Authentication Terminal Biometric Code Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems face challenges in managing biometric authentication history and labor management records due to difficulties in identifying the owner of an information code without recording facial feature points in a database, leading to increased management costs and inefficiencies.
Innovation Solution
An authentication terminal and system that captures body and code images, extracts embedded biometric information from a code symbol, and performs authentication by collating it with body image data, notifying a management apparatus of successful authentication to facilitate easy record-keeping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If facial feature points are recorded in a database for authentication, then authentication accuracy is improved, but management cost and complexity increase due to storage and deletion operations
Solution Approach 1:
The patent extracts only the necessary biometric information (facial feature points) from the captured image and embeds it in the code image, rather than storing complete personal information in a database. This reduces database storage requirements and simplifies management operations while maintaining authentication capability.
Solution Approach 2:
The patent creates a copy of the biometric information by embedding it within the code image itself. This allows the authentication terminal to extract and compare biometric data directly from the code image without needing to retrieve it from a database, eliminating storage and retrieval complexity.
2Device complexity
If biometric information is not recorded in a database, then management cost is reduced, but ability to identify the owner of the information code and manage labor records deteriorates
Solution Approach 1:
The patent merges the biometric information with the identification information by embedding both in the same code image. This combination allows the system to identify the code owner and manage labor records without maintaining separate database storage for biometric data.
Solution Approach 2:
The patent performs preliminary embedding of biometric information into the code image during the code generation phase. This preliminary action ensures that the biometric data is already prepared and embedded in the code image, eliminating the need for subsequent database operations and preserving identification capability without increased management complexity.
3Reliability
If complete personal information is stored in a database, then authentication reliability is improved, but security risk from data breaches increases
Solution Approach 1:
The patent extracts only the essential biometric features needed for authentication and embeds them in the code image, rather than storing complete personal information. This reduction in stored data minimizes security risks while maintaining authentication reliability through the preserved biometric characteristics.
Data Source
AI summary
The image acquisition unit acquires a body image generated by capturing an image of a body of a target person and a code image generated by capturing an image of a code recording medium. The code recording medium includes a code symbol that can be visually recognized and in which embedded information including biometric information for registration of the target person and identification information on the target person are recorded. The embedded information acquisition unit acquires the embedded information from the code image. The authentication unit executes biometric authentication by collating the biometric information for registration included in the embedded information with biometric information for authentication generated based on the body image. The notification unit notifies a management apparatus of the identification information on the target person when the biometric authentication has been successful.
