Invisible Cloak Fails: CSI-based Passive Human Detection

Published: 01 November 2015 Publication History

Abstract

WiFi signals have attracted extensive attention for context-aware due to its ubiquity. Traditional WiFi sensing methods mainly adopt Received Signal Strength Indication (RSSI), however the coarse features hamper its expansion. To achieve more finger-grained information, Channel State Information (CSI) is introduced for sensing, based on which, we design a directional human detection scheme via data prediction, which aims to visualize the variations of CSI when human appears. However, this scheme suffers from the limitations caused by the link-centric architecture of WiFi. Considering the demands for omni-directional coverage of some scenarios (e.g. museum exhibition), we propose a omni-directional detection scheme based on fingerprinting utilizing the relationship between the CSI signal features and locations. Experiments are processed in actual scenarios and experimental results verify the feasibility of our two schemes.
