Claim:
1. A mobile terminal for accessing an information device through a short-range communication channel, the mobile terminal comprising: a short-range communication module configured to establish the short-range communication channel; a memory configured to store authorization information for changing an attribute of an information file stored in the information device from a hidden state to a visible state or from an unaccessible state to an accessible state according to a distance between the information device and the mobile terminal, wherein the distance is a relative distance determined with reference to a location of the information device, wherein, when the information file is in the hidden state, an item indicating that the information file is stored in the information device is not visible on a display of the information device, wherein, when the information file is in the visible state, the item is visible on the display of the information device, and wherein, when the information file is in the unaccessible state, both the mobile terminal and the information device are restricted from access to the information file; and a controller for controlling the short-range communication module to transmit the authorization information when the mobile terminal is located within an effective reception distance of the short-range communication module with reference to a location of the information device, wherein, when a physical distance for authorization of the mobile terminal is designated by a user to be shorter than an effective reception distance of the short-range communication channel, the changing of the attribute of the information file is restricted even though the transmitted authorization information is valid, if the information device receives the authorization information from the mobile terminal located at a distance between the designated physical distance and the effective reception distance of the short-range communication channel.
