More and more frequently, users are called to make decisions concerning the disclosure of their personal information. In this study, we investigate the factors affecting users’ choices toward the disclosure of their personal data, including not only their demographic and self-reported individual characteristics, but also their social interactions and their mobility patterns inferred from months of mobile phone data activity. We report the findings of a field study conducted with a community of 63 subjects provided with (i) a smart-phone and (ii) a Personal Data Store (PDS) enabling them to control the disclosure of their data. We monitor the sharing behavior of our participants through the PDS and evaluate the contribution of different factors affecting their disclosing choices of location and social interaction data. Our analysis shows that social interaction inferred by mobile phones is an important factor revealing willingness to share, regardless of the data type. In addition, we provide further insights on the individual traits relevant to the prediction of sharing behavior. date: 2017-05 publisher: ASSOC COMPUTING MACHINERY official_url: http://dx.doi.org/10.1145/3017431 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1206626 doi: 10.1145/3017431 lyricists_name: Musolesi, Mirco lyricists_id: MMUSO05 actors_name: Musolesi, Mirco actors_id: MMUSO05 actors_role: owner full_text_status: public publication: ACM Transactions on Internet Technology volume: 17 number: 2 article_number: 13 pages: 19 issn: 1557-6051 citation: Perentis, C; Vescovi, M; Leonardi, C; Moiso, C; Musolesi, M; Pianesi, F; Lepri, B; (2017) Anonymous or Not?
