Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biometric authentication systems are negatively affected by environmental factors such as noise level, crowdedness, and poor lighting, leading to false negative authentication results and a burdensome user experience.
Innovation Solution
A method that dynamically selects the most suitable biometric authentication method based on device capabilities, environmental conditions, and biometric method strength, using suitability scores to determine the effectiveness of available methods and eliminate unsuitable ones, thereby improving authentication accuracy and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single biometric authentication method is used, then the system is simple to implement, but authentication accuracy deteriorates in unfavorable environmental conditions
Solution Approach 1:
The system dynamically selects biometric authentication methods based on real-time environmental conditions and device capabilities. The processor evaluates suitability factors and generates suitability scores to determine which biometric method (facial recognition, voice recognition, gesture recognition, etc.) is most appropriate for the current situation, making the authentication system adaptive rather than static.
Solution Approach 2:
The system incorporates multiple biometric authentication methods within a single authentication system. By integrating facial recognition, voice recognition, gesture recognition, and other biometric methods, the system can universally handle different authentication scenarios and environmental conditions, selecting the most suitable method for each situation.
2Reliability
If multiple biometric methods are always applied, then authentication accuracy improves, but processing time and system complexity increase
Solution Approach 1:
The system dynamically determines the number and type of biometric methods to apply based on environmental conditions and device capabilities. Rather than always applying all available methods, the processor evaluates suitability factors and selects only the appropriate methods for the current situation, optimizing both accuracy and processing time.
Solution Approach 2:
The system changes the parameters of authentication by adjusting which biometric methods are applied based on suitability scores. The processor can modify the authentication configuration in real-time, selecting subsets of biometric methods that provide sufficient accuracy while minimizing processing time and resource consumption.
3Reliability
If environmental conditions are not considered, then the authentication system is easier to operate, but false negative rates increase
Solution Approach 1:
The system automatically evaluates environmental conditions and device capabilities without requiring user input. The processor autonomously determines suitability factors, generates suitability scores, and selects the appropriate biometric method, making the system self-adjusting and eliminating the need for users to manually configure authentication parameters.
Solution Approach 2:
The system dynamically adapts to environmental conditions by automatically selecting the most suitable biometric authentication method. The processor continuously monitors suitability factors and adjusts the authentication approach in real-time, maintaining high reliability across varying environmental conditions while keeping the user experience simple and seamless.

AI summary
An authentication technique involves obtaining, by processing circuitry, a set of suitability factors from a user device of a user. The authentication technique further involves performing, based on the set of suitability factors and by the processing circuitry, a selection operation which selects a set of suitable biometric methods to apply during authentication from available biometric methods which are available to the processing circuitry for use in authentication. The authentication technique further involves applying, after the set of suitable biometric methods is selected and by the processing circuitry, the set of suitable biometric methods during an authentication operation to determine whether the user is authentic. Accordingly, poorly suited biometric methods can be ruled out (i.e., made unavailable for use by authentication).
