Biometric Authentication Imaging Area Guidance System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in accurately conveying information about the imaging area during biometric authentication, especially when a moving subject is imaged, leading to difficulties in capturing the subject within the imaging area and potentially failing the authentication process.
Innovation Solution
An information presenting system that specifies the position of a biological part used for authentication, sets an imaging area based on this position, and presents information indicating the imaging area at a position allowing overlap with the biological part, thereby guiding the subject to the appropriate imaging area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the imaging area is focused on in advance, then the subject can be captured when passing through the area, but the subject cannot recognize the imaging area in time leading to authentication failure
Solution Approach 1:
The patent applies preliminary action by displaying the imaging area information in advance before the subject approaches the imaging device. The presentation unit shows the imaging area location and guidelines beforehand, allowing the subject to understand and position themselves correctly, thereby ensuring successful authentication without time loss.
Solution Approach 2:
The patent implements feedback by providing real-time visual information about the imaging area through the presentation unit. The system displays the imaging area location and adjusts or refines this information based on the subject's position and characteristics, creating a continuous feedback loop that guides the subject to the correct positioning for successful authentication.
2Ease of operation
If general guidance is provided about the imaging area, then the subject can understand the authentication process, but the information is not accurately conveyed leading to positioning errors
Solution Approach 1:
The patent applies local quality by providing specific, customized imaging area information tailored to each subject's characteristics and position. Instead of generic guidance, the system displays the precise imaging area location and boundaries adjusted to the subject's individual features, ensuring both understanding and accurate positioning.
Solution Approach 2:
The patent uses copying by creating a visual representation of the imaging area through the presentation unit. The system displays a copy or visualization of the imaging area location, boundaries, and guidelines, allowing the subject to clearly see and understand the exact area needed for authentication, thereby eliminating positioning errors.
3Device complexity
If the imaging area is fixed, then the authentication process is simple, but the subject cannot recognize the imaging area when moving leading to capture failure
Solution Approach 1:
The patent applies dynamics by making the imaging area information adaptive and responsive to the subject's position and characteristics. The presentation unit dynamically adjusts the displayed imaging area location and guidelines based on real-time feedback about the subject's position, ensuring the subject can always recognize and position themselves correctly regardless of movement.
Solution Approach 2:
The patent implements feedback by continuously monitoring the subject's position and characteristics, then adjusting the imaging area information display accordingly. This feedback mechanism ensures the subject can always recognize the correct imaging area location, maintaining high reliability even when the subject is moving or has unique physical characteristics.

AI summary
An information presenting system includes: a specification unit that specifies a position of a biological part used for authentication from information about a target person; a setting unit that sets an imaging area in which the biological part is imaged, in accordance with the specified position of the biological part; and a presentation unit that presents information indicating the imaging area at a position that allows an overlap of the biological part. According to this information presenting system, information about biometric authentication can be appropriately presented to the target person, so that an authentication process can be performed normally.
