Summary
This study introduces a novel anti-spoofing method for fingerprint sensors using pulse oximetry. The technique reliably detects fake fingerprints, enhancing biometric security against sophisticated attacks.
Area of Science:
- Biometrics
- Sensor Technology
- Physiological Computing
Background:
- Fingerprint sensors are widely used but vulnerable to spoofing attacks.
- Artificial or dismembered fingerprints can deceive current commercial systems.
- Liveness detection is crucial for robust biometric security.
Purpose of the Study:
- To develop a reliable anti-spoofing method for fingerprint sensors.
- To enhance biometric security by detecting the liveness of a fingerprint.
- To overcome the limitations of existing commercial fingerprint systems against fake inputs.
Main Methods:
- Proposed a liveness detection method based on pulse oximetry principles.
- Utilized a light probe emitting two wavelengths to measure hemoglobin oxygen absorption.
- Calculated oxygen saturation and heart pulse rate to determine biometric liveness.
Main Results:
- The developed prototype successfully identified and thwarted spoof attacks.
- Effectively distinguished between real and fake fingerprints, including those from dismembered fingers.
- Demonstrated the efficacy of pulse oximetry-based liveness detection.
Conclusions:
- The proposed pulse oximetry-based liveness detection offers a reliable solution against fingerprint spoofing.
- This method significantly enhances the security of biometric systems.
- The technology shows promise in preventing sophisticated spoofing attempts.
