Biometric Identity Verification Using Wireless Auxiliary Factor Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identity identification methods are not convenient for users as they require manual input of both biometric features and auxiliary identification factors, making the process cumbersome and time-consuming.
Innovation Solution
A method where a biometric feature collection device broadcasts a wireless signal to establish a mapping relationship between an auxiliary identification factor and an identity, allowing a mobile device to upload the auxiliary identification factor to an identification server before the user enters the identification area, enabling two-factor-based identity identification without the need for manual input during the identification process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input of auxiliary identification factor is required during identity identification, then security is improved through two-factor authentication, but user convenience deteriorates and identification time increases
Solution Approach 1:
The patent applies preliminary action by having the mobile device automatically upload the auxiliary identification factor to the server before the actual identity identification occurs. The mapping relationship between the auxiliary identification factor and biometric feature is established in advance, so during identification, only the biometric feature needs to be collected and matched, eliminating the need for manual auxiliary factor input while maintaining security
2Reliability
If manual input of auxiliary identification factor is required during identity identification, then authentication accuracy is maintained, but identification speed deteriorates
Solution Approach 1:
The auxiliary identification factor is uploaded and mapped to the biometric feature in advance through preliminary action. During the actual identification process, the system only needs to perform biometric feature matching against the pre-established mapping relationship, significantly accelerating identification speed while maintaining authentication accuracy through the retained two-factor verification mechanism
3Reliability
If two-factor authentication is implemented, then security is improved, but system complexity increases due to additional input requirements
Solution Approach 1:
The patent applies self-service by enabling the mobile device to automatically upload the auxiliary identification factor and establish the mapping relationship without user intervention. The system autonomously manages the complexity of two-factor authentication setup and verification, reducing the perceived system complexity for users while maintaining security
Solution Approach 2:
The patent introduces a server as an intermediary that stores and manages the mapping relationship between auxiliary identification factors and biometric features. This intermediary handles the complexity of two-factor authentication logic, allowing the biometric feature collection device to focus solely on biometric data collection and matching, thereby simplifying the overall system architecture
Data Source
AI summary
Identity identification preprocessing methods and systems, and identity identification methods and systems are disclosed. After any user carries a mobile device to a predetermined nearby area of a biometric feature collection device, the mobile device of the user receives a wireless signal broadcast by the biometric feature collection device. The wireless signal triggers the mobile device to upload an auxiliary identification factor other than a biometric feature of the owner and an identity of the owner to an identification server. The identification server establishes a mapping relationship between the received identity and the received auxiliary identification factor. After subsequently obtaining a collected biometric feature uploaded by the biometric feature collection device, the identification server can perform two-factor-based user identity identification based on the previously established mapping relationship and the collected biometric feature.
