Abstract: The present invention provides a method and apparatus for access security in a computer unit in which a user's identification is processed and ascertained by a control IC card prior to the activation of the computer unit as compared to performing a user validation after the computer unit has been activated. In particular, if the identification data were to be altered or removed prior to the normal shut down procedure within the computer unit, then the control IC card would initiate a suspend function to the computer unit to disengage all input and output (I/O) operations. If the proper personal identification data cannot be revalidated, then the computer unit would remain deactivated, thus totally preventing any unauthorized access by one or more computer hackers.
