Multi-Biometric Authentication System for Identity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric authentication systems face challenges when unchangeable biometrics are compromised, as users cannot easily reset or change them, and changeable biometrics like text-dependent voice passwords require remembering secret information, which is burdensome.
Innovation Solution
A computing device uses a multi-biometric authentication system to verify identity with both unchangeable and changeable biometrics, providing security metadata to the user if the changeable biometric is not verified correctly, allowing for secure access without remembering the metadata.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If unchangeable biometric authentication is used, then security is improved, but user flexibility and ability to recover from compromise is worsened
Solution Approach 1:
The system dynamically switches between unchangeable biometric authentication (for high security) and changeable biometric authentication (for flexibility and recovery). The authentication method is not fixed but adapts based on system state and user needs, allowing the system to leverage both unchangeable and changeable biometrics at different times.
Solution Approach 2:
The system changes the parameter of biometric changeability by using two different types of biometrics with opposite characteristics. The unchangeable biometric provides stable security, while the changeable biometric allows flexibility. The system manages both types simultaneously, changing the authentication approach rather than the biometric itself.
2Adaptability or versatility
If changeable biometric authentication is used, then user flexibility is improved, but security is worsened due to requirement of remembering secret information
Solution Approach 1:
The authentication system is segmented into two independent parts: unchangeable biometric authentication and changeable biometric authentication. Each part handles different aspects of the authentication requirements. The unchangeable part handles security-critical scenarios, while the changeable part handles flexibility needs, and they can be used separately or in combination.
Solution Approach 2:
The system introduces an intermediary mechanism that manages both unchangeable and changeable biometric authentication methods. This intermediary coordinates between the two authentication types, allowing the system to leverage the strengths of both while mitigating their individual weaknesses.
3Adaptability or versatility
If multiple biometric authentication methods are used, then authentication flexibility is improved, but system complexity is worsened
Solution Approach 1:
The authentication system is designed with multi-functionality to handle both unchangeable and changeable biometric authentication methods within a single unified framework. The system can perform multiple authentication functions (face recognition, voice recognition, password verification) through a common authentication architecture, reducing the need for separate independent systems.

AI summary
Techniques for leveraging multiple biometrics for enabling user access to security metadata are provided. In one embodiment, a computing device can receive first and second biometric identifiers from a user. The computing device can further determine, via a multi-biometric authentication system, that the user's identity can be verified using the first biometric identifier, but cannot be, or has not been, verified using the second biometric identifier. In response to this determination, the computing device can provide information to the user for facilitating verification of the user's identity using the second biometric identifier.
