Lego Mindstorm robot used to improve ATM security

February 11, 2008

Ars Technica:Researchers working through Carnegie Mellon University's CyLab have devised a new kind of security system that aims to block observation attacks at ATMs. When the researchers created their prototype, which is called "Undercover" and was built with a Lego Mindstorms robot, they attempted to come up with a system that would be easy to use but would limit vulnerability to common ATM attacks. Unlike many conventional security systems, which use secret responses like passwords, the Undercover system partially obfuscates the query, making the query use both visual cues from images and tactile cues provided by a rotating and vibrating ball that the user covers with his hand.
