Anti-spoofing device for biometric fingerprint scanners

Biometrics is a promising technology for safeguarding the personal identity and digital information of every individual. This paper describes an easy-to-integrate and inexpensive method to improve the security of fingerprint scanners. An added layer of protection is proposed by integrating an anti-spoofing device that can be integrated to any commercial fingerprint scanners to enhance their security and prevent spoofing from prosthetic or dismembered fingers. The proposed device senses the capacitance and pulses from human fingers. We conducted over 300 tests on human and fake fingers. Our experimental results demonstrate that this novel device can identify the fake fingers with 100% accuracy. The device has a potential for being a cost-efficient and robust solution against spoofing.
