Personalized breath based biometric authentication with wearable multimodality
Manh-Ha Bui, Viet-Anh Tran, Cuong Pham
Breath with nose sound features has been shown as a potential biometric in personal identification and verification. In this paper, we show that information that comes from other modalities captured by motion sensors on the chest in addition to audio features could further improve the performance. Our work is composed of three main contributions: hardware creation, dataset publication, and proposed multimodal models. To be more specific, we design new hardware which consists of an acoustic sensor to collect audio features from the nose, as well as an accelerometer and gyroscope to collect movement on the chest as a result of an individual's breathing. Using this hardware, we publish a collected dataset from a number of sessions from different volunteers, each session includes three common gestures: normal, deep, and strong breathing. Finally, we experiment with two multimodal models based on Convolutional Long Short Term Memory (CNN-LSTM) and Temporal Convolutional Networks (TCN) architectures. The results demonstrate the suitability of our new hardware for both verification and identification tasks.
