Abstract

Provided is a navigation server and a navigation client capable of protecting information specific to each user that is transmitted from the navigation client to the navigation server securely without degrading user-friendliness. A navigation server 100 is configured to, prohibit the navigation client 200 from accessing the navigation server 100 when a navigation client 200 meets a second condition that is determined from past communication contents with the navigation client 200. The navigation server 100 is configured to, make the navigation client 200 output a message urging to input a new authentication code based on a communication with a navigation client 200 that is prohibited by the server arithmetic processing element 110 from accessing the navigation server 100.

Claims

1. A navigation server, comprising a server communication device, a server authentication arithmetic processing element, and a server storage element to store data, wherein

the server storage element is configured to associate an authentication code specific to a user of a navigation client mounted to a user vehicle and first information specific to the user that is received from the navigation client via the server communication device for storage,

the server communication device is configured to recognize the authentication code that is input last time at the navigation client based on a communication with the navigation client,

the server authentication arithmetic processing element is configured to, when the navigation client meets a first condition that the authentication code recognized by the server communication device is stored in the server storage element, permits the navigation client to access the navigation server, and when the navigation client meets a second condition that is determined based on past communication contents with the navigation client before the authentication code is input last time at the navigation client, prohibit the navigation client from accessing the navigation server,

when the navigation client is permitted to access the navigation server by the server authentication arithmetic processing element, the server communication device makes the navigation client recognize the first information that is associated with the authentication code of the user of the navigation client and is stored in the server storage element,

when the navigation client is prohibited from accessing the navigation server by the server authentication arithmetic processing element, the server communication device makes the navigation client output a message urging to input the authentication code of the user of the navigation client, and determines whether or not to permit the navigation client to access the navigation server depending on the input authentication code,

wherein the first information includes second information that is specific to the user, which is collected by the navigation client,

wherein the second information includes information of a parking position and a parking duration of the user vehicle, and

wherein the second condition is at least one of conditions including:

a condition that a parking position where the user vehicle is parked most frequently or for a longest time, which is shown in the second information received from the navigation client during a predetermined first duration is different from a parking position where the user vehicle is parked most frequently or for a longest time, which is shown in the second information received from the navigation client during a predetermined second duration that is different form the first duration, and a condition that a plurality of parking positions where the user vehicle is parked frequently or for a long time among parking positions of the user vehicle that are shown in the second information received from the navigation client during a predetermined third duration are all different from parking positions where the user vehicle is parked that are shown in the second information received from the navigation client during a predetermined fourth duration that is different from the third duration.

2. The navigation server according to claim 1, wherein

the server storage element is configured to associate in advance the authentication code of the user with an evaluation cumulative value of the user that is accumulated when the navigation client is used, for storage,

the server authentication arithmetic processing element is configured to select a service that the user can use in accordance with the evaluation cumulative value of the user, and

the server communication device is configured to make the navigation client output access information to make a notification of the service.

3. The navigation server according to claim 2, wherein

the server authentication arithmetic processing element is configured to make the navigation client output a message urging to input the authentication code even when the second condition is not met in a communication via the server communication device, and also to add, to the evaluation cumulative value, an evaluation value corresponding to a new input of the authentication code when the second condition is not met, and store a resultant to the server storage element.

4. The navigation server according to claim 1, wherein

the second condition is at least one of conditions including:

a condition that a predetermined fifth duration has passed since the authentication code is input at the navigation client last time, which is specified based on past communication contents with the navigation client; and

a condition a sixth duration has passed since an access is made to the navigation server from the navigation client last time, which is specified based on past communication contents with the navigation client.

5. The navigation server according to claim 1, wherein

the server communication device is configured to recognize the authentication code and the first information based on communication with the navigation client, and

the server storage element is configured to associate the authentication code and the first information, which are recognized by the server communication device, for storage.
