Physical-layer device identification aims at identifying wireless devices during radio
communication by exploiting unique characteristics of their analog (radio) circuitry. This work …

Information technology can improve the quality, efficiency, and cost of healthcare. In this
survey, we examine the privacy requirements of mobile computing technologies that have …

With the rapid growth of the Internet-of-Things (IoT), concerns about the security of IoT
devices have become prominent. Several vendors are producing IP-connected devices for …

The Internet-of-Things (IoT) has brought in new challenges in device identification--what the
device is, and authentication--is the device the one it claims to be. Traditionally, the …

MAC address randomization is a privacy technique whereby mobile devices rotate through
random hardware addresses in order to prevent observers from singling out their traffic or …

We design, implement, and evaluate a technique to identify the source network interface
card (NIC) of an IEEE 802.11 frame through passive radio-frequency analysis. This …

As mobile begins to overtake the fixed Internet access, ad networks have aggressively
sought methods to track users on their mobile devices. While existing countermeasures and …

Smartphones with Wi-Fi enabled periodically transmit Wi-Fi messages, even when not
associated to a network. In one 12-hour trial on a busy road (average daily traffic count …

We present several novel techniques to track (unassociated) mobile devices by abusing
features of the Wi-Fi standard. This shows that using random MAC addresses, on its own …

The rapid deployment of smartphones as all-purpose mobile computing systems has led to a
wide adoption of wireless communication systems such as Wi-Fi and Bluetooth in mobile …
