Certified User-Selectable Control Configuration for Vehicle Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle service tools lack effective mechanisms to restrict access to certain functions based on user certification credentials, potentially leading to unauthorized use or damage during servicing, and do not adequately prevent unauthorized starting of vehicles without a key or key fob.
Innovation Solution
A computing system that determines and configures user-selectable controls based on user credentials, enabling or deprecating functions accordingly, ensuring only certified users can perform specific tasks, such as servicing high-voltage systems or accessing vehicle security systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access restrictions based on user certification credentials are implemented, then vehicle security and safety are improved, but user interface complexity and device complexity increase
Solution Approach 1:
The user interface is segmented into multiple control types (first controls for certified functions, second controls for non-certified functions). This segmentation allows the system to manage complexity by organizing controls into distinct categories based on certification requirements, thereby improving security while maintaining interface structure.
Solution Approach 2:
The user interface dynamically adapts its configuration based on the user's certification credentials. The system automatically determines which controls to display, enable, or disable based on real-time credential verification, reducing the need for manual configuration and managing complexity through automated adaptation.
2Ease of operation
If all functions are made accessible in the user interface, then ease of operation is improved, but unauthorized access and potential damage increase
Solution Approach 1:
Different controls within the user interface have different accessibility qualities based on user credentials. Certified controls are accessible to all users, while restricted controls are only accessible to certified users. This local differentiation ensures ease of operation for common functions while preventing unauthorized access to sensitive functions.
Solution Approach 2:
The system introduces an intermediary credential verification mechanism that mediates between the user and the controls. The processor acts as an intermediary, automatically verifying credentials and determining control accessibility, thereby protecting against unauthorized use without requiring manual security checks that would reduce ease of operation.
3Reliability
If certification verification is performed for each control, then access security is improved, but processing time and system complexity increase
Solution Approach 1:
The system performs preliminary credential verification when the user first accesses the computing system or user interface. This preliminary action establishes the user's certification status in advance, allowing subsequent control accessibility decisions to be made quickly without repeated full verification processes, thereby reducing verification time while maintaining security.
Solution Approach 2:
The credential verification system serves multiple functions: it determines overall user authentication status, identifies specific certification levels, and controls access to multiple different controls simultaneously. This multi-functionality reduces the need for separate verification processes for each control, minimizing processing time while maintaining comprehensive access security.

AI summary
A method comprising determining a user interface (e.g., a GUI) selected to be used at a computer includes a user-selectable control (USC) corresponding to a certified user function (CUF). The computer includes program instructions executable to perform the CUF. The method includes determining whether a user identifier, received at the computer, corresponds to a certification credential for the CUF. The method also includes configuring the USC based on whether the user identifier corresponds to the certification credential. Configuring the USC includes enabling the USC if the user identifier corresponds to the certification credential, or deprecating the USC if the user identifier does not correspond to the certification credential. Enabling the USC configures the USC to be usable to trigger execution of the program instructions to perform the CUF. Deprecating the USC configures the USC to be unusable to trigger execution of the program instructions to perform the CUF.
