Fingerprint Enrollment ID Generation Using Time and Location Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fingerprint enrollment systems, the same finger can be recognized as corresponding to multiple different fingerprint IDs due to variations in fingerprint regions, leading to payment failures and reduced efficiency in fingerprint recognition.
Innovation Solution
A method for fingerprint enrollment that compares an enrolled fingerprint image with a preset template, generating a new fingerprint ID based on current time and geographical location information when a match is not found, ensuring that fingerprint images from the same finger are mapped to the same ID, thereby reducing recognition failures and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fingerprint images from the same finger are stored with multiple different IDs due to variations in fingerprint regions, then the system can accommodate more fingerprint variations, but the recognition accuracy decreases and payment failures increase
Solution Approach 1:
The patent applies parameter changes by incorporating temporal (current time) and spatial (current geographical location) parameters into the fingerprint ID generation process. When a fingerprint image is enrolled, the system generates a unique ID that includes these contextual parameters, ensuring that the same finger enrolled at different times or locations receives the same consistent ID, thereby resolving the recognition accuracy issue while maintaining adaptability to fingerprint variations
2Adaptability or versatility
If multiple fingerprint IDs are stored for the same finger, then the system can handle fingerprint region variations, but the device complexity and storage requirements increase
Solution Approach 1:
Instead of storing multiple separate fingerprint templates with different IDs, the patent changes the parameter structure of the ID itself by embedding time and location information. This allows the system to handle fingerprint region variations by generating consistent IDs through parameter-based differentiation rather than through multiple storage entries, thereby reducing device complexity and storage requirements
Solution Approach 2:
The patent uses a virtual copy approach by generating fingerprint IDs that represent the same physical fingerprint through different contextual parameters (time and location) rather than creating actual duplicate storage copies. This virtual differentiation through parameter copying reduces the need for multiple physical storage entries while maintaining the ability to handle variations
3Ease of operation
If traditional fingerprint enrollment is used without time and location parameters, then the enrollment process is simpler, but payment failures occur due to inconsistent ID recognition
Solution Approach 1:
The patent enhances the traditional simple enrollment process by automatically incorporating time and location parameters into the ID generation without requiring additional user input or complex manual procedures. This automatic parameter integration maintains ease of operation while significantly improving payment success rates by ensuring consistent ID recognition across different enrollment and verification instances
Data Source
AI summary
A method for fingerprint enrollment, a terminal, and a non-transitory computer readable storage medium are provided. The method includes the following. An enrolled fingerprint image is acquired. The enrolled fingerprint image is compared with a preset fingerprint template. Fingerprint ID of the preset fingerprint template is determined as fingerprint ID of the enrolled fingerprint image when the enrolled fingerprint image matches the preset fingerprint template. New fingerprint ID is generated as the fingerprint ID of the enrolled fingerprint image when the enrolled fingerprint image fails to match the preset fingerprint template.
