Face Authentication Using Communication Terminals for Construction Site Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for managing entrance and exit at construction sites require the installation of a face authentication apparatus at the gate, making it inefficient to manage the entry and exit of individuals.
Innovation Solution
An information processing apparatus that registers face information of users associated with specific places, acquires position information and face data from communication terminals, performs user authentication by comparing the acquired face data with registered data, and records successful authentication for entrance or exit purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a face authentication apparatus is installed at the gate of a construction site, then user authentication can be performed, but the system complexity and installation requirements increase
Solution Approach 1:
The patent uses a communication terminal (smartphone) as an intermediary device to perform face authentication. The terminal captures the user's face image, transmits it to the server for authentication, and receives the authentication result. This mediator approach eliminates the need for complex dedicated authentication hardware at the gate while maintaining reliable authentication functionality.
Solution Approach 2:
The patent replaces the mechanical/physical face authentication apparatus with an information-based system. Instead of using dedicated optical hardware and mechanical gate control systems, the invention uses digital image capture, data transmission, and server-based processing to achieve authentication, thereby simplifying the physical system while improving reliability.
2Reliability
If a dedicated face authentication apparatus is used at the gate, then authentication can be performed, but the ease of operation and accessibility decrease
Solution Approach 1:
The patent leverages the universality of communication terminals that users already possess and are familiar with. The same smartphone used for daily communication is also used for authentication, eliminating the need for specialized equipment. This multi-functional approach improves ease of operation while maintaining authentication reliability through the use of advanced image processing and server-based verification.
3Ease of operation
If face authentication is performed using a communication terminal, then the ease of operation improves, but the measurement precision of face data may be affected
Solution Approach 1:
The system implements feedback mechanisms where the server evaluates the quality of received face images and requests re-capture if the quality is insufficient. The system provides guidance to users on proper positioning and capture conditions, ensuring that even though the terminal is portable and easy to use, the authentication precision is maintained through iterative quality control.
Solution Approach 2:
The system performs preliminary checks on face image quality before proceeding with authentication. The server analyzes received images for adequate resolution, proper framing, and sufficient lighting conditions, and only processes images that meet predetermined quality standards. This preliminary quality assessment ensures measurement precision is maintained despite using portable communication terminals.

AI summary
Entrance and exit of a person is efficiently managed by simple authentication and registration of entrance and exit using a communication terminal carried by the person. An information processing apparatus includes a face information register that registers face information of registered users who are to enter into and exit from a place in association with the place, an information acquirer that acquires, from a communication terminal, position information of the communication terminal, face information of an applying user who applies to enter into or exit from the place, and application information for entering or exiting, a user authenticator that performs user authentication by comparing the face information of the applying user acquired from the communication terminal by the information acquirer with the face information of the registered users registered in the face information register, and an entrance and exit recorder that records, if the user authentication succeeds, that the applying user has entered into or exited from the place corresponding to the position information.
