Researchers develop tool to withdraw cash from ATMs using Google Glass

Researchers have come up with a concept that would potentially allow for safe money withdrawal from ATMs via Google Glass.


Dominique Schroder, IT expert and assistant professor of cryptographic algorithms at the Saarland University in Germany, has proposed to combine Google Glass with cryptographic methods and techniques from automated image analysis to create a software system 'Ubic', which would allow you to withdraw from ATMs without leaking confidential data.


This is how the system works: The customer first identifies himself to the cash machine. It uses the public key to encrypt the one-way personal identification number (PIN) and seals it additionally with a 'digital signature'. The result shows up on the screen as a black-and-white pattern, a so-called 'QR' code. The PIN that is hidden below is only visible for the identified wearer of Google Glass, and not to anyone else. Since no one else can snoop into what you see on Glass, it's practically impossible to detect the pin.


"Google Glass decrypts it and shows it in the wearer's field of vision. Although the process occurs in public, nobody is able to spy on the PIN," Schroder said. To spy on the PIN while it is being entered would also be useless since the PIN is re-generated each time the customer uses the ATM kiosk.


The digital signature guarantees that no assailant is able to intrude between the customer and the cash machine as during 'skimming' where PINs being entered into a traditional ATM keypad are spied on. Here, only the customer is able to decrypt the encryption by the public key with the unique secret key. "As long as this is safely stored on the Google Glass, his money is also safe," said Schroder, who also does research at the Center for IT-Security, Privacy and Accountability in Germany.
