Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user authentication methods become inconvenient as the complexity of authentication numbers increases, compromising security and reliability while requiring users to remember complex codes.
Innovation Solution
A terminal device and method that simultaneously inputs biometric data, such as fingerprints and irises, alongside authentication numbers, by dynamically changing the input region on a display unit to facilitate easier and more accurate recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of digits of the authentication number is increased or a mixer of numbers, letters or special symbols is used, then security is strengthened, but user inconvenience increases
Solution Approach 1:
The patent combines authentication number input with biometric data input (fingerprint, iris) into a unified authentication process. Users can simultaneously provide both types of authentication information through integrated input regions, merging two separate authentication methods into one coordinated action that strengthens security without increasing operational burden
Solution Approach 2:
The authentication system is designed to accept multiple types of authentication information (authentication numbers and biometric data) through the same interface and processing mechanism. The input regions can handle different authentication modalities universally, allowing the system to flexibly process various authentication methods without requiring separate dedicated interfaces for each type
2Measurement precision
If biometric data input region is fixed, then device structure is simple, but recognition accuracy decreases
Solution Approach 1:
The patent implements dynamic input regions that can change their boundaries, size, and position based on the type of biometric data being captured. The controller adjusts the input region parameters in real-time according to the detected biometric data type, allowing the system to optimize the capture area for each specific biometric modality while maintaining a relatively simple overall device structure
3Measurement precision
If multiple input regions are provided for different biometric data types, then recognition accuracy is improved, but user operation complexity increases
Solution Approach 1:
The patent divides the authentication interface into multiple input regions, each optimized for specific biometric data types. This segmentation allows each region to be tailored for maximum recognition accuracy of its intended biometric modality while maintaining clear visual separation that guides users on where to place different types of biometric data
Solution Approach 2:
Instead of requiring users to select which input region to use based on the biometric data type, the system automatically detects the biometric data type and directs it to the appropriate input region. This inversion of the selection logic from user-driven to system-driven simplifies user operation while maintaining the benefits of multiple specialized input regions
Data Source
