Vehicle Door Control Using Face Authentication and Gestures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door operation systems require electronic keys for unlocking and lack user-friendly contactless opening and closing capabilities, and are vulnerable to relay attacks.
Innovation Solution
An information processing apparatus that performs biometric authentication and gesture determination using captured images to control vehicle door unlocking and other operations contactlessly, allowing user-specific control signals based on registered identities and gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric authentication and gesture determination are implemented for contactless door control, then user-friendliness is improved, but device complexity increases
Solution Approach 1:
The patent combines biometric authentication (face recognition) and gesture determination into a single integrated control system. The image processing apparatus performs both functions using captured images, merging multiple authentication methods into one unified device that controls door unlocking and opening operations simultaneously.
Solution Approach 2:
The information processing apparatus serves multiple functions: it performs biometric authentication to identify users, determines gestures to detect user intent, and controls both unlocking and opening of doors. This multi-functional system replaces traditional separate key-based unlocking and button-based opening mechanisms.
2Reliability
If electronic keys are required for unlocking, then security is improved, but ease of operation deteriorates due to relay attack vulnerabilities
Solution Approach 1:
The patent replaces the electronic key system (prone to relay attacks) with a biometric authentication system using face recognition. This substitutes the mechanical/electronic key-based approach with a biological characteristic-based system that is inherently more secure and enables true contactless operation without vulnerability to signal interception.
3Ease of operation
If gesture determination is added for door opening control, then user-friendliness is improved, but measurement precision requirements increase
Solution Approach 1:
The system performs biometric authentication first to verify the user's identity before enabling gesture-based door opening control. This preliminary authentication step ensures that only authorized users can perform gestures to open doors, reducing the precision requirements for gesture recognition by establishing a trusted user context beforehand.

AI summary
An information processing apparatus includes a first authentication unit, a first vehicle controlling unit, a gesture determining unit, and a second vehicle controlling unit. The first authentication unit controls biometric authentication of a person included in a first captured image, and determines whether the person included in the first captured image is a registered user. The first vehicle controlling unit, if the person included in the first captured image is determined to be a registered user, transmits a first control signal for executing first control. The gesture determining unit controls a gesture determination of whether a gesture of a person included in a second captured image is a registered gesture. The second vehicle controlling unit, if the gesture of the person included in the second captured image is a registered gesture, transmits a second control signal for executing second control.
