Websites may also use technologies comparable to Canvas or WebGL fingerprinting. These methods ask the browser to render sure graphics and then analyze subtle differences within the output.

Variations in graphics cards, drivers, operating systems, and browser configurations can produce slightly totally different results.

Hardware Information

Browsers could expose sure general information concerning the hardware inside a device.
