alt Hacker NewsYea that is a strong fingerprint. Especially if any of the other things were correct or someone has a way to model your behaviors. How long you scroll vs how often you type etc. and somehow that's still not enough for big tech and they need biometrics, photo IDs, etc.
Yeah, the bottom counter on the page is meant to make exactly that point. Mouse movements, scroll velocity, tab switches, reading pauses are all features in modern fraud / "trust" scoring systems alongside the static fingerprint. Biometrics is the next layer, and it's already happening on the back of "passive" liveness detection most people never see.
