Adaptive Fingerprint Authentication System for Dynamic Swipe Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fingerprint authentication systems face inefficiencies due to the need for multiple reauthentications and limitations in handling finger swipe directions, particularly when the sensor orientation changes or the user switches hands, leading to computational inefficiencies and compromised performance.
Innovation Solution
A method and system that dynamically adjusts the default finger swipe scan direction based on received scan data, changing it if a predetermined number or percentage of scans differ from the default, allowing for adaptive authentication regardless of sensor orientation or user hand changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system attempts fingerprint match in multiple directions to accommodate reverse swiping, then authentication reliability is improved, but computational performance deteriorates due to repeated matching attempts
Solution Approach 1:
The system performs preliminary detection of finger swipe direction before attempting fingerprint matching. By detecting the swipe direction in advance and rotating the scan data accordingly, the system prepares the data in the correct orientation before matching begins, eliminating the need for multiple matching attempts and thereby improving computational performance while maintaining authentication reliability.
2Productivity
If the system only allows single-direction swiping to simplify authentication, then computational performance is improved, but adaptability deteriorates when sensor orientation changes or user switches hands
Solution Approach 1:
The system dynamically adjusts the default finger swipe scan direction based on detected swipe patterns. By learning and adapting to the user's preferred swipe direction over time, the system maintains high computational performance while becoming adaptable to different sensor orientations and user preferences, resolving the contradiction between speed and versatility.
3Reliability
If the system rotates scan data by 180 degrees for reverse direction matching, then authentication reliability is improved, but processing time increases due to additional rotational operations
Solution Approach 1:
The system performs the data rotation operation in advance, during the initial detection phase, before the matching process begins. By rotating the scan data to the correct orientation beforehand, the system eliminates the need for time-consuming rotation operations during the critical matching phase, thereby reducing overall processing time while maintaining authentication reliability.
