Biometric Authentication Apparatus for Multi-User Permission Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small- to medium-sized businesses face difficulties in implementing authentication systems due to high introduction and maintenance costs, as well as the burden of managing user permissions, which can hinder business operations if not properly managed.
Innovation Solution
An information processing apparatus that includes a face detection module, operation module, and main body control module, which captures images to extract biometric information and determines if multiple individuals are present, allowing specific instructions to be executed only when different biometric information is detected, thereby simplifying user authentication and permission management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication systems are implemented in small- to medium-sized businesses, then security and user verification are improved, but introduction costs and maintenance costs increase significantly
Solution Approach 1:
The patent replaces traditional mechanical authentication systems (physical security tokens, manual permission management) with a biometric-based optical authentication system. The image obtaining unit captures images, and biometric information is extracted and compared automatically, eliminating the need for physical authentication devices and manual permission tracking, thereby reducing system complexity while maintaining security
Solution Approach 2:
The patent uses image copying and biometric feature extraction from captured images to create a digital representation of user identity. Instead of requiring physical presence or physical tokens, the system creates and compares biometric copies (facial features, iris patterns, etc.) from images, simplifying the authentication mechanism while maintaining reliability
2Reliability
If traditional authentication systems are implemented in small- to medium-sized businesses, then user verification capability is improved, but the burden of managing user permissions increases
Solution Approach 1:
The patent implements self-service authentication where the system automatically performs biometric verification and permission checking without requiring manual intervention. The determination unit automatically compares biometric information and determines authentication results, eliminating the need for administrators to manually manage user permissions and verify identities
Solution Approach 2:
The patent establishes a feedback loop where the determination unit continuously compares biometric information against stored data and provides automatic authentication decisions. The permission unit receives this feedback and automatically grants or denies access, creating a closed-loop system that eliminates manual permission management while maintaining verification capability
3Speed
If biometric authentication is performed using captured images, then authentication speed is improved, but the requirement for image processing and analysis increases
Solution Approach 1:
The patent extracts only the essential biometric features from captured images rather than processing entire images. The extraction unit identifies and extracts specific biometric information (facial landmarks, iris patterns, fingerprint features) from the image data, reducing processing complexity while maintaining authentication speed by focusing only on relevant features
Solution Approach 2:
The patent segments the authentication process into distinct stages: image capture, biometric feature extraction, feature comparison, and authentication decision. This segmentation allows each component to be optimized independently, with the extraction unit handling only feature identification and the determination unit handling only comparison logic, reducing overall processing complexity while maintaining speed

AI summary
An information processing apparatus includes an instruction accepting unit, an obtaining unit, an extraction unit, a determination unit, and a permission unit. The instruction accepting unit is configured to accept an instruction from a user. The obtaining unit is configured to obtain an image. The extraction unit is configured to extract first biometric information and second biometric information from the image obtained by the obtaining unit. The determination unit is configured to determine whether the first biometric information and the second biometric information are different. The permission unit is configured to permit execution of the instruction accepted by the instruction accepting unit in a case where the determination unit determines that the first biometric information and the second biometric information are different.
