    One of them: Canvas Fingerprinting. They draw an image in the background using vector graphic commands. Afterwards they save the image to a rasterized PNG. This data is quite unique among different devices depending on settings and hardware.

    They also use audio fingerprinting to identify visitors. This doesn’t mean they actually use your microphone or speaker. Instead they generate a sound internally and record the bitstream, which also differs from device to device.
