An improved ultrasound system for biometric recognition based on hand geometry and palmprint

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 moved in the elevation direction over the region of interest by an automated scanning system based on numeric controlled pantograph. Experimental results are presented and the advantages of the proposed technique are highlighted and discussed.
