The current invention presents a method and an apparatus to verify the identity of a user requesting access to a secure system. The method differentiates itself from the known systems by preventing unauthorized users form being able to gain access to the system either by observing what the authorized user inputs to the system or by stealing a piece of hardware form the authorized user. This is achieved by the system comparing the result of the user applying a memorized algorithm to a random number presented by the system, and the result of the system applying an algorithm to the same random number. |
