The present disclosure provides an information management system capable of solving a problem related to handling of information regarding each driver when a plurality of drivers drives one vehicle. An information management system 1 according to an aspect of the present disclosure manages driver information DI regarding a driver of a vehicle V. The information management system 1 includes a driver identification unit 111 that acquires personal identification information PI of the driver, an information acquisition unit 12 that acquires driver information DI including travel information of the vehicle V, and individual information storage units 125 and 132 that store individual information PD in which the personal identification information PI and the driver information DI are associated with each other.

Claims (25)

1 . An information management system that manages driver information regarding a driver of a vehicle, the system comprising:

a driver identification unit that acquires personal identification information of the driver;

an information acquisition unit that acquires the driver information including travel information of the vehicle; and

individual information storage unit that stores individual information in which the individual identification information and the driver information are associated;

a communication unit that is able to communicate with an outside of the vehicle;

a secret key storage unit that stores unique secret key for each piece of personal identification information; and

an electronic signature unit that electronically signs the individual information by using the secret key unique to the individual identification information associated with the individual information,

wherein the communication unit transmits the identification information to which the electronic signature is attached to the outside of the vehicle.

2 . The information management system according to claim 1 , further comprising:

a hardware security module that includes the secret key storage unit and the electronic signature unit.

3 . The information management system according to claim 1 , wherein, when an activation switch of the vehicle is turned off, the individual information stored in the individual information storage unit is erased.

4 . The information management system according to claim 3 , wherein the individual information is transmitted to the outside of the vehicle via the communication unit before the individual information is erased.

5 . The information management system according to claim 1 ,

wherein, when an activation switch of the vehicle is turned off, the individual information is stored in a nonvolatile storage area of the individual information storage unit, and

when the activation switch of the vehicle is turned on, the individual information stored in the nonvolatile storage area of the individual information storage unit is transmitted to the outside of the vehicle via the communication unit, and is erased.

6 . The information management system according to claim 1 , wherein the driver identification unit acquires the personal identification information transmitted from an electronic key of the vehicle or a mobile information terminal owned by the driver.

7 . The information management system according to claim 1 , further comprising:

a public key generation unit that generates a public key corresponding to the secret key unique to each piece of personal identification information,

wherein the communication unit transmits the public key to an outside.

8 . An information management system that manages driver information regarding a driver of a vehicle, the system comprising:

a driver identification unit that acquires personal identification information of the driver;

an information acquisition unit that acquires the driver information including travel information of the vehicle; and

individual information storage unit that stores individual information in which the individual identification information and the driver information are associated,

wherein the driver identification unit includes an authentication information acquisition unit that acquires biometric information of the driver, an authentication information storage unit that stores the biometric information and the personal identification information in association with each other, and a collation unit that collates the biometric information acquired by the authentication information acquisition unit with the biometric information stored in the authentication information storage unit, and

in a case where the biometric information acquired by the authentication information acquisition unit and the biometric information stored in the authentication information storage unit coincide, the collation unit acquires the individual identification information associated with the coincided biometric information from the authentication information storage unit.
