INFORMATION PROCESSING DEVICE HAVING SECURITY FUNCTION

摘要

An access information storage unit (106) contains access information defining a valid area for judging access enabled/disabled state for each of a part or whole of the data stored in a data storage unit (107). A position information acquisition unit (101) acquires position information on the current position from a position information providing terminal (300). An access judgment processing unit (102) is used when particular data having access information is accessed, for judging whether the current position obtained by the position information acquisition unit (101) is inside or outside the valid area defined in the particular data. When the access judgment processing unit (102) decides that the current position is inside the valid area, a data management unit (105) allows access to the particular data stored in the data storage unit (107). If the current position is judged to be outside the valid area, the data management unit (105) rejects access to the particular data.
