20090077642 | COOPERATION METHOD AND SYSTEM BETWEEN SEND MECHANISM AND IPSEC PROTOCOL IN IPV6 ENVIRONMENT - The present invention relates to a method of embodying a cooperation system between SEND and IPSec in an IPv6 environment. The cooperation system between SEND and IPSec in accordance with the present invention includes: receiving an authentication completion report message including a first IP address of a host whose authentication is completed by the SEND; generating new authentication information corresponding to the host and storing the new authentication information in a temporary storage area, if authentication information for the host is not present in the temporary storage area, wherein the authentication information includes the first IP address; and if an authentication check request message including a second IP address is received from the IPSec, checking whether the second IP address is present in the temporary storage area, and sending the result of checking to the IPSec. The present invention allows the authentication information shared between SEND and IPSec in a mobile environment, where the network is frequently accessed, enabling IPSec secure communication at a lower cost. | 03-19-2009 |
20090113538 | Method and system for controlling access for mobile agents in home network environments - Disclosed is a method and system for controlling access for a mobile agent in a home network environment. The method includes the steps of: issuing a role ticket to the mobile agent; verifying access authority to service requested by the mobile agent through the role ticket; and granting the mobile agent access authority to the service. Accordingly, a table for managing access authority of a user is distributed to devices, so that it is possible to provide the mobile agent access control method and system capable of minimizing network traffic in the home network environment. | 04-30-2009 |

20100100941 | CONTEXT-AWARE ROLE-BASED ACCESS CONTROL SYSTEM AND CONTROL METHOD THEREOF - A context-aware role-based access control system and a control method thereof. The context-aware role-based access control system includes: a context-aware user assignment manager (CAUAM) for performing a role assignment function, a role delegation function, or a role revocation function for a user according to a context of the user, based on a preset context request condition; a context-aware permission assignment manager (CAPAM) for performing a permission modification, a permission restoration, and a personalized permission modification for a permission, which the role has, according to changes in the context of the user; an information repository for storing a user profile and context information; and an access control manager (ACM) for controlling the context-aware user assignment manager, the context-aware permission assignment manager, and the information repository, and processing an access control request. Accordingly, more efficient access control can be achieved in ubiquitous environments where the context of the user dynamically changes. | 04-22-2010 |
20110037955 | LASER PROJECTION DISPLAY AND IMAGE DISTORTION CORRECTION METHOD FOR THE SAME - A laser projection display and a method of compensating for image distortion of the same stereoscopic liquid crystal display device having a touch panel and a method for manufacturing the same are disclosed. Herein, the method includes displaying a picture including a red image, a green image, and a blue image, selecting one of the red image, the green image, and the blue image so as to perform pixel alignment of the picture, calculating pixel coordinate values x+dx and y+dy corresponding to the selected image (herein, x represents the x coordinate value prior to alignment, y represents the y coordinate value prior to alignment, dx represents a varied x coordinate value after alignment, and dy represents a varied y coordinate value after alignment), calculating distortion compensation coordinate values X′ and Y′ corresponding to the pixel coordinate values x+dx and y+dy, and mapping the distortion compensation values X′ and Y′, thereby compensating for an image distortion occurring in the selected image. | 02-17-2011 |
20120141028 | Method and apparatus for automatic brightness adjustment of image signal processor - An automatic brightness adjusting method and apparatus for image signal processor (ISP) is provided. The image processing apparatus may include a histogram generating unit, a cumulative distribution function calculator, and a histogram equalization (HE) unit. The histogram generating unit may generate a histogram of brightness values of pixels in an input image. The cumulative distribution function calculator may generate a cumulative distribution function and an inverse cumulative distribution function, based on the generated histogram. The HE unit may generate a conversion function based on the cumulative distribution function and the inverse cumulative distribution function, and may apply HE to the input image based on the conversion function so as to generate an output image. | 06-07-2012 |
20120254390 | APPARATUS AND METHOD FOR TRANSMITTING PUSH NOTIFICATION MESSAGE - Provided is an apparatus and method for transmitting a push notification message. To this end, connection is performed with a mobile terminal, and if a push notification message is received from a push notification service providing server, the received push notification message is transmitted to the mobile terminal, and when disconnected from the mobile terminal, a push notification message received after the disconnection is stored, such that transmission of the push notification message can be guaranteed. | 10-04-2012 |
20120258747 | SERVER CLUSTER AND METHOD FOR PUSH NOTIFICATION SERVICE - A server cluster and method for providing a push notification service are provided. The method includes searching for, by a management server cluster, a first push server corresponding to predetermined search criteria from among a plurality of push servers upon receiving a request to connect with a push server from a mobile terminal; providing, by the management server cluster, connection information regarding the found first push server to the mobile terminal; and delivering, by the first push server, upon generation of a notification event after connecting with the mobile terminal, event information corresponding to the push notification event to the connected mobile terminal. | 10-11-2012 |
20140164990 | DISPLAY DEVICE AND METHOD OF CONTROLLING THE SAME - A method for controlling a display device that includes a touch screen is provided. The method includes establishing a plurality of window display spaces in the touch screen, wherein each of the plurality of window display spaces displays a window for running an application, displaying a launcher application in one of the plurality of window display spaces, the launcher application presenting at least one icon to run at least one application, receiving in the launcher application a new application run command to run a new application, and displaying a new window for running the new application in one of the other window display spaces than the window display space where the launcher application is displayed, in response to the new application run command. | 06-12-2014 |
20140164991 | DISPLAY DEVICE AND METHOD OF CONTROLLING THE SAME - A display device with a touch screen, which executes at least one application and a method for controlling the display device are provided.
