802.11 Mac

We present two novel noncooperative MAC layer fingerprinting and tracking techniques for Wi-Fi (802.11) enabled mobile devices. Our first technique demonstrates how a per-bit entropy analysis of a single captured frame allows an adversary to construct a fingerprint of the transmitter that is 80.0 to 67.6 percent unique for 50 to 100 observed devices and 33.0 to 15.1 percent unique for 1,000 to 10,000 observed devices. We show how existing mitigation strategies such as MAC address randomization can be circumvented using only this fingerprint and temporal information. Our second technique leverages peer-to-peer 802.11u Generic Advertisement Service (GAS) requests and 802.11e Block Acknowledgement (BA) requests to instigate transmissions on demand from devices that support these protocols. We validate these techniques using two datasets, one of which was recorded at a music festival containing 28,048 unique devices and the other at our research lab containing 138 unique devices. Finally, we discuss a number of countermeasures that can be put in place by mobile device vendors in order to prevent noncooperative tracking through the discussed techniques.

In this paper we present the ESPIM system, a set of tools that enables the authoring of intervention programs with focus on health and education. Created programs are played in a mobile app that generates screens on demand, according to their definition provided by JSON fi les. Using state-of-art technology we aim to provide a platform that can be used by professionals of health and education with no programming skills. To achieve that the system presents an intuitive authoring interface, built with requirements obtained with experts in diff erent areas and with continuous feedback from evaluations, and a friendly mobile app, which presents elementsthat users are familiar and a good aesthetic design to motivate them. The system is being successfully used by professionals in health-related areas and shows many advantages in comparison tosimilar platforms.
