Decentralized Biometric Authentication System Using Segmented Verification Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric identification systems face challenges in securely collecting and authenticating biometric data, especially in large and widespread groups, as they often require a single consolidated system and are prone to data security issues when data is stored in databases.
Innovation Solution
A method and system where biometric data collection and authentication are conducted on distinct devices, with the verification process capturing and comparing data from biometric identification documents and the authentication process capturing live data, using similarity thresholds for verification and encryption to secure sensitive information, allowing for decentralized storage and secure access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric data is collected and stored in a consolidated database system, then authentication can be performed centrally, but data security risks increase and system flexibility decreases
Solution Approach 1:
The system is divided into multiple independent verification devices, each capable of performing biometric verification locally without requiring a central database. This segmentation eliminates the single point of failure and reduces data security risks associated with centralized storage, while maintaining authentication functionality through distributed computation.
Solution Approach 2:
The patent extracts the biometric verification functionality from a centralized system and implements it as standalone verification devices. Each verification device contains the necessary computational resources to perform complete verification operations independently, removing the dependency on a central database and thereby enhancing data security and system resilience.
2Adaptability or versatility
If a single consolidated system is used for biometric data collection and authentication, then system simplicity is maintained, but adaptability to large and widespread groups is reduced
Solution Approach 1:
The system architecture is segmented into multiple independent verification devices that can be deployed at different locations. This allows the system to scale horizontally by adding more verification devices to handle larger and more widespread groups, while each individual device remains relatively simple and maintains the same functional capabilities.
Solution Approach 2:
Each verification device is designed as a universal platform that can perform multiple functions including biometric data collection, verification, and authentication. This multi-functionality allows the same device type to serve various purposes across different scenarios and locations, enhancing the system's adaptability without requiring complex specialized hardware for each function.
3Reliability
If biometric data is stored in databases for later authentication, then authentication capability is enabled, but data security issues arise from potential unauthorized access
Solution Approach 1:
The patent extracts and eliminates the database storage component from the system architecture. Instead of storing biometric data centrally for later authentication, the system uses verification devices that can perform authentication operations without requiring persistent storage of the biometric data itself, thereby removing the vulnerability surface associated with database breaches.
Solution Approach 2:
The system performs preliminary verification actions at the time of authentication using the verification device, rather than relying on pre-stored data. The verification device can compare live biometric data against reference data or templates without needing to access a database, enabling secure authentication while minimizing data exposure risks through immediate processing and deletion of sensitive information.
Data Source
AI summary
Authentication method and system using biometric data of a person. The method is flexibly usable on a plurality of distinct verification and authentication devices and comprises a verification process and an authentication process. First biometric data is captured by the verification device and compared to official biometric data. Captured and inputted data is certified and stored. At time of a required authentication of the person, live biometric data of the person is captured and compared to first biometric data. If the data is similar, the person is automatically authenticated.
