Original Abstract

The focus on privacy related measures regarding wireless networks grew in last couple of years. This is especially important with technologies like Wi-Fi or Bluetooth, which are all around us and our smartphones use them not just for connection to the internet or other devices, but for localization purposes as well. In this paper we analyse and evaluate probe request frames of 802.11 wireless protocol captured during the 11th international conference on Indoor Positioning and Indoor Navigation (IPIN) 2021. We explore the temporal occupancy of the conference space during four days of the conference as well as non-cooperatively track the presence of devices in the proximity of the session rooms using 802.11 management frames, with and without using MAC address randomization. We carried out this analysis without trying to identify/reveal the users identity or in any way reverse the MAC address randomization. As results of the analysis, we detected that there are still many devices not adopting MAC randomization, because either it is not implemented or users disabled it. In addition, many devices can be easily tracked despite employing MAC randomization.
