · hovav.net

Rendering text and WebGL scenes into an HTML5 canvas element and reading back the pixels yields a browser fingerprint, because font rasterisation and GPU output vary with the operating system, drivers and hardware beneath the browser. The authors report the resulting signal is consistent, high-entropy, orthogonal to existing fingerprints, and obtainable without the user noticing.
