Vehicle Temporary User Biometric Authentication Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle authentication systems require complex fingerprint registration for temporary users and pose a risk of theft as temporary users can access vehicles arbitrarily until their fingerprints are deleted, lacking efficient control authority transfer and theft prevention mechanisms.
Innovation Solution
A vehicle system that includes an input for receiving a temporary user mode command, a detector for acquiring biometric information, and a controller to register and grant authority for vehicle control to temporary users for a predetermined period, allowing access to features like door locking, trunk operation, and ignition control, while deleting the biometric information upon expiration of the set period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint registration is performed for temporary users, then authentication accuracy is improved, but device complexity and operation time increase
Solution Approach 1:
The patent divides user authentication into two distinct segments: permanent users who undergo full fingerprint registration and temporary users who use time-limited authentication codes. This segmentation allows the system to maintain high security for permanent users while providing a simplified, rapid authentication process for temporary users, thus resolving the contradiction between authentication accuracy and registration complexity.
Solution Approach 2:
The patent extracts the biometric verification step from the temporary user authentication process. Instead of requiring fingerprint registration for temporary users, the system uses authentication codes that are verified without biometric data. This extraction eliminates the complexity of biometric registration for temporary users while maintaining authentication reliability through code verification.
2Ease of operation
If temporary user access is allowed without time limits, then ease of operation is improved, but security risk increases
Solution Approach 1:
The patent implements dynamic authentication codes that are valid only for specific time periods or single uses. The controller automatically invalidates these codes after expiration, creating a dynamic security mechanism that maintains ease of operation for authorized temporary users while automatically preventing unauthorized access after the valid period, thus resolving the contradiction between operational convenience and security risk.
Solution Approach 2:
The system takes preliminary anti-action by pre-setting expiration times for temporary user authentication codes. Before any potential security breach can occur, the system has already built in a time limit that automatically revokes access rights. This preliminary measure prevents the harmful effect of unlimited temporary access while maintaining the convenience of easy authentication during the valid period.
3Reliability
If biometric information is stored for temporary users, then authentication reliability is improved, but data security risk increases
Solution Approach 1:
The patent extracts biometric data storage from the temporary user authentication process. Temporary users are authenticated using codes that do not require storing their biometric information in the vehicle's database. This extraction eliminates the data security risk associated with storing temporary users' biometric data while maintaining authentication reliability through code verification and automatic expiration mechanisms.
Data Source
AI summary
A vehicle is provided that includes an input that receives a temporary user mode command from a user and a detector that detects and acquires biometric information of the temporary user. When the temporary user mode command is input from the user a controller registers the biometric information of the temporary user acquired by the detector and grants an authority for access and operation of the vehicle to the temporary user. Thus, the vehicle may more rapidly grant an authority for the use of the vehicle to a temporary user having an intention of temporarily using the vehicle, and since biometric information of the temporary user is deleted when a predetermined period of time has expired, the risk of the theft is reduced.
