… WiKey consists of two Commercial Off-The-Shelf (COTS) WiFi devices, a sender (such as a …

… To the best of our knowledge, LiKey is the first location -independent keystroke recognition
system on numeric keypads using WiFi. It generalizes well to different keystroke regions, and …

… We propose a novel keystroke recognition system called WiKey. When the user enters the …
of different keystrokes will introduce a unique interference to the multi-path signals, which can …

… We cancel the signals received on multiple antennas. The key insight to realizing a fine-…

… human subtle motions, such as keystrokes. Therefore, we build a signal enhancement model
using Ricean distribution to amplify user keystroke dynamics and a hybrid learning model …

… First, we demonstrate the feasibility of using WiFi signals from COTS devices for gait
recognition. Second, we propose signal processing techniques to convert raw noisy WiFi signals to …

… for keystroke inference. In this paper, we propose Wi-Crack, a keystroke recognition system
… Two computers equipped with commercial off-the-shelf WiFi NIC comprise the system, with …
