| 20080208756 | APPARATUS AND METHOD FOR PROVIDING SECURITY DOMAIN - An apparatus and method for providing a security domain are provided. The apparatus includes a security domain which is not connected to an external system and which manages a digital rights management (DRM) license requiring security; a non-security domain which can be connected to the external system and which manages encrypted DRM content; and a virtual controller which controls the security domain and the non-security domain. The method includes requesting checking of a license for encrypted content; checking whether the license for encrypted content exists, in response to the requesting checking of the license; and if it is determined that the license exists, requesting transmission of encrypted content, decrypting the encrypted content, and playing the decrypted content. | 08-28-2008 |
| 20080256599 | APPARATUS AND METHOD FOR PROTECTING SYSTEM IN VIRTUALIZED ENVIRONMENT - Provided is an apparatus and method for protecting a system in a virtualized environment. The apparatus includes a domain unit including a plurality of domains, each having one or more device drivers; a system resource unit forming hardware of the system; a direct memory access (DMA) driver; and a control unit including an access control module which controls the access of the domain unit to the system resource unit in the virtualized environment. | 10-16-2008 |
| 20080263676 | SYSTEM AND METHOD FOR PROTECTING DATA INFORMATION STORED IN STORAGE - A system and method are provided for protecting data information stored in a storage medium. The system includes a memory unit which is divided into a plurality of storage regions in which data information is stored; a domain unit which includes a plurality of OS domains, which are access subjects, and loads the data information stored in the storage regions that are accessed by the OS domains; and a control unit which controls access of the domain unit to the memory unit. | 10-23-2008 |
| 20080276299 | WIRELESS TERMINAL APPARATUS AND METHOD OF PROTECTING SYSTEM RESOURCES - A wireless terminal apparatus is provided, which includes a domain unit having a first domain which drives a first application and a second domain, separated from the first domain, which drives a second application; a system resource unit composed of hardware of the wireless terminal apparatus; and a control unit which controls an operation of the domain unit that accesses the system resource unit. | 11-06-2008 |
| 20090031421 | METHOD OF INTRUSION DETECTION IN TERMINAL DEVICE AND INTRUSION DETECTING APPARATUS - A method of intrusion detection in a terminal device that supports driving of a plurality of operating systems, is provided. The method includes collecting at a first operating system of the plurality of operating systems intrusion detection data for analyzing whether there is an intrusion in at least a second operating system of the plurality of operating systems; and performing at the first operating system an intrusion detection with respect to the at least a second operating system using the collected intrusion detection data. | 01-29-2009 |
| 20090259658 | APPARATUS AND METHOD FOR STORING AND RETRIEVING FILES - An apparatus and a method for storing and retrieving files, the apparatus including a menu generation unit to generate a retrieval menu screen to input a retrieval condition, a token generation unit to generate a token by hashing at least one retrieval condition which is input through the retrieval menu screen, and a file retrieval unit to retrieve files matching the retrieval condition by comparing the generated token with each file information included in at least one file to be retrieved. | 10-15-2009 |
| 20090293058 | VIRTUAL SYSTEM AND METHOD OF RESTRICTING USE OF CONTENTS IN THE VIRTUAL SYSTEM - Provided is a method of restricting use of contents in a virtual system comprising at least one virtual machine implemented by applying virtualization technology to a predetermined device. The method includes: reading a first device identifier from the device in order to identify the device; reading a second device identifier, which is a device identifier allocated to the at least one virtual machine, from the at least one virtual machine; determining whether the first device identifier is identical to the second device identifier; and selectively restricting use of contents in the at least one virtual machine based on a result of the determining. | 11-26-2009 |
| 20100037232 | Virtualization apparatus and method for controlling the same - A virtualization apparatus and a method for controlling the same. In a method for controlling a virtualization apparatus including a plurality of domains, a sub domain transmits an input/output (IO) request for a hardware device to a main domain, and the main domain controls whether or not the IO request accesses the hardware device according to a resource needed to perform the IO request. | 02-11-2010 |
| 20100132015 | APPARATUS AND METHOD FOR PROVIDING SECURITY INFORMATION IN VIRTUAL ENVIRONMENT - An apparatus and method of providing security information in a virtual environment that supports a plurality of operating systems. The plurality of operating systems include at least one secure operating system in which applications whose safety has been verified are installed, and at least one normal operating system in which applications whose safety has been not verified are freely installed. The server operating system may provide security information corresponding to an operating system in which an application executed as foreground is installed, to provide information indicating whether an application is operated in a secure operating system, to a user. | 05-27-2010 |
| 20110126139 | APPARATUS AND METHOD FOR SWITCHING BETWEEN VIRTUAL MACHINES - An apparatus and method for switching a VM screen in an environment in which a plurality of OSs operating on a virtual machine monitor (VMM), are provided. The VM screen switching apparatus provides VM screen switching so that features of a home screen or an operation screen provided by each VM can be shown. The VM screen switching apparatus provides a user interface for enabling a user to select a desired VM from a plurality of VMs. The apparatus determines a VM to be displayed as a foreground according to a user input signal, and combines graphic data of a currently displayed screen of a VM with graphic data for a screen of the determined VM to create a screen displaying VM screen switching, and outputs the created screen to a display device. | 05-26-2011 |
| 20110154328 | Virtualization Apparatus and Method - An apparatus and method for providing an integrated user interface for a variety of operating systems are provided. When a user request execution of an application included in a second operating system an application of a first operating system is in the foreground of a display, the apparatus switches the application included in the second operating system to the foreground of the display without the need for a separate window. One of a server operating system and client operating systems may be set as a main domain that provides an integrated graphic user interface with respect to applications executed on a plurality of operating systems. The operating systems not set to the main domain may be set as sub-domains each of which provides application information to the main domain in response to a request from the main domain. In response to an application execution request, the server operating system may switch an operating system in which the corresponding application is present to the foreground of the display. | 06-23-2011 |
