Abstract: A method of performing user authentication in an image forming apparatus, the method including detecting whether an interruption or a failure has occurred during authentication using an external authentication server; providing a user interface (UI) screen image for selecting to retry the authentication using the external authentication server or to enter a temporary authentication mode that does not use the external authentication server; when it is selected to enter the temporary authentication mode, entering an administrator authentication mode or an internal authentication mode based on pre-set temporary authentication options; and receiving information necessary for authentication and performing authentication based on a current authentication mode.

Abstract: A system and method for providing location-based personalized information by using user location history information, whereby battery consumption of a computing device is reduced. The computing device includes: a location finder configured to obtain user location information of a user of the computing device; a display configured to display information indicating a route of the user of the computing device; and a controller configured to track a location of the user by controlling the location finder as the controller senses a change in the location of the user based on the obtained user location information, obtain information corresponding to an initial route of the user based on the tracked location of the user, detect a predicted route of the user from user location history information based on the information corresponding to the initial route of the user, and display on the display unit the predicted route.
