Biometrics Authentication Using Group Number Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometrics authentication systems require users to remember unique ID numbers, which is inconvenient and can lead to inefficiencies, especially in large-scale systems where ID numbers are difficult to manage and remember, limiting the effectiveness of biometric authentication in accessing individual information.
Innovation Solution
A biometrics authentication system that uses a detection device to capture biometric characteristics, such as blood vessel patterns, and links them to a group number stored in a database, allowing access to individual information without the need for a unique ID number, simplifying user input and improving convenience by using a group number for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If unique ID numbers are used for biometrics authentication, then individual information can be accurately accessed, but user convenience deteriorates because users must remember and input unique ID numbers
Solution Approach 1:
The patent segments the identification system into two parts: a group number (easy to remember) and an individual identifier (unique within the group). The group number serves as the user-friendly input, while the individual identifier maintains authentication accuracy. This segmentation resolves the contradiction by separating the convenience function from the precision function.
Solution Approach 2:
The patent introduces a database as an intermediary between the group number input and the biometric verification. The database stores the mapping between group numbers and individual identifiers, automatically handling the translation without requiring users to remember unique ID numbers. This intermediary resolves the contradiction by automating the identification process.
2Ease of operation
If ID numbers are made short and simple, then ease of memorization improves, but the possibility of overlapping ID numbers increases
Solution Approach 1:
The patent segments the identification into group-level (simple, memorable) and individual-level (unique) components. The group number can be short and simple for easy memorization, while the individual identifier within the group ensures uniqueness. This segmentation allows both simplicity and reliability to coexist.
Solution Approach 2:
The patent adds a hierarchical dimension to the identification system: first dimension is the group number (simple, memorable), second dimension is the individual identifier within the group (unique). This dimensional expansion allows the system to achieve both ease of memorization and reliability without compromise.
3Loss of information
If biometrics data is stored with unique ID numbers, then individual information can be accurately retrieved, but system complexity increases due to the need to manage numerous unique IDs
Solution Approach 1:
The patent introduces a database as an intermediary that manages the mapping between group numbers and individual identifiers. This database intermediary handles the complexity of maintaining unique identifiers while presenting simple group numbers to users, thus reducing the operational complexity without losing information accessibility.
Solution Approach 2:
The system performs self-service by automatically managing the mapping between group numbers and individual identifiers through the database. The system automatically retrieves the correct individual identifier based on the group number input, eliminating the need for manual ID management and reducing operational complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables accurate and secure individual authentication using easily remembered group numbers, facilitating access to individual information and improving user convenience, even in environments where unique ID numbers are challenging to manage.
Implementation Method 1
Hemoglobin in the red corpuscles flowing in the veins has lost oxygen. This hemoglobin (reduced hemoglobin) absorbs near-infrared rays at wavelengths near 760 nanometers. Consequently when near-infrared rays are made incident on the palm of a hand, reflection is reduced only in the areas in which there are veins
Implementation Method 2
The image capture device uses a sensor to receive near-infrared rays rebounding from the palm of the hand

AI summary
An information processing system using biometrics authentication employ biometrics characteristics for individual authentication to enable accessing of individual information, with which the convenience of input for users is improved. A biometrics database which links and stores group numbers, individual identification numbers, and biometrics data is provided, and a group number is used to read biometrics data for the group, which is verified against detected biometrics data to identify the individual identification number and access an individual database. Even if a user sets a group number which is not easily forgotten, biometrics authentication can be used to execute individual authentication with high accuracy, and moreover secure individual information access is possible.
