Dynamic Biometric Fusion for Verification Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric verification technologies face challenges due to environmental conditions such as temperature, illumination, and humidity, leading to misrecognition or misidentification, highlighting the need for a method that can effectively combine multiple biometric modalities to enhance verification accuracy and reliability.
Innovation Solution
A user verification method that sets termination stages for multiple biometric verifiers based on specific criteria, including application type, security level, and sensing environment, to generate and fuse outputs from various biometric modalities like fingerprints, faces, and irises, using a fusion model to produce a final verification result.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single biometric verifier is used, then the verification process is simple and fast, but the accuracy and reliability are reduced due to environmental conditions
Solution Approach 1:
The patent combines multiple biometric verifiers (fingerprint, face, iris) into a unified verification system. Each verifier processes different biometric modalities and their results are fused to produce a final verification decision, thereby improving reliability through diversity while managing complexity through structured integration
2Reliability
If multiple biometric verifiers are executed completely, then the verification accuracy is improved, but the verification time increases
Solution Approach 1:
The patent implements dynamic termination of biometric verifier execution based on intermediate results. The verification process can be stopped early if certain conditions are met (e.g., one verifier already provides sufficient confidence), allowing the system to adapt execution depth to each specific case and reduce average verification time while maintaining accuracy
Solution Approach 2:
The system dynamically adjusts verification parameters such as termination stages and fusion strategies based on environmental conditions, security requirements, and intermediate verification results. This allows optimization of the balance between accuracy and speed for each verification attempt
3Reliability
If the termination stage is set high for all verifiers, then the false acceptance rate is reduced, but the verification speed decreases
Solution Approach 1:
The patent applies different termination stage settings to different biometric verifiers based on their individual characteristics, reliability, and suitability for the current verification context. Rather than uniformly setting high termination stages for all verifiers, the system selectively adjusts parameters for each verifier to optimize the overall balance between false acceptance rate and verification speed

AI summary
A user verification apparatus may perform user verification using multiple biometric verifiers. The user verification apparatus may set a termination stage of one or more biometric verifiers. Multiple biometric verifiers may be used to generate outputs, for which separate termination stages are set to establish a particular combination of set termination stages associated with the multiple biometric verifiers, and the user verification apparatus may fuse outputs of the biometric verifiers based on the particular combination of set termination stages. The user verification apparatus may verify a user based on a result of the fusing, and an unlocking command signal may be generated based on the verifying. The unlocking command signal may be generated to selectively grant access, to the verified user, to one or more elements of a device. The device may be a vehicle.
