SYSTEM AND METHOD OF SECURE DATA ENTRY

摘要

A computational device having a user interface is disclosed, the user interface enables a user to securely enter data into the computational device. In particular, the user interface may include a user input portion and a user output portion. The user input portion may be partitioned into a number of input zones, each having a data value associated therewith that when engaged by a user causes the data value associated with the engaged input zone to be provided as input to the computational device.

主权项

1. A method of securely receiving user input at a computational device, the method comprising:
detecting user engagement of a user input at a first input zone of the user input; determining a first data value corresponding to the first input zone; displaying the first data value to the user via a user output; detecting user engagement of the user input at a second input zone of the user input; determining a second data value corresponding to the second input zone; displaying the second data value to the user via the user output; determining that the user has disengaged the user input at the second input zone; and in response to determining that the user has disengaged the user input at the second input zone, conditioning the second data value as input data for the computational device.
