Biometric Vehicle Authentication Without Prior Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric authentication systems for vehicle entry and ignition often require prior registration, which can be cumbersome and discourage user adoption, and lack efficient methods to authenticate users without physical keys or fobs.
Innovation Solution
A vehicle system that uses a biometric scanner to generate a token, allowing ignition without prior registration by associating the token with authorized users through a keypad entry and secondary authentication methods, such as key fob or mobile device presence, and tracks usage to mark tokens as authorized based on distance, time, and frequency thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior registration is required for biometric authentication, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs preliminary actions by tracking usage patterns, geolocation data, and temporal information in advance to build a confidence score before final authentication is required. This preliminary data collection and analysis enables the system to make authorization decisions without requiring prior explicit registration, thus maintaining security while improving ease of operation.
Solution Approach 2:
The system implements self-service by automatically collecting and analyzing usage data, geolocation information, and temporal patterns without requiring user intervention for registration. The biometric authentication system serves itself by using the vehicle's existing sensors and data collection capabilities to perform background verification, eliminating the need for separate registration processes while maintaining security.
2Ease of operation
If traditional key fob systems are used, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The system replaces the mechanical key fob system with a biometric authentication system that uses optical, capacitive, or other biometric sensors to detect and verify user identity. This substitution eliminates the physical key fob while providing enhanced security through unique biometric characteristics, maintaining ease of operation through contactless or minimal-contact authentication.
Solution Approach 2:
The system changes the authentication parameter from physical presence of a key fob to biometric characteristics such as fingerprint patterns, facial features, or iris structure. This parameter change enables more secure authentication while maintaining or improving ease of operation, as biometric verification can be performed quickly and without physical manipulation of authentication devices.
3Ease of operation
If biometric scanning is implemented without registration, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The system implements feedback by continuously monitoring usage patterns, geolocation data, and temporal information to adjust and refine authentication decisions. The confidence score is dynamically updated based on feedback from multiple data sources, allowing the system to maintain high measurement precision even without prior registration by using real-time contextual information to verify biometric matches.
Solution Approach 2:
The system achieves universality by using a multi-functional authentication approach that combines biometric scanning with usage pattern analysis, geolocation verification, and temporal validation. This multi-functionality allows the system to compensate for the lack of prior registration by cross-validating multiple data sources, thereby maintaining measurement precision while enabling immediate ease of operation.
Data Source
AI summary
Method and apparatus are disclosed for biometric authentication for a vehicle without prior registration. An example vehicle include a biometric scanner to generate a biometric token and a body control module. The body control module when the biometric token is authorized, enable san ignition switch. Additionally, when the biometric token is not authorized and an additional source of authorization is received, the body control module (a) tracks usage of the vehicle subsequent to receiving the biometric token, and (b) marks the biometric token as authorized when the usage satisfies a threshold.
