Vehicle Fingerprint Reset via On-Board Diagnostics Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fingerprint-based vehicle access and starting systems, when a new owner takes over, they may not know the password set by the former owner, leading to difficulties in resetting the registered fingerprint data, which can result in security vulnerabilities and potential theft.
Innovation Solution
A fingerprint data reset system and method that utilizes on-board diagnostics to communicate with various electronic control units in a vehicle, allowing for the transmission of a fingerprint reset request signal and enabling the fingerprint authentication control module to determine if the user input is from the vehicle's owner, thereby resetting the registered fingerprint data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint authentication control module requires password verification for resetting registered fingerprint data, then security is improved, but ease of operation deteriorates when new owner does not know the password
Solution Approach 1:
The on-board diagnostics system serves as an intermediary between the user and the fingerprint authentication control module. It provides an alternative authentication pathway through vehicle identification number (VIN) verification, mediating the reset process when the original password is unavailable. This intermediary mechanism resolves the contradiction by offering a backup authentication method that maintains security while improving ease of operation for legitimate owners.
Solution Approach 2:
The system changes the authentication parameter from password-based verification to VIN-based verification for the reset process. By altering the authentication parameter rather than maintaining a single fixed method, the system allows legitimate owners to reset fingerprints through vehicle identification even when they don't remember the password, thus resolving the contradiction between security and ease of operation.
2Adaptability or versatility
If multiple authentication methods are implemented for fingerprint reset, then adaptability is improved, but device complexity increases
Solution Approach 1:
The on-board diagnostics system is designed with multi-functionality, serving both as a diagnostic tool and as an authentication mechanism for fingerprint reset. By making the existing on-board diagnostics system universal rather than creating a separate dedicated reset system, the patent implements multiple authentication methods while minimizing the increase in device complexity.
3Ease of operation
If on-board diagnostics is used for fingerprint reset, then ease of operation is improved, but reliability may deteriorate due to potential unauthorized access
Solution Approach 1:
The system performs preliminary authentication through VIN verification before allowing the fingerprint reset operation. This preliminary action ensures that only authorized users can initiate the reset process, maintaining security while enabling ease of operation through the on-board diagnostics interface. The preliminary verification step prevents unauthorized access while simplifying the reset process for legitimate owners.
Data Source
AI summary
A fingerprint data reset system that may reset registered fingerprint data through an on-board diagnostics includes: a vehicle including a first controller configured to authenticate input fingerprint data based on comparison between the input fingerprint data and registered fingerprint data; and the on-board diagnostics configured to communicate with a plurality of controllers of the vehicle through an in-vehicle communication network of the vehicle, wherein the on-board diagnostics is configured to transmit a fingerprint reset request signal to the first controller among the plurality of controllers based on receiving a user input for resetting the registered fingerprint data, and the first controller is configured to determine whether the user input is received from a user of the vehicle based on the fingerprint reset request signal, and reset the registered fingerprint data based on a determination that the user input is received from the user of the vehicle.
