Biometrie authentication using hand movement information from wrist-worn PPG sensors

摘要: Recently, wrist-worn smart devices such as smart-watches are becoming popular, and there is a growing need for authentication systems on devices. Many contain photoplethysmographic (PPG) sensor with purpose of measuring the user's heart rate. In this paper, in addition to using PPG measure rate, we use it detect hand movement. our proposed method, not only information movement, but also that stationary state improve robustness authentication. We obtained signals from 15 subjects, whom experiment were asked bend their wrist put back several times, continuously. The results experiments revealed continuous movement three times achieved an equal error rate 11.6 %, nine 8.8 %.
