Vehicle Entry Support System with Visual Face Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional entry systems fail to prevent internal vehicle users from being startled by externally located persons who suddenly enter the vehicle without the internal user's notice, as they rely solely on iris data matching without providing visual confirmation or authentication.
Innovation Solution
An entry support system that includes internal user recognition, externally located person recognition, reporting, and permission processing, utilizing a display unit to show the externally located person's face image and determining registered user status, allowing internal users to make informed entry decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional entry systems use only iris data matching for authentication, then authentication speed is improved, but safety is worsened because internal users cannot visually confirm externally located persons before entry
Solution Approach 1:
The system provides visual feedback to the internal user by displaying the face image of the externally located person on a display unit before entry permission is granted. This feedback mechanism allows the internal user to confirm the identity of the person seeking entry, resolving the contradiction between fast authentication and safe entry by adding a visual confirmation step without significantly delaying the process
Solution Approach 2:
The system performs preliminary action by acquiring and displaying the face image of the externally located person before the final entry permission is granted. This preliminary visual confirmation step ensures that the internal user can identify the person before they enter the vehicle, improving safety while maintaining authentication efficiency
2Reliability
If the system displays face images of all externally located persons, then entry safety is improved, but device complexity is worsened due to additional recognition and display components
Solution Approach 1:
The system uses a multi-functional approach where the camera unit serves both to capture images for authentication purposes and to capture face images for display purposes. The image processing unit handles both iris recognition and face image preparation, reducing the need for separate dedicated components and thereby limiting the increase in device complexity while maintaining entry safety
3Reliability
If the system requires permission operation for every externally located person, then entry safety is improved, but ease of operation is worsened due to additional authentication steps
Solution Approach 1:
The system implements self-service by allowing the internal user to independently review the face image and make the entry permission decision themselves. The permission unit simply executes the decision made by the internal user without requiring additional external authentication steps, maintaining ease of operation while improving safety through user awareness

AI summary
An entry support system includes: an externally located person reporting unit which executes predetermined reporting by a reporting unit used by an internal user when an externally located person is recognized by an externally located person recognition unit in a state where the internal user is recognized by an internal user recognition unit; and an entry permission unit which executes entry permission processing for enabling entry to a vehicle when a permission operation of the entry to the vehicle is performed to an operation unit used by the internal user after the predetermined reporting is executed.
