Definition of private information for image sharing in social networking services

Abstract

With the increasing use of online image sharing and social networks, such as Facebook or Instagram, people share more and more personal information and privacy issues can arise. Such issues are already occurring and people are becoming aware of it. Helping them managing their privacy and improving privacy awareness has become essential. Recent studies have gathered testimonies of regrets and users’ concerns or created access control systems that help the users to manage their privacy. However, there is no guidelines to define privacy-sensitive information contained in images. In this work, we propose a classification table of private information for images in Social Networking Services as such guidelines in order to improve privacy awareness and prevent future privacy invasion. We then verify it by submitting the table to the users and asking them to rank information according to privacy level. Results reveal that people agree to it and feel the need of such classification table. Finally propose a method that uses these guidelines in order to create settings for access control.
