Multifeature Palmprint Authentication

Abstract

A 2D-based palmprint authentication system is easily fooled by spoof attacks, such as a fake palmprint. To solve that problem, we present a multifeature palmprint authentication system using both 2D and 3D palmprint features in this chapter. This chapter is organized as follows: Sect. 6.1 briefly introduces the background of 2D- and 3D-based palmprint authentication systems. Section 6.2 presents a multifeature palmprint authentication system and the 2D and 3D palmprint image acquisition device. In Sect. 6.3, 2D and 3D feature extraction algorithms are presented. In Sect. 6.4, we present a 2D features matching algorithm for 2D palmprint verification, and then present a 3D features matching algorithm for 3D palmprint authentication. Some experiments are reported to illustrate the robustness of the presented algorithm in Sect. 6.5. The chapter is concluded in Sect. 6.6.
