What this means
The canvas hash is very stable on one device and almost never repeats across devices, which makes it a favourite of tracking scripts. If "noise injection" says yes, your browser (Brave or a privacy extension) perturbs every draw, so websites get a different hash each time and cannot track you reliably with it.
