Biometric Signature Authentication for Password-Free Identity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional identity authentication methods relying on passwords are inconvenient for users and vulnerable to theft, posing security risks.
Innovation Solution
Implement biometric authentication using fingerprint information, where biometric data is collected, verified against preset information, and used to digitally sign service requests, with a digital signature certificate private key, and verified by a server using the corresponding public key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If password-based authentication is used, then the system is simple to implement, but the user must memorize passwords which causes inconvenience and security risks
Solution Approach 1:
The patent replaces the mechanical/password-based authentication system with a biometric authentication system using fingerprint recognition. The fingerprint sensor captures biometric data, which is then processed and compared against stored templates to authenticate users, eliminating the need for password memorization while enhancing security through unique biological characteristics.
Solution Approach 2:
The patent creates digital copies of biometric characteristics (fingerprint patterns) and stores them as authentication templates. These copied biometric features are then used for verification without requiring the user to physically present their finger each time, as the system compares captured biometric data against the stored digital copy.
2Reliability
If biometric authentication is implemented, then security and convenience are improved, but the device complexity increases
Solution Approach 1:
The patent integrates the biometric authentication functionality directly into the mobile device by combining the fingerprint sensor, processing unit, and storage components into a unified authentication module. This merging of components streamlines the system architecture and reduces overall complexity despite adding biometric capabilities.
Solution Approach 2:
The biometric authentication system operates autonomously by automatically capturing fingerprint data, processing it through template matching algorithms, and making authentication decisions without requiring manual intervention. The system self-manages the authentication workflow, reducing the operational complexity for users.
Data Source
AI summary
A service request is received by a terminal device. First biometric authentication information of a user associated with the service request is collected. The first biometric authentication information is compared with preset biometric authentication information. When the comparison shows that the first biometric authentication information and the preset biometric authentication information are consistent, a pre-stored digital signature certificate private key is read. The service request is digitally signed according to the digital signature certificate private key. A biometric information verification message is generated and sent message to a server. The server is configured to read a pre-stored digital signature certificate public key corresponding to the digital signature certificate private key. Authentication result information is receiving from the server after the server verifies and signs the biometric information verification message according to the digital signature certificate public key.
