Abstract

In recent years, Internet-of-Thing (IoT) has experienced explosive growth and 
rapidly penetrated into our daily life. Sensing is one of its core function to 
bridge digital space and physical world. However, the market of IoT sensing 
applications is still in its infancy and far from maturity. In this thesis, we 
design and build practical systems to explore the potentials of IoT sensing. We 
first focus on the device-device interaction. Specifically, we design a 
lightweight scheme to extract physical-layer signatures of surrounding 
environment to secure wireless interaction between IoT devices. Second, we 
focus on the human-device interaction. Specifically, we exploit the sensing 
capability of IoTs to design two liveness detection systems for heart-sound and 
face authentication respectively to avoid unauthorized access. In addition, we 
propose a driver hand position monitoring system to help improve the driving 
safety. Third, we study the spoofing issue in IoT sensing. We demonstrate 
attack schemes to generate adversarial ECG examples to misguide arrhythmia 
classification systems and adversarial wireless signals to mislead WiFi-based 
gesture recognition systems, which calls attention to adequate countermeasures.
