Recognition of human activities and gestures using preexisting WiFi signals has been
shown to be feasible in recent studies. Given the pervasiveness of WiFi signals, this …

Researchers have demonstrated the feasibility of detecting human motion behind the wall
with radio frequency (RF) sensing techniques. With these techniques, an eavesdropper can …

Abstract Channel State Information (CSI)-based localization with 802.11 has been proven
feasible in multiple scenarios and is becoming a serious threat to people's privacy in …

The intrinsic hardware imperfection of WiFi chipsets manifests itself in the transmitted signal,
leading to a unique radiometric fingerprint. This fingerprint can be used as an additional …

Wi-Fi sensing technology plays an important role in numerous IoT applications such as
virtual reality, smart homes and elder healthcare. The basic principle is to extract physical …

CSI (Channel State Information) of WiFi systems contains the environment channel
response between the transmitter and the receiver, so the people/objects and their …

In this paper, we first present a new privacy leak in residential wireless ubiquitous computing
systems, and then we propose guidelines for designing future systems to prevent this …

Wi-Fi signals may help realize low-cost and non-invasive human sensing, yet it can also be
exploited by eavesdroppers to capture private information. Very few studies rise to handle …

A myriad of IoT devices such as bulbs, switches, speakers in a smart home environment
allow users to easily control the physical world around them and facilitate their living styles …

The increasing ubiquity of low-cost wireless sensors has enabled users to easily deploy
systems to remotely monitor and control their environments. However, this raises privacy …
