Face Authentication Gate Control via Server Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gate control systems face challenges in securely managing personal information and simplifying face authentication processes for users entering and leaving facilities, particularly in managing face image data and ensuring secure storage and processing.
Innovation Solution
A gate open/close control device and method that utilizes a face authentication server for processing face authentication requests, including a face image acquirer, transmitter, receiver, and controller to manage the gate's open/close status based on authentication results, with options for secure power supply and temporary storage of face images to prevent long-term data retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If face image data is stored locally in the gate device for authentication, then authentication speed is improved, but data security and privacy protection deteriorate
Solution Approach 1:
The patent extracts the face image data storage function from the gate device and relocates it to a dedicated server system. The gate device only retains authentication logic, while face images are stored and managed externally on the server, which implements proper security measures for sensitive data protection.
Solution Approach 2:
The patent introduces a server as an intermediary between the gate device and the face image database. The server acts as a secure mediator that receives authentication requests, retrieves face images, performs comparison, and returns results, thereby protecting both the gate device from data security risks and the database from direct access.
2Device complexity
If a centralized face authentication server is used to store all face images, then data management is simplified, but security risks and vulnerability to attacks increase
Solution Approach 1:
The patent segments the authentication system into multiple independent components: gate devices for local authentication logic, a central server for coordination, and a database for secure storage. This segmentation distributes security responsibilities and reduces the attack surface of any single component.
Solution Approach 2:
The patent implements prior cushioning by designing the system architecture to anticipate and mitigate security threats before they occur. The separated architecture inherently provides defense-in-depth, where even if one component is compromised, the segmented structure prevents complete system breach.
3Ease of operation
If face images are continuously stored in the gate device for repeated authentication, then authentication convenience is improved, but personal information security deteriorates
Solution Approach 1:
The patent extracts sensitive face image data from the gate device's local storage and relocates it to a secure server environment. The gate device maintains only authentication functionality, while personal information is managed externally with proper security controls.
Solution Approach 2:
The patent uses copying by transmitting only necessary authentication data between components rather than storing complete face images locally. The system retrieves and compares face image data from the server when needed, minimizing local data retention and reducing exposure risk.
4Speed
If the gate device performs all authentication processing locally, then response time is improved, but device complexity and processing burden increase
Solution Approach 1:
The patent segments authentication processing into local and remote components. The gate device handles local preprocessing and sends requests to the server, which performs intensive database queries and face comparison. This segmentation reduces the processing burden on the gate device while maintaining overall system speed.
Solution Approach 2:
The patent introduces a server as an intermediary that handles complex authentication processing. The server acts as a dedicated processing unit that manages database access, face image retrieval, and comparison operations, freeing the gate device from these complex tasks while maintaining fast local response for authentication decisions.

AI summary
A gate open/close control device (face authentication machine) includes a face image acquirer (camera) that captures a user before passing through a gate device (external device) and acquires a face image for authentication of the user; a transmitter (communicator) that transmits a processing request for face authentication to the face collation server based on the face image for authentication; a receiver (communicator) that receives the authentication result returned from the face collation server; and a controller that reflects the authentication result on an open/close control signal of the gate device.
