A device may be authorized via a method, which includes: displaying several numbered folder objects while the device is in an unauthorized state, each of which is displayed with a corresponding serial number and represents a folder containing several files stored in the device; executing a predefined operation toward one of the folder objects; detecting the serial numbers corresponding to the operated folder object; comparing the detected serial numbers and a predetermined password; and maintaining the device in the unauthorized state, if the detected serial numbers do not correspond to the password.
