Researchers are trying to use AI to detect “social norms violations.” Feels a little sketchy right now, but this is the sort of thing that AIs will get better at. (Like all of these systems, anything but a very low false positive rate makes the detection useless in practice.) News article. Powered by WPeMatico

It’s neither hard nor expensive: Unlike password authentication, which requires a direct match between what is inputted and what’s stored in a database, fingerprint authentication determines a match using a reference threshold. As a result, a successful fingerprint brute-force attack requires only that an inputted image provides an acceptable approximation of an image in the … Read More “Brute-Forcing a Fingerprint Reader” »
