A recently granted patent (Publication Number: US11886566B2) discloses a vehicle authentication system that includes a ring-type wearable device, an in-vehicle device, and a communication terminal. The ring-type wearable device is worn on a user's finger and has unique identification information, enabling short-range wireless communication with the in-vehicle device and the communication terminal. The in-vehicle device includes an authentication unit, a vehicle-side short-range communication unit, and a reception information acquisition unit. The authentication process is based on verification between the identification information received by the short-range communication module and the identification information acquired by the reception information acquisition unit. Additionally, the system allows for reservations for vehicle use and display of authorized user information on the vehicle's display device.

Furthermore, the patent details various configurations and functionalities of the vehicle authentication system, such as intermittent activation of the vehicle-side short-range communication unit, location of the short-range communication module near vehicle switches operated by the user's finger, and the use of long wave communication for verification requests to portable devices. The system ensures secure and convenient vehicle access by leveraging wearable technology and wireless communication protocols. The in-vehicle device is equipped with an authentication unit, a vehicle-side short-range communication unit, and a reception information acquisition unit, enabling seamless authentication processes based on verification between identification information from the ring-type wearable device and the information acquired by the device. This innovative system enhances user experience and security in vehicle access and operation.
