Abstract: A terminal may backup data in a cloud server. The cloud server may generate a virtual device to perform substantially the same operations as the terminal, and may install an application in the virtual device if the application is determined to be unreliable by the terminal. The cloud server performs a reliability evaluation of the unreliable application and transmits the results of the reliability evaluation to the terminal. In addition, the terminal may store backup data in the cloud server. If the terminal malfunctions, the terminal may be restored by receiving the stored backup data from the cloud server. The terminal may remotely execute an application installed in the virtual device.

Abstract: A terminal device may backup data in a cloud server. The cloud server may generate a virtual apparatus to perform substantially the same operations as the terminal device, and may install an application in the virtual apparatus prior to the application being installed in the terminal device, thereby performing a virus check before the application is installed in the terminal device. In addition, the terminal device may store backup data in the cloud server. If the terminal device malfunctions, the terminal device may be restored by receiving the stored backup data from the cloud server.

Abstract: A method for providing AR information, in which the method includes receiving virtual object setting information by a first terminal, in which the virtual object setting information including virtual object selection information and movement setting information; and transmitting a request to a server for uploading a virtual object onto a real-world image of a target location based on the virtual object setting information. An apparatus to provide AR information, in which the apparatus includes a communication unit to process signals received from a server and to transmit signals to the server; a display unit to display a real-world image of a target location; a manipulation unit to receive a user input signal; and a control unit to receive virtual object setting information and to request the server to upload a virtual object onto the real-world image of the target location.

Abstract: A portable terminal to provide social network service using human body communication includes a human body communication unit to transmit or receive data through a human body, a memory unit to store at least one of social data, user data, reference data, and any additional data collected, a contact object identifying unit to identify a contact object by using the data received by the human body communication unit, and a pattern analyzing unit to analyze a pattern of contact with the contact object using the data stored in the memory unit. A method for providing social network service using human body communication includes sensing a human body contact, identifying a contact object, and analyzing a pattern of contact with the contact object using at least one of social data, user data, reference data and any additional data collected.

Abstract: An experience modification apparatus for a mobile terminal generates a modification event upon detecting execution of an application provided by the mobile terminal or upon detecting a specific order of key inputs so as to modify the applications of the mobile terminal.
