<p><P>PROBLEM TO BE SOLVED: To provide a technique capable of preventing the leakage of data recorded by a driver recorder. <P>SOLUTION: In a data display device, a security code set by a user is stored in a hard disk and is also recorded in a memory card used for recording of data by a drive recorder. When reading the data in the memory card, when the security code recorded on the memory card matches with the one stored in the hard disk, the data recorded in the memory card are read and displayed at the display. Thus, the data recorded in the memory card cannot be displayed unless the security code is recognized, thereby the leakage of the data recorded in the driver recorder is effectively prevented. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
