  • Patent number: 10365939
    Abstract: A method and apparatus for providing an operating system based on a lightweight hypervisor. An electronic device includes a hypervisor, an operating system monitor, and a virtualized operating system. The hypervisor enables the virtualized operating system and a physical machine to share the resources of the physical machine. If the virtualized operating system accesses the resource, the operating system monitor determines whether to allow the access to the resource. Also, the operating system monitor verifies the integrity of the virtualized operating system and determines whether a threat to the virtualized operating system exists.

  • Patent number: 8667294
    Abstract: An apparatus and method for preventing falsification of a client screen is provided, in which a web server dynamically generates URIs and provides them to clients, thus preventing the falsification of client screens due to a web injection attack or a memory hacking attack. The apparatus includes a random web generation unit for converting an identical web page into random URIs that are randomly generated, at a request of a plurality of clients, generating different random web sources, and providing the different random web sources to the respective clients. A web falsification determination unit compares display web source eigenvalues respectively generated by the clients with respect to any one of the random web sources with a generative web source eigenvalue for the one of the random web sources, thus determining whether screens corresponding to the random web sources displayed on the respective clients have been falsified.
