Abstract: A server is provided comprising a processor configured to: receive an indication of a location of a first device that is subscribed to a disaster notification service; in response to receiving a disaster alert, detect that the first device is located in an area associated with the disaster based on the indication of the location of the first device; identify a second device that has registered the first device as a friend; and transmit a first indication of the disaster to the first device and a second indication of the disaster to the second device.

Abstract: Disclosed is an electronic device including a memory storing collected location information of the electronic device, and a processor configured to convert the collected location information into code information which represents a specific area of the earth. The electronic device transmits the code information to a disaster information providing device for which location information management is required in association with the provision of disaster information. Further disclosed is a disaster information providing system including the providing device and a plurality of mobile electronic devices. Disaster-related information is provided to those devices determined to be located within a damage zone, as determined by location information obtained by the respective devices and provided to the disaster information providing device.

Abstract: A method for display, at a first electronic device, identification information about a second electronic device is provided. The method includes receiving a call or a message from the second electronic device, requesting identification information about the second electronic device to a server, receiving the requested identification information from the server, and displaying the received identification information on a screen. The identification information comprises relation information between the first electronic device and the second electronic device.

Abstract: A successive video recording method and portable device for recording video in continuation at the end of a previously-stored video file to create a merged video file without special editing applications or special skills. A video file stored in a storage unit of the portable device is selected, and a camera unit is activated a camera unit when the video file is selected. A new video file is generated by merging video data acquired by the camera unit in real time with the selected video file based on a successive recording information. The present invention enables recording video in formats including but in no way limited to Moving Picture Experts Group 1 (MPEG-4) in continuation at the end of a previously-stored video file, allowing the user to pause and resume video recording at any time and merge the video files into a single file using a successive recording mode.
