A Systematic Mapping about User Sensitive Information on Social Networks

Social networks are used by millions of users every day and become part of our lives. However, privacy and security issues have been raised since user´s sensitive information are exposed by several manners. User´s sensitive information disclosure is not solved yet by current social networks. Thus several researches have been done in order to understand implications and users awareness. Different approaches and techniques are applied on every study resulting a heterogeneous set of information. In order to better understand the current state of the literature about user´s privacy disclosure and security we conducted a review of published papers on IEEE, ACM and Science Direct using a systematic mapping. We evaluated 143 papers and classified 35 under our defined criteria to consider only studies with experiment on user privacy and security disclosure. Results indicate an academic preference to conduct questionnaire approaches aiming to explore user´s awareness. We also notice that most of studies are limited to small groups and that research community is basically restricted to USA, Europe and Asia.
