Abstract: An electronic device is provided. The electronic device includes a memory to store an application, a communication interface to communicate with an external device, and a processor operatively connected with the memory and the communication interface. The processor determines whether the application is authenticated if receiving an installation request or an execution request of the application, generates a policy file associated with a domain of the application if the application is authenticated, and assigns the application to a specified domain, which is accessible to a secure area of the memory, based on the generated policy file.

Abstract: An electronic device includes a memory configured to store an application, a communication interface, and a processor. The processor is configured to receive a request to install or execute the application, verify whether the application is authenticated compare at least part of an icon for executing the application with a security indication associated with security of the application. The electronic device provides a result of comparing the at least part of the icon with the security indication based on whether the application is authenticated.

Abstract: A electronic device and a control method of the electronic device are provided. A control method includes providing a first environment in which at least one application can operate and a second environment having an operation environment at least partially different from the first environment; determining whether a first application among the at least one application is to be executed in the second environment, when an execution command of the first application is acquired; and executing the first application in the second environment, when it is determined that the first application is to be executed in the second environment.

Abstract: An electronic device and method of controlling an electronic device are provided. The electronic device includes a communication module; a processor; and a memory that stores instructions to instruct the processor to install a first application operating only in a first environment, install a second application selectively operating in at least one of the first environment and a second environment, grant access to the first application to first data, the first data being generated while the second application operates in the first environment, deny access to the first application to second data, the second data being generated while the second application operates in the second environment, grant access to the second application to third data, the third data being generated while the first application operates in the first environment, and allocate the second application to at least the second environment without a user's input when the second application is installed.

Abstract: An apparatus and method enabling a user to easily confirm a moving image. An apparatus for displaying thumbnails displays moving image clips in the form of thumbnails, and automatically plays a moving image corresponding to the thumbnail, on which an indicator is positioned, in accordance with a shift of the indicator. Also, if a key for adjusting the number of thumbnails displayed on a screen is input, the number of thumbnails displayed and the arrangement of the thumbnails are adjusted in accordance with the input of the adjustment key. In this case, a playback of the moving image corresponding to the thumbnail on which the indicator is positioned is maintained without interruption, and only the arrangement of the remaining thumbnail is changed.

Abstract: A method for displaying images in an image-processing device is provided. The image display method includes, if there is a multi-image display request for previously stored multiple images, determining a preset number of simultaneously-displayed images; decoding each of as many images as the number of simultaneously-displayed images among the multiple images, and adjusting a size of the decoded images according to a predetermined display image size; and simultaneously displaying the decoded images on one frame according to an image arrangement pattern which is previously set as information indicating an arrangement rule for multiple images displayed on one frame.

Abstract: A mobile terminal for providing multiple views and a multiple view display method are disclosed. The mobile terminal controls a display region so as to display at least one view for a currently executed applet, and changes display parameters included in a corresponding view according to a size of the controlled display region. Further, when more than one view is displayed, a focus may be set on any one of the displayed views according to a user's selection. When a user's key input occurs, the key input can be recognized as an input of a view having a currently set focus. Accordingly, because the user may easily identify a destination directory, a source directory, and files through a plurality of views according to an execution order, the user can more easily manage files stored in the mobile terminal.
