Vehicle Identifier Transfer via Secure OEM-Service Channels

The patent applies preliminary action by pre-calculating and storing authentication data (hash values, salt values, or public keys) in the vehicle's control unit before actual authentication is needed. During runtime, the authentication process only requires retrieving and comparing these pre-prepared values rather than performing intensive calculations, thus maintaining security while reducing computing intensity.

The patent implements self-service by enabling the vehicle's control unit to automatically transmit authentication data and user identification to the service provider's server. The system autonomously handles the linking of vehicle identifiers to user accounts without requiring manual user intervention, thereby improving convenience while maintaining security through cryptographic protection of the transmitted data.

The patent applies universality by utilizing the existing telematics communication infrastructure already present in modern vehicles for transmitting authentication data. Instead of creating separate dedicated transmission channels, the system leverages the multi-functional telematics unit that already handles various vehicle communications, thus improving security through encrypted transmission without significantly increasing device complexity.
