Map data processing method, map data processing device, storage medium, and on-board map data processing device

When a memory card (30) is inserted into a kiosk terminal (20) by a user and a command is given for a specific map data to be purchased, the kiosk terminal (20) stores the map data on the memory card (30). At this time, the kiosk terminal (20) encrypts a portion of the map data using a serial number...

Zusammenfassung:	When a memory card (30) is inserted into a kiosk terminal (20) by a user and a command is given for a specific map data to be purchased, the kiosk terminal (20) stores the map data on the memory card (30). At this time, the kiosk terminal (20) encrypts a portion of the map data using a serial number which is a code specific to the memory card (30) as the key. Then, when the memory card (30) is inserted into a navigation system (10), the navigation system (10) reads the map data stored on the memory card (30) and decrypts the encrypted portion which includes the read map data using the serial number of the memory card (30) as the key. As a result, it is possible to minimize illegal copying of the map data onto another storage medium.
