I want everyone to click on this paper and then maybe help explain it to
me! From what I understand they got a fingerprint reader to tell them
how hot/cold they were to an acceptable fingerprint. So they they modify
a fingerprint to get closer and closer until it matches.

DOES THAT EVER HAPPEN IN REAL LIFE? I'm so confused at what security
system gives you a "hot/cold" value so you can use this algorithm. Could
this paper be summed up to say in one sentence "Obviously if you give a
matching score from your biometric, you can use a model of that
biometric to retrieve the raw data with enough tries?"
