Abstract: PROBLEM TO BE SOLVED: To provide a reliable method/system of safety protection of a computer, which a possessor can easily use. SOLUTION: The method contains a step for installing the operation permission zone of a computer, a step for judging whether the possessor of the commuter is permitted to possess it when the computer and the possessor leave the operation permission zone and they pass through a portal and a step for permitting continuous access to the computer without the request of a password if the possessor is permitted. The method and a system are transparent for the possessor and to hide the computer from the portal does not bring any advantage. The method and the system can easily be applied to company environment and are especially suitable for the safety protection of the mobile computer system.

Abstract: The present invention provides a method and system for securing a computer and a computer for use in such method and system. The method includes providing a zone 302 of authorized operation for the computer 306; determining if a possessor of the computer is authorized to have possession when the computer and the possessor leaves the zone of authorized operation and pass through a portal 316; and allowing continued access to the computer without requiring a password if the possessor is authorized. The method and system are transparent to the possessor and provide no advantage in hiding the computer from the portal. This method and system may be easily applied in a corporate environment and are particularly apt for securing mobile computer systems.
