Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices often experience high authentication failure rates or are unable to perform authentication methods when the user's context or device environment is unfavorable, leading to suboptimal security and user experience.
Innovation Solution
An adaptive authentication method that dynamically selects and adjusts authentication techniques based on the device's usage environment, function executed, and authentication level, utilizing a combination of biometric sensors and a processor to optimize authentication methods for successful user verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specified authentication method is performed regardless of context, then authentication security is maintained, but authentication failure rate increases and user experience deteriorates
Solution Approach 1:
The patent implements dynamic authentication method selection based on real-time context information. The system automatically adjusts the authentication method being executed according to the current usage environment, device state, and function being accessed, rather than using a fixed authentication approach. This resolves the contradiction by making the authentication system adaptable to different situations while maintaining security requirements.
Solution Approach 2:
The system changes authentication parameters (method type, complexity level) based on context variables such as usage environment, device state, and function importance. By dynamically adjusting these parameters, the system achieves both high security for critical functions and high success rate for routine operations, resolving the contradiction between security and ease of operation.
2Device complexity
If a fixed authentication method is used, then system complexity is reduced, but adaptability to different usage environments deteriorates
Solution Approach 1:
The patent segments the authentication process into multiple independent methods (e.g., fingerprint, iris, pattern recognition) that can be selectively executed. Each authentication method operates as an independent module, allowing the system to choose the appropriate method based on context without increasing overall system complexity. This segmentation enables environmental adaptability while maintaining manageable system complexity.
Solution Approach 2:
The authentication system is designed with multi-functionality, supporting multiple authentication methods within a single unified framework. This universal design allows the system to adapt to different usage environments by selecting from available methods, achieving high versatility without proportionally increasing complexity through standardized interfaces and centralized control.
3Ease of operation
If authentication methods are selectively adjusted based on context, then authentication success rate improves, but device complexity increases
Solution Approach 1:
The system implements feedback mechanisms that monitor context information (usage environment, device state, function type) and automatically adjust authentication method selection accordingly. This feedback loop enables the system to achieve high authentication success rates by learning from and adapting to contextual patterns, while the automated nature of the feedback process prevents excessive complexity increase through intelligent rather than brute-force adaptation.
