dc.description.abstractThe Internet of Things (IoT) is growing rapidly thanks to the convenience it provides to users, as sensors collect, communicate, and collaborate with each other to provide better services. Wi-Fi cameras from a variety of manufacturers have been widely adopted to provide inexpensive monitoring services to general consumers. Although Wi-Fi cameras provide real-time monitoring, these devices often come with weak security mechanisms. This allows adversaries to exploit those IoT devices and have total control over with admin privileges. Moreover, those Wi-Fi cameras can be installed with bad intentions. Several incidents have been reported, where hidden Wi-Fi cameras are found in rental services such as Airbnb. To counter Wi-Fi camera spying and monitoring, we proposed a novel method to detect hidden Wi-Fi cameras, using timing analysis and a mobile phone as a detector. In order to provide constant and faster communication, IoT devices often required low-latency networks. Accordingly, the proposed methodology performs statistical analysis (Correlation Coefficient, Dynamic Time Warping, Kullback-Leibler divergence, and Jensen-Shannon divergence) to measure the similarity scores of network traffic streams and the recorded video from the mobile phone. Further, the similarity score is then used to identify hidden Wi-Fi cameras in the environment. The results of our experiments show that the proposed detection methodology can successfully discover hidden Wi-Fi cameras with an accuracy rate of 97.436%.
