Active service discovery in WiFi, makes wireless station broadcast their WiFi fingerprint, i.e. the SSIDs of their preferred wireless networks. Our hypothesis is that social links between devices owner can be identified by exploiting the information contain in the fingerprint. More specifically we propose to consider the similarity between fingerprint as a metric, with the underlying idea: similar fingerprint are likely to be linked. We study the performances of several similarity metric on a controlled dataset. Then we apply the the designed classifier to a dataset collected in the wild. Finally we discuss how WiFi fingerprint can reveal informations on the nature of the links between users. This study is based on a dataset collected in Sydney that is composed fingerprints corresponding to more than 30.000 devices.


Wi-Fi, privacy, security
