Using Machine Learning to Guess PINs from Video
Full article125 words · extracted from schneier.com · click to collapse
Researchers trained a machine-learning system on videos of people typing their PINs into ATMs:
By using three tries, which is typically the maximum allowed number of attempts before the card is withheld, the researchers reconstructed the correct sequence for 5-digit PINs 30% of the time, and reached 41% for 4-digit PINs.
This works even if the person is covering the pad with their hands.
