Over the past few decades, hand-based multimodal biometrics systems have achieved significant attention because of their high security, accuracy, and anti-counterfeiting. Various hand physiological biometric modalities have been explored for identity authentication, i.e., fingerprint, finger knuckle...

Biometric recognition systems based on ultrasonic images have several advantages over other technologies, including the capability of capturing 3D images and detecting liveness. In this work, a recognition system based on hand geometry achieved through ultrasound images is proposed and experiment...

In this work, an improved ultrasound technique for biometric recognition is proposed. It allows to acquire simultaneously two biometric characteristics: 3D Hand Geometry and 3D Palmprint. An open research platform is employed as ultrasound imaging system. A commercial high frequency probe is move...

Hand geometry has been a widely used biometric authentication because it is generally believed that the human hand has sufficient anatomical features which could be used for personal identification. Many hand geometry systems use pegs, which guide hand placement on the scanner. The system prompts th...

The raging COVID-19 pandemic accentuates the urgent and compelling need for non-contact fingerprinting biometric authentication devices to mitigate the transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and other contagious infections. Current approaches to contactless ...
