摘要： A car sharing system includes a car sharing device. The car sharing device includes a key function unit and a user authentication function unit. The key function unit allows a device of a vehicle that is shared with multiple people to operate by performing ID verification through a process similar to an electronic key of the vehicle. When the device of the vehicle is operated with a mobile terminal, the user authentication function unit obtains key information from an external device via the mobile terminal and performs authentication of the key information. When authentication of the key information is accomplished and use of the vehicle is within a reservation time, the user authentication function unit validates the key function unit. The key information is generated as information that is permitted only a temporary use.

摘要： The car sharing system includes a car share device and an encryption code updating unit. The car share device is configured to perform wireless communicate with a mobile terminal that is operable as a vehicle key. The encryption code updating unit updates a first encryption code, which was used during a previous connection of the mobile terminal and the car share device, to a second encryption code, which differs from the first encryption code, when the mobile terminal and the car share device are reconnected.

摘要： An electronic key registration system includes an electronic key and a communication master. The electronic key transmits a registration code. The communication master receives the registration code from the electronic key, code, obtains key information using the registration code, and registers the key information. The registration code is set in accordance with the communication master to which the electronic key is registered. The communication master includes a level determination unit, which determines a key registration security level when the electronic key is registered to the communication master, and a registration execution unit, which obtains the key information using the registration code based on the determined key registration security level and registers the key information to the communication master.

摘要： A car sharing system includes a car share device and a communication control unit. The car share device is configured to perform wireless communication with a mobile terminal that is operable as an electronic key. The communication control unit controls the wireless communication between the mobile terminal and the car share device so that an authentication process through bidirectional communication is executed only when a communication connection establishment process is performed. After the wireless communication has been established, the communication control unit controls the wireless communication so that actuation of an on-board device is permitted in accordance with operation of the mobile terminal through unidirectional communication from the mobile terminal to the car share device.

摘要： An immobilizer ECU transmits a vehicle ID code and a SEED code, which is read from an electronic key, to a data center online. The data center generates an encryption key from the received SEED code and a first logic, and generates a further SEED code from the encryption key, the vehicle ID code, and a second logic. The immobilizer ECU obtains the further SEED code online from the data center, generates the encryption key from the obtained further SEED code, the vehicle ID code, and the second logic, and stores the encryption key.

摘要： An electronic key registration system includes a controller of a communication subject, an initial electronic key that communicates with the communication subject and has an initial encryption key generation code, an additional electronic key that communicates with the communication subject, and an information center including an additional encryption key. The initial electronic key holds an initial encryption key generated from the initial encryption key generation code and a logic. The controller holds the logic and identification information of the communication subject. The controller acquires the initial encryption key generation code from the initial electronic key, generates an initial encryption key from the initial encryption key generation code and the logic held by the controller, and stores the initial encryption key. The information center sends the additional encryption key to the additional electronic key or the controller through a network.

摘要： A partial image is cropped from a photographed image and is displayed on monitors as an image for viewing. When altering the viewing range by altering the cropping position of the partial image cropped from the photographed image, if the position of the partial image is altered as far as an end portion of the photographed image, which forms a limit to the movement of the cropping position, then a belt-shaped image (for example, a belt-shaped image formed by a red line or the like) is added to the image for viewing in the portion of the partial image that corresponds to the movement limit, and the resulting image for viewing is displayed.
