Our paper „The Measurable Environment as Nonintrusive Authentication Factor on the Example of WiFi Beacon Frames” got accepted at ETAA 2022! In the paper, we describe a novel location-based authentication mechanism that uses the Wi-Fi signals that surround us at a specific location in order to recognize that location. The approach only relies on the capability features in Wi-Fi beacon frames, which can solely be used for the recognition, but not the localization of a specific place; this makes the approach privacy aware.
