Remote Vehicle Authentication Without In-Car Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for remote vehicle system access, such as requiring a VIN entry for confirmation, are inadequate for vehicles without screens or visual interfaces, posing a safety risk due to potential hacking vulnerabilities.
Innovation Solution
A system and method that receive remote vehicle identification information and a user-confirmable vehicle variable value, allowing access upon user-input matching the remotely received values, enabling secure access through non-visual interfaces like button presses or voice commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If VIN entry and screen confirmation method is used, then remote access security is improved, but vehicles without screens cannot access remote systems
Solution Approach 1:
The patent introduces a remote computing system as an intermediary between the user and the vehicle system. This mediator receives the VIN from the user, communicates with the vehicle to obtain confirmation values, and facilitates the authentication process without requiring a screen in the vehicle. The intermediary handles the complex verification logic and enables vehicles without screens to participate in the secure access protocol.
Solution Approach 2:
The patent replaces the mechanical/visual screen-based confirmation system with alternative input methods. Instead of requiring users to view and confirm information on a vehicle screen, the system accepts user input through other means (such as mobile device interfaces) and verifies authentication through computational comparison of confirmation values, substituting the visual display mechanism with a different interaction paradigm.
2Measurement precision
If screen-based confirmation is required, then user verification accuracy is improved, but operation complexity increases for vehicles without visual interfaces
Solution Approach 1:
The vehicle system automatically generates and transmits confirmation values to the remote computing system without requiring user intervention to display or manipulate these values on a screen. The system performs self-verification by comparing the user-provided confirmation value against the remotely received value, eliminating the need for manual screen interaction while maintaining verification accuracy.
Solution Approach 2:
The confirmation mechanism is designed to work across multiple vehicle types and interface configurations. By using universal communication protocols and accepting confirmation inputs through various channels (mobile apps, voice commands, other input devices), the system maintains verification accuracy while being adaptable to different operational contexts, including vehicles without traditional screens.
Data Source
AI summary
A system includes a processor configured to receive remote vehicle identification information and a user-confirmable vehicle variable value from a remote vehicle computing system. The processor is also configured to receive vehicle identification information and user-confirmable variable value user-input, input in conjunction with a remote process remote access request. Further, the processor is configured to compare the user-input variable value to the remotely received variable value. The processor is additionally configured to provide access to the remote process upon a correspondence between the user-input variable value and the remotely received variable value.
