Palmprint Verification System with Dual-Line-Single-Point Assistance on Android Mobile Devices

Palmprint has several advantages in authentication on mobile devices; however, some serious challenges severely restrict the development of palmprint verification in mobile environments, such as various locations and gestures of hand, complex backgrounds, diverse illuminations, limited hardware resources. In order to overcome the aforementioned problems, we designed and implemented a novel palmprint verification system with an assistance technique, namely dual-line-single-point (DLSP), on Android mobile devices. The environment setup and variable configuration on Android operating system were carried out according to the demand analysis. In software subsystem, the main interface and image capture interface were designed to meet the system requirements. All kinds of classes and threads were programmed in Java language. Finally the software and hardware were jointly debugged. The sufficient test results confirm the effectiveness and practicability of the developed palmprint verification system.
