Vehicle User Authentication Using Face and Driving Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle authentication systems face a trade-off between convenience and crime prevention, with high threshold values degrading convenience and low threshold values compromising security, particularly in cases of vehicle theft.
Innovation Solution
A vehicle theft determination apparatus that utilizes biological information acquisition and driving feature analysis, employing multiple threshold values for face authentication and driving habit recognition to verify user authenticity, ensuring both convenience and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a high threshold value is set for face authentication determination, then crime preventive performance is enhanced, but convenience is degraded
Solution Approach 1:
The patent applies dynamics by making the authentication threshold value changeable based on the vehicle's location. The threshold is dynamically adjusted to be higher at locations with high theft risk (enhancing security) and lower at locations with convenient access needs (improving convenience), resolving the contradiction between fixed security requirements and variable convenience needs
Solution Approach 2:
The patent changes the threshold parameter of face authentication based on geographical location data. By modifying this critical parameter according to pre-stored location information and theft risk levels, the system achieves both high security where needed and high convenience where appropriate
2Ease of operation
If a low threshold value is set for face authentication determination, then convenience is improved, but crime preventive performance is degraded
Solution Approach 1:
The system dynamically adjusts the authentication threshold based on location context. At locations with low theft risk, the threshold is lowered to improve convenience, while at high-risk locations, it is raised to maintain security, thus resolving the contradiction between convenience and crime prevention
3Reliability
If face authentication sample information is passed to third persons through photographs or images, then unauthorized access may occur, but strict authentication reduces such risks
Solution Approach 1:
The patent applies local quality by implementing different authentication strictness levels for different locations. At locations where the user frequently parks or has legitimate access, the system allows more convenient authentication (lower threshold), while at other locations, stricter authentication is applied, thus balancing security and convenience locally

AI summary
[Problem to be Solved] To realize both convenience and crime preventive performance in authentication of a user of a vehicle. [Solution] A vehicle theft determination apparatus 1 includes: a biological information acquisition unit 10 that acquires biological information of a user of a vehicle; a determination unit 30 that determines that the user is an authorized person in a case in which a first biological information similarity between acquired first biological information of the user and biological information registered in advance is equal to or greater than a first threshold value; and a driving feature acquisition unit 20 that acquires driving features of the user who drives the vehicle, the biological information acquisition unit acquiring second biological information of the user if a driving feature similarity between the driving features acquired by the driving feature acquisition unit and driving features registered in advance is equal to or greater than a predetermined value in a case in which the first biological information similarity is less than the first threshold value, the determination unit determining that the user is the authorized person in a case in which a second biological information similarity between the second biological information and biological information registered in advance is equal to or greater than a second threshold value that is less than the first threshold value.
