Assistance Server for Biometric Authentication Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems require costly replacements when switching from card ID to biometric features for user authentication, as they need to change the entire system, including the authentication server and associated applications.
Innovation Solution
An authentication system that includes an assistance server which, upon detecting no registration of biometric information, acquires first authentication data from the authentication server and produces second authentication data associating biometric information with user identification, allowing seamless integration of biometric features without altering the authentication server's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If another authentication system is used (e.g., biometric features instead of card ID), then authentication functionality is improved, but system replacement cost increases
Solution Approach 1:
An assistance server is introduced as an intermediary component between the authentication server and the information processing apparatus. The assistance server stores biometric information and user identification information, and performs the function of matching biometric features with user identities. This intermediary approach allows biometric authentication to be implemented without modifying the existing authentication server, thereby avoiding costly system replacement while achieving improved authentication functionality.
2Adaptability or versatility
If the authentication server is replaced to support biometric authentication, then authentication versatility is improved, but compatibility with existing systems deteriorates
Solution Approach 1:
The authentication function is segmented into two independent parts: the existing authentication server that handles traditional authentication methods (card ID, passwords), and the newly introduced assistance server that handles biometric authentication. This segmentation allows each component to maintain its original functionality independently, ensuring that the authentication server continues to operate as before while the assistance server provides additional biometric authentication capabilities, thus maintaining system compatibility while improving versatility.
3Device complexity
If biometric authentication is implemented without an assistance server, then system complexity is reduced, but authentication flexibility deteriorates
Solution Approach 1:
The assistance server is designed with multi-functionality to handle various authentication scenarios. It can store multiple types of authentication information (biometric information, user identification information), support different matching algorithms, and provide authentication services for multiple information processing apparatuses. This universal design allows the system to maintain low complexity while achieving high authentication flexibility, as the assistance server can adapt to different authentication requirements without requiring changes to the core authentication server.
Data Source
AI summary
Authentication system includes an information processing apparatus, an authentication server and an assistance server, wherein the authentication server, in response to being requested to perform authentication of the user, performs authentication of the user using first authentication data that associates user identification information for identifying a registered user with first authentication information, and the assistance server, in response to detection of no registration of second authentication information that is different from the first authentication information of the user, acquires the first authentication data from the authentication server, and produces second authentication data that associates the second authentication information with the first authentication data.
