Abstract:
A method of operating a storage device including a nonvolatile memory device and a storage controller that is configured to control the nonvolatile memory device, the method comprising: partitioning the nonvolatile memory device into a plurality of domains; determining a scramble function based on a seed value of seed bits that correspond to a first portion of a plurality of address bits of a logical address among a plurality of logical addresses that are provided from a host device; generating a scrambled domain value based on the scramble function and a domain value of domain bits that correspond to a second portion of the plurality of address bits of the logical address among the plurality of logical addresses; and assigning a write operation that corresponds to the logical address to a domain that corresponds to the scrambled domain value among the plurality of domains.
Abstract:
A method and an apparatus for executing applications in a highest-priority-first order in the processor divided into a secure mode area and a non-secure mode area are provided. The method includes receiving a request to be processed in the non-secure mode domain from the application, determining an access permission level configured to a resource used for processing the request, determining, when the access permission level allows for access from the secure mode domain, a priority of the application, changing the access permission level to allow for access by the non-secure mode domain according to the priority of the application, and processing the request of the application using the resource in the non-secure mode domain.
Abstract:
A method and apparatus for improving application processing speed in a digital device which improve application processing speed for a digital device running in an embedded environment where processor performance may not be sufficiently powerful by detecting an execution request for an application, identifying a group to which the requested application belongs, among preset groups with different priorities and scheduling the requested application according to the priority assigned to the identified group, and executing the requested application based on the scheduling result.
Abstract:
A user preference analysis method and device are provided for providing a user with customized content through preference analysis based on the user's content consumption activity. The user preference analysis method includes displaying content data on a screen of the device in response to a user input; recording content information about the content data displayed on the screen; analyzing a user preference based on the recorded content information; and storing a user preference analysis result for the content data.
Abstract:
A method and an electronic device are provided for operating a security function. The method includes receiving a request for activation of a security function, confirming whether a security indicator is set, and when the security indicator is set, applying the security indicator to a security function screen image, based on activation of the security function, and outputting the security function screen image to a display of the electronic device.

Abstract:
A method and apparatus for securing touch input are provided. The method includes rendering a first screen in a secure world; rendering a second screen in a non-secure world; and outputting a secured input screen by displaying the first screen as an overlay above the second screen.
Abstract:
A social data management system and a method for operating the same capable of managing social data with respect to various social networking services based on a mobile platform through a social data management system in a mobile device are provided. A system for supporting a social networking service includes a plug-in manager for managing social data of the social networking service used by a user through a plug-in library structure; and a common characteristic processor for tracking an activity of the user based on use of an SNS of the user to extract a user interest keyword, extracting another user whose interest is similar and social contents, and automatically selecting social content preferred by the user, and giving a priority to the selected social contents.
