Research on High-Speed Face Authentication Algorithm for IoT Devices

Face authentication is considered as the most convenient approach of biometric authentication techniques and has been put into practical use in various situations. But face has a significant feature that other biometrics do not have is it keeps changing lifelong. Even in the morning or at night, with the body conditions good or bad, face shows different appearance. Furthermore, the accuracy of face authentication is also affected by changes in facial expressions and face orientation. There are also many technical difficulties because the face authentication requires both compatibility of accuracy and speed, but it is difficult to implement complicated calculations into an impotent devices. This study proposes a simple face authentication algorithm for IoT devices. Proposed method obtains a certain level of face authentication accuracy and high speed operation can be achieved at the same time.
