摘要： A CPU of a navigation apparatus stores public keys to which priorities are set and which are published by an information distribution center in a public key storage section. The CPU of the navigation apparatus extracts an electronic signature of distribution data which is distributed from the information distribution center and verifies the electronic signature by using only ‘valid’ public keys among the public keys in order of the priorities. The CPU of the navigation apparatus determines that the distribution data is valid information which is distributed from the information distribution center when the electronic signature passes verification.

摘要： When the navigation apparatus 5 performs a difference update on navigation map data 39 based on difference update data 17 distributed from a map distribution center 2, the difference update data 17 used in the difference update is stored into a navigation HDD 32, when the navigation apparatus 5 performs a total update on the navigation map data 39 thereafter, the navigation apparatus 5 performs a difference update again (S17) by using any piece of the difference update data stored in the navigation HDD 32 of which the version is newer than that of total update data. After performing the update, the navigation apparatus 5 deletes the pieces of difference update data 17 from the navigation HDD 32 that have been stored up to that point in time (S18).

摘要： Map information distribution systems and methods store map information and version information for each road category of the map information stored in a navigation device, the version information correlated with identification information identifying the navigation device. The systems and methods receive the identification information from the navigation device and obtain, based on the received identification information, the version information for each road category of the map information stored in the navigation device corresponding to the stored identification information. The systems and methods extract, based on the obtained version information for each road category, differential data for each road category with stored map information of a latest version, and transmit the extracted differential data for each road category to the navigation device corresponding to the received identification information.
