Biometric Authentication System on Mobile Personal Devices

Abstract—We propose a secure, robust, and low-cost biomet-ric authentication system on the mobile personal device for the personal network. The system consists of the following five key modules: 1) face detection; 2) face registration; 3) illumination normalization; 4) face verification; and 5) information fusion. For the complicated face authentication task on the devices with limited resources, the emphasis is largely on the reliability and applicability of the system. Both theoretical and practical consid-erations are taken. The final system is able to achieve an equal error rate of 2 % under challenging testing protocols. The low hardware and software cost makes the system well adaptable to a large range of security applications.
