Summary
This study introduces a novel contactless fingerprinting system to prevent infectious disease spread. The new biometric authentication achieves high accuracy (97.51%) without physical contact, improving upon existing technologies.
Area of Science:
- Biometrics
- Infectious Disease Control
- Image Processing
Background:
- The COVID-19 pandemic highlights the need for contactless biometric authentication to prevent SARS-CoV-2 transmission.
- Existing contactless fingerprint scanners have limitations including poor image quality and low correlation factors.
Purpose of the Study:
- To develop an improved contactless fingerprinting system addressing current technological limitations.
- To enhance biometric authentication for public health and security.
Main Methods:
- Implemented a system for fixed-distance finger positioning, avoiding physical contact with the device.
- Utilized variable background illumination and 2D imaging techniques for consistent resolution.
- Developed a unique architectural design for convenient contactless fingerprint acquisition.
Main Results:
- Achieved high-precision fingerprint pattern recognition with a correlation factor of up to 97.51%.
- Successfully mitigated issues like perspective distortion, motion blur, and inconstant resolution.
- Demonstrated a convenient and effective contactless fingerprint acquisition process.
Conclusions:
- The developed contactless fingerprinting system offers a viable solution for secure and hygienic biometric authentication.
- This technology can significantly reduce the transmission of contagious infections in various settings.
- The system overcomes limitations of previous contactless methods, offering high accuracy and usability.
