Method of managing map information, navigation system, information terminal, and navigation device

摘要

A method of managing map information including: attaching a retrieval identifier, according to input information, to map information which is obtained by retrieval based on the input information, the retrieval identifier indicating whether the map information is personal data or public data; storing the map information as the personal data into a storage device, the map information being indicated to be the personal data by the retrieval identifier attached in the attaching, and storing the map information as the public data into the storage device, the map information being indicated to be the public data by the retrieval identifier; and executing a navigation process using at least one of the personal data and the public data which are stored in the storage device.

1. A method of managing map information by a navigation system including an information terminal that makes a route retrieval, a navigation device which executes a navigation process using a result of the route retrieval, and a storage device included in a server connected to the information terminal and the navigation device over a network, the method comprising:
attaching a retrieval identifier to the map information which is obtained by retrieval based on information inputted to make the route retrieval, the retrieval identifier indicating whether the map information is personal data or public data and being attached according to the information inputted; (i) storing the map information with the attached retrieval identifier as the personal data into the storage device when the retrieval identifier attached in the attaching indicates the personal data, and (ii) storing the map information with the attached retrieval identifier as the public data into the storage device when the retrieval identifier attached in the attaching indicates the public data; executing the navigation process by the navigation device using at least one of the personal data and the public data which is stored in the storage device; assigning the map information, which is indicated to be the personal data by the retrieval identifier, to a personal data storage which is accessible only from a specific user in the storage device, and assigning the map information, which is indicated to be the public data by the retrieval identifier, to a public data storage which is accessible from unspecified number of users in the storage device, according to the retrieval identifier; receiving user identification information which allows identification of a user, and a read request for the personal data and the public data which are stored in the storage device; and permitting the public data stored in the public data storage to be read according to the read request for the public data received in the receiving, and only when the personal data storage is present which corresponds to the user identification information received in the receiving, permitting the personal data stored in the personal data storage to be read according to the read request for the personal data, wherein in the attaching, when the information inputted is a marker on a road map or an address, the retrieval identifier indicating the personal data is attached to the map information which is obtained by the retrieval based on the information inputted, and when the information inputted is a name, the retrieval identifier indicating the public data is attached to the map information which is obtained by the retrieval based on the information inputted.
