Imagine gathering screen size, installed fonts, graphics card, processor model, extensions, plugins, operating system, ... and so on. Perhaps you could gather enough system properties to actually identify someone uniquely. It’s like a fingerprint.
- dehrmann 6y agoSome of these are more interesting than others. OS is exposed through the user agent. I'm not sure if you can actually capture processor model an graphics card, and plugins were more interesting when people installed plugins like Flash and Java. WebGL fingerprinting usually works by rendering something off-screen that exposes GPU differences, then captures the rendered image as the fingerprint.
