Avaliação da comunicabilidade das configurações de privacidade do Facebook em plataforma Android

Abstract

In the digital, computer-driven world we live in today, with a myriad of new technologies emerging every day, there's an ever increasing number of social networks available. This raises privacy concerns on its members about how their data are being secured, since the purpose of these networks is exposure. One example is the social network Facebook, in which each user has a list of friends and can share pictures, thoughts, videos, location and other information with them so they can like and comment. As a very relevant and big social network, Facebook offers privacy settings for its users to assist them to preserve their information. However, these settings not always can be accessed easily by its members. To detect possible interface disruptions there are methods of HCI (Human-Computer Interaction) that are responsible for analyzing the emission and reception of the message created by the designer of the systems, methods which are based on Semiotics Engineering. The methods that were chosen were the Semiotic Inspection Method (SIM) and the Communicability Evaluation Method (CEM). For the execution of both methods, the same tasks needed to be created and used. These two methods are widely used because their results generally complement each other. The difference is that the SIM was conducted by the evaluator and the CEM was realized with six users. In the results a few communication ruptures were found in the CEM although not seen in the SIM, but in some cases the same breakdowns were found in the results of both methods. It was concluded that Facebook has a concern with the information of its members and offers several privacy setting options. However, in some cases the users are not receiving that message. They simply prefer not to expose their data for fear of the repercussions that this could bring. This further demonstrates that the users understand the risks of the lack of privacy, but do not know how to use Facebook tools to ensure their privacy.
