  • Patent number: 10032029
    Abstract: Provided is a technique to enhance security of a computer in a multi-OS operating environment. A memory image of a primary OS is in an active state, and a memory image of a secondary OS is in a non-active state. When switching is performed from the primary OS to the secondary OS, a runtime image is created, and a digest P is calculated and encrypted (C). When switching is performed from the secondary OS to the primary OS, a digest of the stopped runtime image is calculated. Only when comparison between the decrypted digest P and the calculated digest shows agreement, is switching of the primary OS allowed.

  • Patent number: 9910677
    Abstract: Provided is a manner of switching between the operating environment of a primary OS and the operating environment of a secondary OS. In certain embodiments, a HDD keeps a runtime image of the secondary OS generated in a system memory. A DMA space for allowing the secondary OS to operate is formed in a physical address space where a memory image of the primary OS is active. The runtime image of the secondary OS is transferred to the DMA space. The operation of the memory image of the primary OS is stopped and the runtime image of the secondary OS is executed in the DMA space. Before activating the memory image of the primary OS, the runtime image of the secondary OS is saved to the HDD again.

  • Patent number: 9766664
    Abstract: The invention provides a method for a portable electronic device such as a computer to be capable of safely coping with the occurrence of a surprise removal from an external hard disk drive (HDD) connected by wireless. An HDD is connected to a portable computer by wireless via a wireless extension device. First, a wireless communication path between the HDD and the portable computer is configured. Subsequently, a file is read and edited by accessing the HDD from the portable computer. Next, removal information indicating that the portable computer is away from the HDD is produced. The removal information can be produced by detecting an acceleration generated in the portable computer, or by directly detecting the distance by the strength of the wireless signal. Data under editing is saved before occurrence of surprise removal by ejecting the HDD in response to the production of the removal information.

  • Patent number: 9753739
    Abstract: The present invention provides a method of easily managing two or more OSs. A host OS, a guest OS, and a virtualization module are loaded into a primary physical address area of a main memory. The guest OS is executed in a virtual environment in a primary physical address area. A memory image of the guest OS loaded in the primary physical address area is copied to a secondary physical address area. The right of access to a processor is transferred to the guest OS copied in the secondary physical address area to execute the guest OS in a physical environment.

  • Patent number: 9483278
    Abstract: The present invention protects a memory image of an OS in a sleep state. A CPU executes a first OS or a second OS while switching there between. The first OS is loaded into a main memory, and the second OS is loaded into an auxiliary memory. The auxiliary memory may be connected to a chipset through a PCIe interface. The main memory and the auxiliary memory are configured such that, when one is in an active state where the right of access to the CPU is obtained, the other makes a transition to the sleep state where there is no right of access to the CPU while maintaining the memory image. In order to prevent one OS in the active state from accessing the main memory or the auxiliary memory in which the memory image of the other OS in the sleep state is stored, the BIOS may set a corresponding controller to disabled during a POST.
