Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unsecured or improperly secured vehicles are susceptible to unauthorized access, leading to potential risks and distractions, while existing authentication methods may not adequately prevent unauthorized use or expose sensitive data.
Innovation Solution
A data processing system with a digital assistant application that employs multi-factor authentication using sensors and audio-based inputs to determine entry events and access permissions, ensuring secure and hands-free control of vehicle functionalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-factor authentication is implemented using multiple sensors and authentication credentials, then vehicle security is improved, but device complexity increases
Solution Approach 1:
The authentication system is divided into multiple independent authentication factors (biometric authentication, device authentication, location authentication) that can be implemented and verified separately. Each factor uses different sensors and credentials, allowing the system to achieve high security through cumulative verification while maintaining modularity that manages complexity.
Solution Approach 2:
The patent implements nested authentication where multiple authentication credentials are verified in hierarchical layers. The system first verifies basic entry credentials, then progressively verifies additional authentication factors (biometric data, device identifiers, location information) nested within each other, achieving comprehensive security through layered verification.
2Ease of operation
If audio-based hands-free control is used for authentication, then driver distraction is reduced, but authentication precision may be affected
Solution Approach 1:
The system merges multiple authentication modalities (audio-based voice commands, biometric authentication through sensors, device authentication) into a unified authentication process. This combination allows hands-free operation while compensating for the limitations of individual modalities, maintaining high authentication accuracy through multi-factor verification.
Solution Approach 2:
The system uses intermediary authentication mechanisms where audio-based commands serve as the initial interface for hands-free operation, but actual authentication is mediated through additional verification layers including biometric sensors and device credentials, ensuring accuracy while maintaining ease of operation.
