Vehicle Telematics Authentication Using Dual Smart Security Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telematics service subscription processes for vehicles are inefficient, requiring human intervention and lacking secure authentication of ownership, leading to potential privacy and security issues, especially when transferring ownership or providing services to subsequent owners.
Innovation Solution
A method using two smart security devices, such as keys or fobs, to authenticate and pair with a vehicle's telematics system, ensuring only authorized owners can access and utilize telematics services, eliminating the need for human intervention in service activation and transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional telematics service subscription processes are used, then service activation can be achieved, but human intervention is required and security is compromised
Solution Approach 1:
The system enables automatic service activation and ownership transfer through the telematics control unit's autonomous authentication process. The TCU independently verifies ownership using the two smart security devices without requiring human intervention from service providers or manual configuration, allowing the system to self-service the subscription activation and transfer processes.
Solution Approach 2:
The patent replaces manual mechanical processes (human intervention in service activation) with an automated electronic authentication system. The two smart security devices communicate electronically with the TCU through the vehicle's communication bus, substituting the mechanical/manual subscription process with an automated digital verification and activation sequence.
2Productivity
If wireless service is pre-provisioned for vehicles, then service availability is improved, but costs increase due to inactive service provisioning
Solution Approach 1:
The system performs preliminary authentication verification through the two smart security devices before activating wireless service. This preliminary action ensures that service is only provisioned when genuine ownership is confirmed, preventing wasteful provisioning for vehicles that will remain inactive or are subject to unauthorized use, thereby reducing unnecessary wireless service costs.
Solution Approach 2:
The authentication system provides feedback verification through the two smart security devices to confirm genuine ownership before service activation. This feedback mechanism ensures that wireless service is only activated when properly authorized, preventing wasteful provisioning and enabling cost-effective service delivery by matching activation with verified ownership status.
3Ease of operation
If ownership transfer is simplified, then ease of operation is improved, but security and privacy are compromised
Solution Approach 1:
The ownership verification process is segmented into two separate authentication factors represented by the two smart security devices. This segmentation requires possession of both devices for successful authentication, providing enhanced security while maintaining ease of operation through automatic verification. The segmented approach prevents unauthorized transfer while enabling legitimate owners to easily complete the process.
Solution Approach 2:
The two smart security devices act as intermediaries between the owner and the telematics system during ownership transfer. These intermediary devices provide secure authentication by verifying ownership through the vehicle's communication bus without exposing sensitive information, enabling both secure verification and ease of operation through automated processing.

AI summary
A vehicle processing device authenticates that an authorized user has requested an action by the vehicle and generates an authentication acknowledgement message. At least two security devices being present within the cabin of, or close to, the vehicle during a predetermined period following an authentication trigger event that occurs while the user performs a predetermined sequence of authentication activities (i.e., button presses, operating the vehicle or a part of it, etc.) provides a basis for the authentication acknowledgement message. Typically, information unique to each security device has been associated with the vehicle at a service provider's server. The authentication acknowledgement may include an activation code that results from processing the information, unique to each security device, received from the security devices and other random information, such as date. A service provider's server, or a user device, provides services to, or can access, respectively, the vehicle upon receiving the authentication acknowledgement.
