Abstract
An information handling system (IHS) (e.g., a terminal, automated teller machine, etc.) initiates a password input session, creates a Random Transformation Algorithm (RTA) for the input session, instructs an IHS user to apply the RTA to entry of a key sequence of the password, accepts entry of the key sequence from the user via an IHS keyboard and/or keypad, and reverses transformation of the user entry of the key sequence in accordance with the RTA logically arriving at the password. The IHS may then (encrypt and) send the password to a server for authentication. The RTA may swap keyboard and/or keypad characters by position and/or value, shift keyboard and/or keypad character values up or down, geometrically move keyboard and/or keypad characters, and/or rotate keyboard and/or keypad characters about an axis. The instructions may be communicated to the user via a third party device, the keyboard, a display, or the like.
