Yet their ability to continuously monitor and identify individuals also raises significant privacy concerns. In this work, we propose a method for systematically evaluating the privacy risks of video analytics using real world IoT surveillance video. Our method takes into account policy, edge computation, and camera placement constraints to explore possible configurations and risks. Our evaluation shows that gait recognition is a significant privacy threat that should be considered alongside facial recognition and accounted for in modern privacy policies. Furthermore, we find edge-based verification methods still perform significantly worse than those methods requiring cloud computing. Lastly, we find evidence that color recognition, which we use to identify individuals' shirt colors, can be a helpful modality for increasing identification confidence and efficiency. We believe that the approach we present provides a starting point for reasoning about privacy risks of IoT video analytics under various policy and computation constraints, in both the present and future.</div><div class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"><br class=""></div><div class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">—————————————————————————————————————————————</div><div class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"><br class=""></div></div><br class=""><div class="">
