ABSTRACT:
An information handling system security system validates authorization to selected information by establishing physical access of a user to the information handling system through activation by the user of a power switch of the information handling system. Upon detection of an attempt to access the limited access information, a trusted platform module disables power functionality of the power switch and enables a physical access validation mode that validates physical access of a user to the information handling system before allowing access to the limited access information. Failure to confirm physical access by activation of the power switch precludes access to the information. Validation of physical access by activation of the power switch allows access to the information and returns normal power functionality to the power switch.
