Vehicle Facial Entry With Secondary Code Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric security systems in vehicles lack an alternative authentication method when biometric identification fails, preventing users from sharing access with others or allowing third-party access without prior enrollment, as they rely solely on individual biometric data.
Innovation Solution
A camera-based vehicle entry system that employs a secondary nonbiometric authentication method using image sensors to capture and analyze alphanumeric codes, gestures, or graphical depictions, allowing access when biometric recognition fails, enabling sharing of access with pre-defined secondary codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric identification system is used, then security level is improved, but flexibility of access sharing is worsened
Solution Approach 1:
The authentication system is segmented into multiple independent pathways: primary biometric authentication (facial recognition) and secondary non-biometric authentication (code-based). This segmentation allows the system to maintain high security through biometric verification while simultaneously providing flexible access sharing through alternative code-based methods that can be communicated to authorized individuals.
Solution Approach 2:
A secondary authentication code acts as an intermediary mechanism between the primary biometric system and the access control function. When biometric authentication is unavailable or fails, this intermediary code enables third-party access without requiring prior enrollment, thus resolving the contradiction between security and access sharing flexibility.
2Reliability
If only biometric authentication is provided, then authentication security is improved, but user convenience is worsened
Solution Approach 1:
The system performs preliminary biometric authentication attempts first, and only when these fail or are not available does it transition to the secondary code-based authentication. This preliminary action maintains security by prioritizing biometric verification while providing a convenient fallback option that does not require complex enrollment procedures.
Solution Approach 2:
Instead of requiring users to enroll third parties in the biometric system (complex process), the system inverts the approach by allowing the primary user to share access through simple code communication. This inversion maintains security while dramatically improving ease of operation for access sharing scenarios.
3Adaptability or versatility
If keypad-based system is used, then access sharing flexibility is improved, but security level is worsened
Solution Approach 1:
The system merges the advantages of both biometric and keypad-based systems by integrating facial recognition technology with code-based authentication. The biometric component provides high security levels, while the code-based component enables flexible access sharing, creating a hybrid system that achieves both goals simultaneously rather than requiring a trade-off.

AI summary
A vehicle entry system which identifies authorized users via facial recognition has an image sensor configured to capture real-time images according to a predetermined field of view from a vehicle. A lockout device is configured to selectably provide access to the vehicle. The entry system has a controller configured to (A) analyze a first one of the captured images for matching to a stored facial pattern corresponding to an authorized user of the vehicle, (B) detect a request for a secondary authentication after the captured image being analyzed fails to match the stored facial pattern, (C) analyze a second one of the captured images for a nonbiometric secondary code entrusted to a secondary user; and (D) issue a command for the lockout device to grant the access to the vehicle when the secondary code is detected.
