Dual Authentication With Biometric Fallback for Reader Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems and authentication methods lack high-performance and adaptability, particularly in verifying the legitimacy of access requests to structures like buildings.
Innovation Solution
A dual authentication system using a personal electronic device with both biometric and secret data-based procedures, where the device communicates securely with a reader to authenticate users, ensuring multiple identifiers are associated with the same user and allowing seamless integration with existing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single authentication procedure is used, then the system is simple to operate, but the security level is insufficient
Solution Approach 1:
The system dynamically selects between biometric and secret data-based authentication procedures based on the situation. The electronic device can switch between using biometric data (fingerprint, face recognition) and secret data (password, PIN) depending on security requirements and user preferences, making the authentication system flexible and adaptive rather than static
Solution Approach 2:
The authentication system is divided into two independent procedures: a first procedure using biometric data and a second procedure using secret data. Each procedure can be independently selected and executed, allowing the system to segment the authentication process into manageable parts that can be combined based on security needs
2Reliability
If multiple authentication procedures are implemented, then the security level increases, but the ease of operation decreases
Solution Approach 1:
The system automatically manages the selection between different authentication procedures without requiring user intervention. The electronic device itself determines which authentication method to use based on pre-configured rules, security policies, or situational context, eliminating the need for users to manually choose between biometric or secret data authentication
Solution Approach 2:
The system pre-configures multiple authentication procedures and establishes selection criteria in advance. During authentication, the system automatically applies the pre-established rules to select the appropriate procedure, eliminating the need for users to think about or decide which method to use at the moment of authentication
3Reliability
If a new authentication system is deployed, then the security performance improves, but the adaptability to existing systems decreases
Solution Approach 1:
The authentication system is designed to support multiple authentication procedures (biometric and secret data-based) within a single framework, making it universally applicable to different security requirements and existing infrastructure. The system can function with either procedure independently or in combination, allowing integration with various existing authentication systems while maintaining enhanced security capabilities

AI summary
The present description concerns a method of authentication of a user, to a reader, using a system having the reader and an electronic device having a first biometric authentication procedure and a second authentication procedure. The method includes the following successive steps: using the first procedure to authenticate the user, if the authentication is a success, sending a first identifier associated with the first procedure to the reader to authenticate the user, and if the authentication is not a success, using the second procedure to authenticate the user to the reader by sending a second identifier associated with the second procedure to the reader.
