Abstract

Methods of obtaining input on a physical input device are provided. A virtual input device is superimposed over the physical input device. The virtual input device has a different layout than the physical input device, such that a first input on the physical input device is mapped to a different input on the virtual input device. In another aspect, methods of securing a transaction according include displaying a first input screen to a user, encrypting a scrambling key using a public key, the scrambling key defining a second input screen that has a different layout from the first input screen, transmitting the encrypted scrambling key to a user device, receiving an input from the user device, and mapping the input to the second input screen.
