Attributed to the DNN that identifies physical tampering events due to the multi?subcarrier characteristics in CSI, our methodology takes effect using only one COTS Wi?Fi endpoint with a single embedded antenna to detect changes in the rel-ative orientation between the Wi?Fi infrastructure and the endpoint, in contrast to previous sophis-ticated, proprietary approaches. Preliminary results show that our detectors manage to achieve a 95.89% true positive rate (TPR) with no worse than a 4.12% false positive rate (FPR) in detecting physical tampering events. ? 2021 by the authors.
