Abstract
Abstract The present invention is a method and apparatus for controlling access to at least one program on a processing system by verifying data entered through a keyboard, while isolating the entered data from the processing system. The apparatus comprises a memory and a processor coupled to the memory. A first data path is provided between the keyboard and the processing system; a second data path is provided between the keyboard and the processor; and a third data path is provided between the processing system and the processor. When activated, the processor is operable in a first mode wherein access to the processing system via the keyboard is inhibited when data entered via the keyboard does not match data stored on the card. The processor is operable in a second mode, wherein the keyboard is coupled to the processing system so that the at least one program on the processing system is accessible via the keyboard when the entered matches the data stored on the card. Various embodiments are disclosed.
