Biometric Authentication Device With Predictive Registration Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biometric authentication devices experience increased processing loads and delayed authentication results due to frequent updates of registration data, especially in large-scale systems with concentrated authentication requests.
Innovation Solution
An authentication device that includes a registration data storage unit, an authentication unit, an authentication history storage unit, a prediction unit, and an updating unit, which predicts periodic temporal variations in authentication success rates and updates registration data only when the future rate is likely to fall below a threshold, thereby reducing unnecessary processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If registration data is updated frequently with input data to improve authentication rate, then authentication rate is improved, but processing load increases and authentication response is delayed
Solution Approach 1:
The patent applies preliminary action by updating registration data before authentication failure occurs. The prediction unit analyzes temporal variations in authentication rates and proactively triggers updates when a downward trend is detected, rather than waiting for authentication failures. This prevents the system from entering a low-performance state while avoiding reactive update cycles that would increase processing load.
Solution Approach 2:
The patent implements dynamics by making the registration data update mechanism adaptive and dynamic. The prediction unit continuously monitors authentication rates and adjusts update timing based on detected temporal patterns. This dynamic approach allows the system to optimize between maintaining high authentication rates and minimizing processing load, rather than using fixed update intervals.
2Measurement precision
If registration data is updated with every successful authentication to maintain accuracy, then authentication accuracy is improved, but processing load increases significantly
Solution Approach 1:
The patent applies partial action by performing registration data updates only when necessary, based on predicted temporal variations in authentication rates. Instead of updating with every successful authentication (excessive action), the system selectively updates only when the prediction unit detects a downward trend, reducing processing load while maintaining sufficient authentication accuracy.
Solution Approach 2:
The patent implements feedback through the prediction unit that continuously monitors authentication rates and uses this information to control when updates occur. The authentication rate serves as feedback that informs the update decision, creating a closed-loop system that adjusts processing intensity based on actual performance needs, thereby reducing unnecessary processing load.

AI summary
Provided are an authentication device, an authentication system, and an authentication method, which are capable of increasing an authentication rate while suppressing an increase in a processing load. To solve this problem, the authentication device acquires a periodic temporal variation of an authentication rate, using history information stored in an authentication history storage unit storing a previous authentication result as history information, predicting whether or not a future authentication rate is lower than a previous value, based on the temporal variation of the authentication rate, and updates registration data regarding biometric information which has been registered, using input data regarding biometric information input from a user, when it is predicted that a future authentication rate will be lower than a predetermined value.
