The paper “How People Care about Their Personal Data Released on Social Media“ authored by Kellyton Dos Santos Brito, Frederico Araujo Durão Vinicius Cardoso Garcia and Silvio Romero de Lemos Meira has been accepted for publication at 11th International Conference on Privacy, Security and Trust. The conference is being held in Tarragona, Catalonia, July 10-12, 2013.

A brief overview of the paper is given next.

Content sharing services become immensely popular on the Web. More than 1 billion people use this kind of services to communicate with friends and exchange all sorts of information. In this new context, privacy guarantees are essential: guarantees about the potential release of data to unintended recipients and the use of user data by the service provider. Although the general public is concerned about privacy questions related to unintended audiences, data usage by service providers is still misunderstood. In order to further explore this level of misunderstanding, this work presents the results of a survey conducted among 900 people with the aim of discovering how people care about the use of their personal data by service providers in terms of social media. From the results, we found that: (i) in general people do not read license terms and do not know very much about service policies, and when presented with these policies people do not agree with them; (ii) a good number of people would support alternative models such as paying for privacy or selling their personal data; and (iii) there are some differences between generations in relation to how they care about their data.
