1. an assurance is to the security system of the access security of operation system of computer;

  • This computing machine has host cpu (CPU), is used for loading procedure with the computer memory parts of operating this computing machine and the memory device that is used for storing the data that this computing machine will use by this host CPU, and this security system comprises;

    The security partitioning that in this memory device, forms, wherein this operating system is stored in the said security partitioning;

    Set up the profile parts, arranged to be used for to define at least two data access rights profiles, the first access rights profile is authorized the write access authority to said security partitioning, and the second access rights profile is not authorized the write access authority to said security partitioning;

    AndObstructing part is used for optionally blocking the data access between host CPU and the security partitioning according to said access rights profile,Wherein said obstructing part is independent of said host CPU and can disposes discretely with said host CPU;

    With under the situation of operating subsequently regardless of host CPU;

    According to the user'"'"'s data access rights profile of carrying out said data access;

    For the user who carries out said data access applies and keeps continuously the rank to the data access authority of said security partitioningWherein arrange this security system,, operating system file is gone to and write the position that is different from security partitioning, thereby even do not upgrade the operating system file in the security partitioning, the normal running of operating system still continues with during Operational System Control.
