Survey: Evaluation Study of Privacy Conflicts in OSNs

Abstract — In the age of the Internet, privacy is a luxury and you have to constantly be on your heels to maintain it. OSN makes it particularly hard for users to guard their personal data. Besides many changes, Facebook privacy settings remain complicated. Even, past updates have unexpectedly made previously private information available to the public. It is difficult to balance the right of privacy and control of personal information when individuals voluntarily place personal information on their profile. Once information is placed on public domains users can easily lose control over who sees it and that may use it. While privacy settings are there to protect users, in practice this is not always the case, whether it is because of slack web design or through lack of knowledge or care by the user. Your data is shared more widely. Even if you have restricted your information to be seen by friends only, friends who are using a Facebook app could allow your data to be transferred to a third party without your permission. Remember: Sharing info with “friends of friends ” could expose it to tens of thousands. A new approach is proposed to enable the protection of shared data in OSNs. A different Access control model is formulated to capture the essence of multiple authorizations, along with an access policy specification scheme and a policy mechanism. Along with, logical representation of access control model which allows us to leverage the features of existing logic solvers to perform various analysis tasks on our model. Here also discuss a proof-of-concept prototype as part of an application in Facebook and provide usability study and system evaluation of our method. Keywords—privacy conflicts, online networks, security, protection, data sharing. I
