User Terminal Biometric Authentication via Information Code Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high costs associated with installing cameras for biometric authentication at multiple facilities, such as stores, and the concern of impersonation using pre-stored face image data in existing authentication systems.
Innovation Solution
A user terminal equipped with an imaging device that captures an information code to activate an authentication assistance function, acquires a user's face image, and outputs biometric information for authentication, eliminating the need for separate cameras and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cameras are installed at each facility for biometric authentication, then authentication reliability is improved, but introduction costs increase
Solution Approach 1:
The user terminal performs self-service by capturing its own face image using its built-in imaging device and generating biometric information autonomously. This eliminates the need for external cameras at facilities, as the terminal itself provides the authentication data, resolving the contradiction between reliability and introduction cost.
Solution Approach 2:
The user terminal serves multiple functions: it acts as both the imaging device for capturing face images and the authentication client. This multi-functionality eliminates the need for separate camera installations at each facility, reducing introduction costs while maintaining authentication reliability through the terminal's own imaging capabilities.
2Ease of manufacture
If pre-stored face image data is used for authentication, then introduction costs are reduced, but impersonation risk increases
Solution Approach 1:
The terminal performs preliminary action by capturing the face image and generating biometric information at the time of authentication request, rather than relying on pre-stored data. This ensures the data is current and tied to the actual user present, preventing impersonation while keeping costs low by using the terminal's existing imaging capabilities.
Solution Approach 2:
The patent replaces the mechanical system of storing physical cards or pre-stored image data with a digital biometric information system generated on-demand from the terminal's imaging device. This substitution eliminates impersonation risks associated with pre-stored data while maintaining low introduction costs by utilizing the terminal's built-in capabilities.
3Measurement precision
If separate cameras are installed for face authentication, then authentication accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges the imaging function and authentication client functions into a single user terminal. The terminal's built-in imaging device is combined with its processing capabilities to generate biometric information, eliminating the need for separate camera systems and reducing overall system complexity while maintaining authentication accuracy.
Solution Approach 2:
The user terminal acts as an intermediary between the user and the authentication system. It captures the face image, generates biometric information, and transmits it to the authentication server, eliminating the need for external cameras at facilities. This intermediary role simplifies the overall system architecture while preserving recognition accuracy through the terminal's imaging capabilities.

AI summary
A user terminal includes: an imaging unit that captures an information code including predetermined activation information (e.g., information for activating an authentication assistance function program); an activation unit that activates an authentication assistance function program using the activation information included in the captured information code; an acquisition unit that acquires an image including a face of a user captured by the imaging unit according to the activation of the authentication assistance function program; and an output unit that outputs biometric information of the user based on the image for biometric authentication.
