Abstract
A storage device stores authentication information as information related to a digital key of a vehicle. An execution device acquires from a server located outside of the vehicle contract information that indicates whether a valid contract that allows the digital keys to be used exists. The execution device deletes information related to the digital key that the storage device stores on a condition that the acquired contract information indicates that the valid contract does not exist.
Claims8
An in-vehicle device comprising:
- a storage device and processing circuitry, wherein
- the storage device stores information related to a digital key of a vehicle, and
- the processing circuitry is configured to execute deletion control including:
- acquiring contract information from outside the vehicle, in which the contract information indicates whether there is a valid contract allowing the digital key to be used, and
- on condition that the acquired contract information indicates that the valid contract does not exist, deleting the information related to the digital key from the storage device.
A method executed by an in-vehicle device that stores information related to a digital key of a vehicle, the method comprising:
- acquiring, with the in-vehicle device, contract information, from outside the vehicle, indicating whether a valid contract allowing the digital key to be used exists;
- and
- deleting, with the in-vehicle device, the information related to the digital key from the in-vehicle device on condition that the acquired contract information indicates that the valid contract does not exist.
A non-transitory computer-readable medium storing a program executed by an in-vehicle device storing information related to a digital key of a vehicle, wherein when the program is executed by the in-vehicle device, the program causes the in-vehicle device to perform operations comprising:
- acquiring contract information, from outside the vehicle, indicating whether there is a valid contract allowing the digital key to be used, and
- deleting the information related to the digital key from the in-vehicle device on condition that the acquired contract information indicates that the valid contract does not exist.
