Authentication Terminal Distance-Based Biometric Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems, such as those described in Patent Literature 1, require users to manually select and transmit data for passing through automatic gates, which reduces convenience as the required data can vary by location and time, leading to user inconvenience.
Innovation Solution
An authentication terminal and system that acquires first and second biometric information of a user at specific distances, uses this information for matching processing, and requests necessary authentication data from the user's terminal to determine service provision, thereby automating the authentication process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the automatic gate uses fixed authentication data, then the system is simple to operate, but it cannot adapt to different locations and time periods
Solution Approach 1:
The mobile phone automatically performs the authentication data selection and transmission process without requiring user intervention. The terminal autonomously determines which authentication data to use based on the service type and transmits it to the authentication terminal, eliminating the need for users to manually select data while enabling adaptation to different locations and time periods through centralized control
2Adaptability or versatility
If the mobile phone stores multiple types of authentication data, then it can serve different locations and time periods, but the user must manually select the correct data
Solution Approach 1:
The authentication terminal provides feedback to the mobile phone regarding the service type and required authentication data format. The mobile phone receives this feedback information and automatically selects the appropriate authentication data from its stored data, eliminating the need for manual user selection while maintaining the capability to provide different authentication data for different locations and time periods
3Productivity
If the authentication process requires manual user selection, then the system maintains security through user control, but it reduces operational efficiency
Solution Approach 1:
The mobile phone pre-stores multiple types of authentication data in advance, organized by service type and location. When authentication is required, the system quickly retrieves the appropriate pre-prepared data based on feedback from the authentication terminal, enabling fast authentication processing without requiring real-time user decision-making or manual selection

AI summary
An authentication terminal includes a first acquisition unit, a second acquisition unit, a control unit, and an authentication processing unit. The first acquisition unit acquires first biometric information of a user from another apparatus when a distance between own terminal and the user reaches a first distance. The second acquisition unit acquires second biometric information of the user when the distance between own terminal and the user reaches a second distance. The control unit performs control to acquire data for authentication from a terminal possessed by the user, which is necessary to determine whether or not to provide a service to the user. The authentication processing unit determines that an authentication processing of the user is successful when a result of the matching processing using the first biometric information and the second biometric information is successful and the data for authentication acquired from the terminal is valid.
