Biometric Authentication Server Load Reduction via Collation Order Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric authentication systems face significant processing burdens and inefficiencies due to the need for one-to-N authentication, where the server manages usage time and frequency data, leading to increased server load and ineffective collation order management across different installation locations.
Innovation Solution
A service providing device extracts biometric information from living body image data and transmits it along with collation order information to a biometric authentication server, which prioritizes authentication based on historical service usage patterns to reduce processing time and server burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the biometric information authentication server manages usage time and usage frequency data to optimize collation order, then authentication speed is improved, but server burden and complexity increase
Solution Approach 1:
The patent extracts the collation order management function from the biometric information authentication server and relocates it to the service providing device. The service providing device now manages usage time and usage frequency data locally, creating collation order information that is transmitted to the server. This extraction reduces server complexity while maintaining authentication speed improvements through optimized collation ordering.
Solution Approach 2:
The patent introduces collation order information as an intermediary element between the service providing device and the biometric information authentication server. This intermediary carries usage pattern data that guides the server's authentication process, allowing the server to optimize authentication speed without directly managing usage data, thus reducing server burden while improving performance.
2Adaptability or versatility
If one-to-N authentication is performed with a large number of registered users, then authentication coverage is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and transmitting collation order information from the service providing device to the biometric information authentication server before authentication occurs. This collation order is based on usage time and usage frequency data, allowing the server to prioritize template comparison in an optimized sequence, thus reducing processing time while maintaining comprehensive authentication coverage across all registered users.
3Device complexity
If collation order is managed monotonously across all devices, then system simplicity is improved, but effectiveness of authentication optimization decreases
Solution Approach 1:
The patent implements local quality by allowing each service providing device to independently manage its own collation order information based on local usage patterns. Each device can optimize authentication ordering according to its specific installation location and usage characteristics, improving overall authentication efficiency while maintaining simple standardized protocols for communication between devices and the server.
