Typically as much of the processing for these as possible is pushed onto the underlying hardware, resulting in consistent results for a given device independently of the OS / software. There is a surprising amount of variation here. However there's not sufficient variation for it to be used in isolation from other methods.

Browser Fingerprinting - digging further into the client
I previously wrote about some techniques for Browser Fingerprinting (or "Device Identification" as it's known in some circles). Today I came across an interesting technique already in widespread use which detects variations between devices by looking at how content is rendered by WebGL / HTML5 Canvas.
