Radio-Frequency (RF) Imaging Sensor for Advanced Security Fingerprint Biometrics and Mobile Health Monitoring
Current portable and wearable devices use fingerprint analysis for secure authentication. The fingerprint pattern systems analyze only the surface morphology of the fingerprint, making it easy for hackers to spoof and bypass authentication. RF signals can collect tissue information beyond the surface of the finger and can provide increased security...
