Biometric Verification Object Specifier for Abnormal Region Exclusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric authentication systems face accuracy issues due to changes in the biometric information source, such as wounds, diseases, or environmental factors, which can occur during registration or verification, leading to reduced authentication reliability.
Innovation Solution
A verification object specifying apparatus that detects abnormal portions in the biometric information source and determines whether to include or exclude them from the verification process, using a processor and memory to store and analyze biometric information, and employing sensors to capture images for vein recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication is performed using biometric information from the biometric information source part, then authentication can be conducted, but authentication accuracy deteriorates when abnormal portions (wounds, diseases, etc.) are present in the source part
Solution Approach 1:
The patent divides the biometric information source part into multiple regions and identifies abnormal portions within these regions. By segmenting the source part, the system can selectively exclude abnormal regions while retaining normal regions for authentication, thus maintaining accuracy despite the presence of abnormalities.
Solution Approach 2:
The patent extracts and removes abnormal portions from the biometric information source part. By taking out the abnormal regions (wounds, diseases, etc.), the system creates a cleaned-up biometric data set that excludes harmful factors, thereby maintaining authentication accuracy.
2Reliability
If the entire biometric information source part is used for verification, then verification process is simple, but verification reliability decreases due to temporary or permanent changes in the source part
Solution Approach 1:
The patent performs preliminary detection of abnormal portions before the verification process. By detecting and identifying abnormal regions in advance, the system can prepare a modified verification object that excludes these regions, ensuring reliable verification without requiring complex real-time adjustments during the verification process.
3Reliability
If abnormal portions are detected and excluded from verification, then authentication accuracy improves, but the verification process becomes more complex
Solution Approach 1:
The patent implements a self-service mechanism where the system automatically detects, identifies, and excludes abnormal portions without requiring manual intervention. The verification object specifying apparatus autonomously processes the biometric information, detecting abnormalities and creating appropriate verification objects, thereby reducing the need for complex manual verification procedures.
Data Source
AI summary
In a verification object specifying apparatus that specifies a verification object for biometric authentication, a biometric information acquisition unit acquires biometric information from a biometric information source part. An abnormality detection unit detects an abnormal portion in the biometric information source part based on the biometric information. A verification object specifying unit determines whether biometric information located in the abnormal portion is to be included in a verification object, and specifies biometric information to be used as the verification object based on the determination result. The verification object specifying apparatus causes a registration unit to register the biometric information as registration information when serving as a registration apparatus, and causes a verification unit to verify the biometric information against registration information when serving as a verification apparatus.
