Communicability Evaluation of Privacy Settings on Facebook for Android

With the widespread popularization of Facebook, which is considered the most used social network nowadays, a concern has become constant among its users: How is users' data privacy being assured, since one of the purposes of Facebook is actually the exposure of user data? Facebook provides privacy settings that help its users to preserve their information. However, users are not always able to access these settings easily. In order to analyze this question, two methods of evaluation were used: Semiotic Inspection Method (SIM) and Communicability Evaluation Method (CEM). The evaluation was carried out considering a very particular profile: users located in Quixada, a small city of Ceara contryside, a state located in the northeast of Brazil who access Facebook exclusively by mobile phone. We concluded that Facebook has a real concern with its users' information, however, in some cases, they are not receiving this message accordingly. As result, although users understand the risks of lack of privacy, they generally did not know how to use Facebook's tools to ensure their privacy.
