A hybrid biometric system using touch-panel-based finger-vein identification and deformable-registration-based face identification

A hybrid biometric system, which is combined with a touch-panel-based finger-vein-identification device and a deformable-registration-based face-identification module, is proposed. For this system, the touch-panel-based device is developed for access control at a facility. For finger-vein identification, a user only needs to touch the device screen. At the same time, face images of the user are acquired and enrolled in the face-identification module. Access control and surveillance inside the facility are performed by the face-identification module. The touch-panel-based device can not only provide high-accuracy authentication but also greatly reduce the user's burden during finger-vein-pattern acquisition. Furthermore, a face-alignment and identification algorithm based on deformable registration is proposed. A performance evaluation of the proposed hybrid biometric system demonstrated that the system can provide biometric authentication with both high reliability and user convenience.
