Vehicle Mobile Device Pairing Authentication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for pairing a vehicle with a mobile device lack sufficient security mechanisms, allowing unauthorized devices to pair with the vehicle during the pairing process, leading to inconvenience for the owner.
Innovation Solution
A method and system that implement multiple confirmation mechanisms, including a power switch, physical buttons, and a display, to ensure secure pairing authentication between a vehicle and a mobile device, using a vehicle identification code and pairing code displayed on both devices, with double confirmation and automatic pairing functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth pairing procedure is implemented without deliberate communication mechanism, then ease of operation is improved, but security is worsened allowing unauthorized pairing
Solution Approach 1:
The patent introduces an intermediary verification mechanism where a pairing code is generated and displayed on both the vehicle display and mobile device screen. This intermediary element serves as a mediator to confirm that the pairing request is authorized by the vehicle owner, preventing unauthorized pairing while maintaining ease of operation through automatic code comparison.
2Reliability
If multiple confirmation mechanisms are implemented, then security is improved, but device complexity is worsened
Solution Approach 1:
The patent utilizes existing multi-functional components (display screen, processor, communication module) to perform multiple functions including showing pairing codes, comparing codes, and establishing Bluetooth connections. This approach improves security through multiple confirmation mechanisms while avoiding increased device complexity by leveraging already-present universal components.
3Productivity
If automatic pairing is implemented, then productivity is improved, but security is worsened due to lack of user confirmation
Solution Approach 1:
The patent implements a feedback mechanism where the system automatically generates a pairing code and displays it on both the vehicle and mobile device, then compares the codes to confirm authorization. This feedback loop enables automatic pairing (improving productivity) while ensuring security through user-visible code confirmation, resolving the contradiction between speed and authorization reliability.

AI summary
A method for pairing authentication between a vehicle (1) and a mobile device (3) is proposed. After a host computer (21) of the vehicle (1) is operated to send out a vehicle identification code for pairing and the mobile device (3) is operated to select the vehicle identification code, the host computer (21) enables both of a host display (22) of the vehicle (1) and the mobile device (3) to display a pairing code at the same time. After a pairing procedure is performed within a predetermined pairing operation period, the host computer (21) completes pairing authentication between the host computer (21) and the mobile device (3).
