Abstract
A method for ensuring security of a system accessed utilizing a keypad wherein access is provided to said system via a security code entered on the keypad. A security code is entered on the keypad utilizing a first character configuration of the keypad. Following this, the location of one or more access characters on the keypad is repositioned to present a second character configuration of the keypad. The repositioning of the character configuration is completed electronically in a generally random manner. The change in configuration may take place immediately after each user interface, or after a predetermined number of user interfaces.
