Abstract:
     The invention relates to a navigator encrypt system and method that the system includes hardware module used to store first data, map module storing the second data and the third data corresponding to the hardware module, and navigation module. The method includes the following steps: generating the first data and storing in the hardware module, generating the second data and third data and storing in the map module; the navigation module reading the first data, the second data and the third data from the hardware module and map module, judging whether the map module is matching to the hardware module. The navigator encryption system and method of the invention could encrypt the navigation map module and navigate hardware module to make special map data only use on special hardware device to enhance the copyright protection for map data.
