I Know Who You Will Meet This Evening! Linking Wireless Devices Using Wi-Fi Probe Requests
Active service discovery in Wi-Fi involves wireless stations broadcasting their Wi-Fi fingerprint, i.e., the SSIDs of their preferred wireless networks. The content of those Wi-Fi fingerprints can reveal different types of information about the owner. The authors focus on the relation between the fingerprints and the links between the owners. Their hypothesis is that social links between devices owners can be identified by exploiting the information contained in the fingerprint. More specifically they propose to consider the similarity between fingerprints as a metric, with the underlying idea: similar fingerprints are likely to be linked.
