Abstract
A method for entering secure data at an input device includes displaying a graphical input region having input elements, such as a number keypad, and receiving selections of the input elements via a display selection device, such as a mouse or touch screen. An attribute of the displayed graphical input region is changed so that inputs by the display selection device change for the same data input. Examples include changing the position, size and/or layout of the input elements and/or graphical input region. The graphical input elements may instead be provided with two characters so that typing one character results in input of the corresponding character, and then changing the association of the characters on the displayed input elements.
