<p>A collating determination section (220) compares home position information (183) and current position information that is obtained from a GPS receiving unit (170) or from a position (122) of the preceding stop of a vehicle. Further, the collating determination section (220) calculates the difference between the current time obtained from a timing unit (113) and a time (182) at which the preceding collation succeeded, and when there is a difference greater than a predetermined level, the collating determination section (220) compares identification information inputted from an operation input unit (150) and identification information on an identifier (181) for collation. When these pieces of identification information do no agree with each other, the collating determination section (220) informs a function stop section (230) to stop the function of an information processing device. Then, the function stop section (230) stops the function of the information processing device. Thus, the information processing device is prevented from theft with user's convenience taken into account.</p> |
